This evening, someone pointed out Congressional testimony I gave over 6 years ago. This referenced similar testimony I gave in 2001, and I prepared it using notes from lectures I gave in the early-to-mid 1990s.
What is discouraging is that if I were asked to provide testimony next week, I would only need to change a few numbers in this document and it could be used exactly as is. The problems have not changed, the solutions have not been attempted, and if anything, the lack of leadership in government is worse.
Some of us have been saying the same things for decades. I’m approaching my 3rd decade of this, and I’m a young’un in this space.
If you are interested, read the testimony from 2009 and see what you think.
On September 24 and 25 of this year, Purdue University hosted the second Dawn or Doom symposium. The event — a follow-up to the similarly-named event held last year — was focused on talks, movie, presentations, and more related to advanced technology. In particular, the focus has been on technology that poses great potential to advance society, but also potential for misuse or accident that could cause great devastation.
I was asked to speak this year on the implications of surveillance capabilities. These have the promise of improving use of resources, better marketing, improved health care, and reducing crime. However, those same capabilities also threaten our privacy, decrease some potential for freedom of political action, and create an enduring record of our activities that may be misused.
My talk was videotaped and is now available for viewing. The videographers did not capture my introduction and the first few seconds of my remarks.The remaining 40 or so minutes of me talking about surveillance, privacy, and tradeoffs are there, along with a few audience questions and my answers.
If you are interested, feel free to check it out. Comments welcome, especially if I got something incorrect — I was doing this from memory, and as I get older I find my memory not not be quite as trustworthy as it used to be.
You can find video of most of the other Dawn or Doom 2 events online here. The videos of last year's Dawn or Doom event are also online. I spoke last year about some of the risks of embedding computers everywhere, and giving those systems control over safety-critical decisions without adequate safeguards. That talk, Faster Than Our Understanding , includes some of the same privacy themes as the most recent talk, along with discussion of security and safety issues.
Yes, if you saw the news reports, the Dawn or Doom 2 event is also where this incident involving Barton Gellman occurred. Please note that other than some communication with Mr. Gellman, I played absolutely no role in the taping or erasure of his talk. Those issues are outside my scope of authority and responsibility at the university, and based on past experience, almost no one here listens to my advice even if they solicit it. I had no involvement in any of this, other than as a bystander.
Purdue University issued a formal statement on this incident. Related to that statement, for the record, I don’t view Mr. Gellman’s reporting as “an act of civil disobedience.” I do not believe that activities of the media, as protected by the First Amendment of the US Constitution and by legal precedent, can be viewed as “civil disobedience” any more than can be voting, invoking the right to a jury trial, or treating people equally under the law no matter their genders or skin colors. I also share some of Mr. Gellman’s concerns about the introduction of national security restrictions into the entire academic environment, although I also support the need to keep some sensitive government information out of the public view.
That may provide the topic for my talk next year, if I am invited to speak again.
I recently had a couple of students (and former students, and colleagues) ask me if I was attending any of a set of upcoming cons (non-academic/organizational conferences) in the general area of cyber security. That includes everything from the more highly polished Black Hat and DefCon events, to Bsides events, DerbyCon, Circle City Con, et al. (I don’t include the annual RSA Conference in that list, however.)
25 years ago there were some as the field was starting up that I attended. One could argue that some of the early RAID and SANS conferences fit this category, as did some of the National Computer Security Conferences. I even helped organize some of those events, including the 2nd RAID workshop! But that was a long time ago. I don’t attend cons now, and haven’t for decades. There are two main reasons for that.
First, is finances. Some of the events are quite expensive to attend — travel, housing, and registration all cost money. As an academic faculty member, and especially as one at a state university, I don’t have a business account covering things like these as an expense item. Basically, I would have to pay everything out of pocket, and that isn’t something I can afford to do on a regular (or even sporadic) basis. I manage to scrape up enough to attend the main RSA conference each year, but that is it.
Yes, faculty do sometimes have some funds for conferences. When we have grants from agencies such as NSF or DARPA, they often include travel funds, but usually we target those for places where the publication of our research (and that of our students) gives the most academic credit — IEEE & ACM events, for instance. Sometimes donors will provide some gifts to the university for us to use on things not covered by grants, including travel. And some faculty have made money by spinning off companies and patenting their inventions, so they can use that.
None of that describes my situation. Over the last 20 years I have devoted most of my efforts at raising (and spending) funds towards the COAST lab and then CERIAS. When I have had funding for conferences, I have usually spent it on my students, first, to allow them to get the professional exposure. There is seldom money left over for me to attend anything. I show up at a few events because I’m invited to speak and the hosts cover the expenses. The few things I’ve invented I’ve mostly put out in the public domain. I suppose it would be great if some donor provided a pot of money to the university for me to use, but I’ve gotten in the habit of spending what I have on junior colleagues and students so I’m not sure what I’d do with it!
There is also the issue of time. I have finite time (and it seems more compressed as I get older) and there are only so many trips I have time (and energy) to make, even if I could afford more. Several times over the last few years I’ve hit that limit, as I’ve traveled for CERIAS, for ACM, and for some form of advising, back to back to back.
Second, I’m not sure I’d learn much useful at most cons. I’ve been working (research, teaching, advising) in security and privacy for 30 years. I think I have a pretty good handle on the fundamentals, and many of the nuances. Most cons present either introductions for newbies, or demonstrations of hacks into existing systems. I don’t need the intros, and the hacks are not at all surprising. There is some great applications engineering work being done by the people involved, but unlike some people, I don’t need to see an explicit demonstration to understand the weaknesses in supply chains, poor authentication, lack of separation, no root of trust, and all the other problems that underlie those hacks. I eventually hear about the presentations after the fact when they get into the news; I can’t recall hearing about any that really surprised me for quite some time now.
I wish leaders in government and business didn’t need to be continually bashed with demonstrations to begin to get the same points about good security, but I’ve been trying to explain these issues for nearly my whole career, and they simply don’t seem to listen after “This will cost more than you are currently spending.” If anything, attending con events simply points out that the message I’ve been trying to convey for so long has not been heard; rather than instructive, cons might well be rather depressing for me.
There’s obviously also a social element to these events — including the more academic and professional conferences — that I am clearly missing out on. I do have a little regret over that. I don’t get to meet some of the young up-and-coming people in the field, on either the research or applied ends of things. I also don’t get to see some of people I already know as often as I wish I did. However, that gets back to cost and time. And I don’t think too many people have noticed the difference or bemoaned a loss because I wasn’t there, especially as I have gotten older. The current crop of practitioners are all excited by learning the most recent variation on a theme — someone who points out that it is all material we could have predicted (and prevented) isn’t going to fit in. Frankly, I was surprised to hear there was any interest in Jack Daniel’s “Shoulders of Infosec” project by some of the con crowd!
So, do I hate cons? No, not at all! If colleagues or students find them of value and they have the time and resources to attend, then they should go…but they aren’t likely to see me attending.
The U.S. limits the export of certain high-tech items that might be used inappropriately (from the government’s point of view). This is intended to prevent (or slow) the spread of technologies that could be used in weapons, used in hostile intelligence operations, or used against a population in violation of their rights. Some are obvious, such as nuclear weapons technology and armor piercing shells. Others are clear after some thought, such as missile guidance software and hardware, and stealth coatings. Some are not immediately clear at all, and may have some benign civilian uses too, such as supercomputers, some lasers, and certain kinds of metal alloys.
Recently, there have been some proposed changes to the export regulations for some computing-related items. In what follows, I will provide my best understanding of both the regulations and the proposed changes. This was produced with the help of one of the professional staff at Purdue who works in this area, and also a few people in USACM who provided comments (I haven’t gotten permission to use their names, so they’re anonymous for now). I am not an expert in this area so please do not use this to make important decisions about what is covered or what you can send outside the country! If you see something in what follows that is in error, please let me know so I can correct it. If you think you might have an export issue under this, consult with an appropriate subject matter expert.
Some export restrictions are determined, in a general way, as part of treaties (e.g., nuclear non-proliferation). A large number are as part of the Wassenaar Arrangement — a multinational effort by 41 countries generally considered to be allies of the US, including most of NATO; a few major countries such as China are not, nor are nominal allies such as Pakistan and Saudi Arabia (to name a few). The Wassenaar group meets regularly to review technology and determine restrictions, and it is up to the member states to pass rules or legislation for themselves. The intent is to help promote international stability and safety, although countries not within Wassenaar might not view it that way.
In the U.S., there are two primary regulatory regimes for exports: ITAR and EAR. ITAR is the International Traffic in Arms Regulations in the Directorate of Defense Trade Controls at the Department of State. ITAR provides restrictions on sale and export of items of primary (or sole) use in military and intelligence operations. The EAR is the Export Administration Regulations in the Bureau of Industry and Security at the Department of Commerce. EAR rules generally cover items that have “dual use” — both military and civilian uses.
These are extremely large, dense, and difficult to understand sets of rules. I had one friend label these as “clear as mud.” After going through them for many hours, I am convinced that mud is clearer!
Items designed explicitly for civilian applications without consideration to military use, or with known dual-use characteristics, are not subject to the ITAR because dual-use and commodity items are explicitly exempted from ITAR rules (see sections 121.1(d) and 120.41(b) of the ITAR). However, being exempt from ITAR does not make an item exempt from the EAR!
If any entity in the US — company, university, or individual — wishes to export an item that is covered under one of these two regimes, that entity must obtain an export license from the appropriate office. The license will specify what can be exported, to what countries, and when. Any export of a controlled item without a license is a violation of Federal law, with potentially severe consequences. What constitutes an export is broader than some people may realize, including:
Those last two items are what as known as a deemed export because the item didn’t leave the U.S., but information about it is given to a non-US person. There are many other special cases of export, and nuances (giving control of a spacecraft to a foreign national is prohibited, for example, as are certain forms of reexport). This is all separate from disclosure of classified materials, although if you really want trouble, you can do both at the same time!
This whole export thing may seem a bit extreme or silly, especially when you look at the items involved, but it isn’t — economic and military espionage to get this kind of material and information is a big problem, even at research labs and universities. Countries that don’t have the latest and greatest factories, labs, and know-how are at a disadvantage both militarily and economically. For instance, a country (.e.g, Iran) that doesn’t have advanced metallurgy and machining may not be able to make specialized items (e.g., the centrifuges to separate fissionable uranium), so they will attempt to steal or smuggle the technology they need. The next best approach is to get whatever knowledge is needed to recreate the expertise locally. You only need to look at the news over a period of a few months to see many stories of economic theft and espionage, as well as state-sponsored incidents.
This brings us to the computing side of things. High speed computers, advanced software packages, cryptography, and other items all have benign commercial uses. However, they all also have military and intelligence uses. High speed computers can be used in weapons guidance and design systems, advanced software packages can be used to model and refine nuclear weapons and stealth vehicles, and cryptography can be used to hide communications and data. As such, there are EAR restriction on many of these items. However, because the technology is so ubiquitous and the economic benefit to the U.S. is so significant, the restrictions have been fairly reasonable to date for most items.
Software is a particularly unusual item to regulate. The norm in the community (for much of the world) is to share algorithms and software. By its nature, huge amounts of software can be copied onto small artifacts and taken across the border, or published on an Internet archive. In universities we regularly give students from around the world access to advanced software, and we teach software engineering and cryptography in our classes. Restriction on these kinds of items would be difficult to enforce, and in some cases, simply silly to restrict.
Thus, the BIS export rules contain a number of exemptions that remove some items from control entirely. (In the following, designations such as 5D002 refer to classes of items as specified in the EAR, and 734.8 refers to section 734 paragraph 8.)
The exemption for publication is interesting. Anyone doing research on controlled items appears to have an exemption under EAR 740.13(e) where they can publish (including posting on the Internet) the source code from research that falls under ECCN 5D002 (typically, cryptography) without restriction, but must notify BIS and NSA of digital publication (email is fine, see 740.13(e.3)); there is no restriction or notification requirement for non-digital print. What is not included is any publication or export (including deemed export) of cryptographic devices or object code not otherwise exempt (object code whose corresponding source code is exempt is itself exempt), or for knowing export to one of the prohibited countries (E:1 from supplement 1 of section 740 — Cuba, Iran, DPRK, Sudan and Syria, although Cuba may have just been removed.)
As part of an effort to harmonize the EAR and ITAR, a proposed revision to both has been published on June 3 (80 FR 31505) that has a nice side-by-side chart of some of these exemptions, along with some small suggested changes.
The Wassenaar group agreed to some changes in December 2013 to include intrusion software and network monitoring items of certain kinds on their export control lists. The E.U. adopted new rules in support of this in October of 2014. On May 20, 2015, the Department of Commerce published — in the Federal Register (80 FR 28853) — a request for comments on its proposed rule to amend the EAR. Specifically, the notice stated:
The Bureau of Industry and Security (BIS) proposes to implement the agreements by the Wassenaar Arrangement (WA) at the Plenary meeting in December 2013 with regard to systems, equipment or components specially designed for the generation, operation or delivery of, or communication with, intrusion software; software specially designed or modified for the development or production of such systems, equipment or components; software specially designed for the generation, operation or delivery of, or communication with, intrusion software; technology required for the development of intrusion software; Internet Protocol (IP) network communications surveillance systems or equipment and test, inspection, production equipment, specially designed components therefor, and development and production software and technology therefor. BIS proposes a license requirement for the export, reexport, or transfer (in-country) of these cybersecurity items to all destinations, except Canada. Although these cybersecurity capabilities were not previously designated for export control, many of these items have been controlled for their "information security" functionality, including encryption and cryptanalysis. This rule thus continues applicable Encryption Items (EI) registration and review requirements, while setting forth proposed license review policies and special submission requirements to address the new cybersecurity controls, including submission of a letter of explanation with regard to the technical capabilities of the cybersecurity items. BIS also proposes to add the definition of "intrusion software" to the definition section of the EAR pursuant to the WA 2013 agreements. The comments are due Monday, July 20, 2015.
The actual modifications are considerably more involved than the above paragraph, and you should read the Federal Register notice to see the details.
This proposed change has caused some concern in the computing community, perhaps because the EAR and ITAR are so difficult to understand, and because of the recent pronouncements by the FBI seeking to mandate “back doors” into communications and computing.
The genesis of the proposed changes is stated to match the Wassenaar additions of (basically) methods of building, controlling, and inserting intrusion software; technologies related to the production of intrusion software; technology for IP network analysis and surveillance, or for the development and testing of same. These are changes to support national security, regional stability, and counter terrorism.
According to the notice, intrusion software includes items that are intended to avoid detection or defeat countermeasures such as address randomization and sandboxing, and exfiltrate data or change execution paths to provide for execution of externally provided instructions. Debuggers, hypervisors, reverse engineering, and other software tools are exempted. Software and technology designed or specially modified for the development, generation, operation, delivery, or communication with intrusion software is controlled — not the intrusion software itself. It is explicitly stated that rootkits and zero-day exploits will presumptively be denied licenses for export.
The proposed changes for networking equipment/systems would require that it have all 5 of the following characteristics to become a controlled item:
Equipment specially designed for QoS, QoE, or marketing is exempt from this classification.
Two other proposed changes would remove the 740.13(d) exemption for mass-market products, and would make software controlled by one of these new sections and containing encryption would now be dual-listed in two categories. There are other changes for wording, cleaning up typos, and so on.
I don’t believe there are corresponding changes to ITAR because these all naturally fall under the EAR.
Although social media has had a number of people posting vitriol and warnings of the impending Apocalypse, I can’t see it in this change. If anything, this could be a good thing — people who are distributing tools to build viruses, botnets, rootkits and the like may now be prosecuted. The firms selling network monitoring equipment that is being used to oppress political and religious protesters in various countries may now be restrained. The changes won’t harm legitimate research and teaching, because the exemptions I listed above will still apply in those cases. There are no new restrictions on defensive tools. There are no new restrictions on cryptography.
Companies and individuals making software or hardware that will fall under these new rules will now have to go through the process of applying for export licenses, It may also be the case those entities may find their markets reduced. I suspect that it is a small population that will be subject to such a restriction, and for some of them, given their histories, I’m not at all bothered by the idea.
I have seen some analyses that claim that software to jailbreak cellphones might now be controlled. However, if published online without fee (as is often the case), it would be exempt under 734.7. It arguably is a debugging tool, which is also exempt.
I have also seen claims that any technology for patching would fall under these new rules. Legitimate patching doesn’t seek to avoid detection or defeat countermeasures, which are specifically defined as “techniques designed to ensure the safe exertion of code.” Thus, legitimate patching won’t fall within the scope of control.
Jennifer Granick wrote a nice post about the changes. She rhetorically asked at the end whether data loss prevention tools would fall under this new rule. I don’t see how — those tools don’t operate on national grade backbones or index the data they extract. She also posed a question about whether this might hinder research into security vulnerabilities. Given that fundamental research is still exempt under 734.8 as are published results under 734.7, I don’t see the same worry.
The EFF also posted about the proposed rule changes, with some strong statements against them. Again, the concern they stated is about researchers and the tools they use. As I read the EAR and the proposed rule, this is not an issue if the source code for any tools that are exported is published, as per 734.7. The only concern would if the tools were exported and the source code was not publicly available, i.e., private tools exported. I have no idea how often this happens; in my experience, either the tools are published or else they aren’t shared at all, and neither case runs afoul of the rule. The EFF post also tosses up fuzzing, vulnerability reporting, and jailbreaking as possible problems. Fuzzing tools might possibly be a problem under a strict interpretation of the rules, but the research and publication exemptions would seem to come to the rescue. Jailbreaing I addressed, above. I don’t see how reporting vulnerabilities would be export of technology or software for building or controlling intrusion software, so maybe I don’t understand the point.
At first I was concerned about how this rule might affect research at the university, or the work at companies I know about. As I have gotten further into it, I am less and less worried. it seems that there are very reasonable exceptions in place, and I have yet to see a good example of something we might legitimately want to do that would now be prohibited under these rules.
However, your own reading of the proposed rule changes may differ from mine. If so, note the difference in comment to this essay and I’ll either respond privately or post your comment. Of course, commenting here won’t affect the rule! If you want to do that, you should use the formal comment mechanism listed in the Federal Register notice, on or before July 20, 2015.
Update July 17: The BIS has an (evolving) FAQ on the changes posted online. It makes clear the exemptions I described, above. The regulations only cover tools specially designed to design, install, or communicate with intrusion software as they define it. Sharing of vulnerabilities and proof of exploits is not regulated. Disclosing vulnerabilities is not regulated so long as the sharing does not include tools or technologies to install or operate the exploits.
As per the two blog posts I cite above

Chair, ACM US Public Policy Council (USACM)†
About 20 years ago, there was a heated debate in the US about giving the government mandatory access to encrypted content via mandatory key escrow. The FBI and other government officials predicted all sorts of gloom and doom if it didn’t happen, including that it would prevent them from fighting crime, especially terrorists, child pornographers, and drug dealers. Various attempts were made to legislate access, including forced key escrow encryption (the “Clipper Chip”). Those efforts didn’t come to pass because eventually enough sensible — and technically literate — people spoke up. Additionally, the economic realities also made it clear that people weren’t knowingly going to buy equipment with government backdoors built in.
Fast forward to today. In the intervening two decades, the forces of darkness did not overtake us as a result of no restrictions on encryption. Yes, there were some terrorist incidents, but either there was no encryption involved that made any difference (e.g., the Boston Marathon bombing), or there was plenty of other evidence but it was never used to prevent anything (e.g., the 9/11 tragedy). Drug dealers have not taken over the country (unless you consider Starbucks coffee a narcotic). Authorities are still catching and prosecuting criminals, including pedophiles and spies. Notably, even people who are using encryption in furtherance of criminal enterprises, such as Ross “Dread Pirate Roberts” Ulbricht, are being arrested and convicted. In all these years, the FBI has yet to point to anything significant where the use of encryption frustrated their investigations. The doomsayers of the mid-1990s were quite clearly wrong.
However, now in 2015 we again have government officials raising a hue and cry that civilization will be overrun, and law enforcement will be rendered powerless unless we pass laws mandating that back doors and known weaknesses be put into encryption on everything from cell phones to email. These arguments have a strong flavor of déjà vu for those of us who were part of the discussion in the 90s. They are even more troubling now, given the scope of government eavesdropping, espionage, and massive data thefts: arguably, encryption is more needed now that it was 20 years ago.
USACM, the Public Policy Council of the ACM, is currently discussing this issue — again. As a group, we made statements against the proposals 20 years ago. (See, for instance, the USACM and IEEE joint letter to Senator McCain in 1997). The arguments in favor of weakening encryption are as specious now as they were 20 years ago; here are a few reasons why:
There are other reasons, too, including cost, impact on innovation, and more. The essay below provides more rationale. Experts and organizations in the field have recently weighed in on this issue, and (as one of the individuals, and as chair of one of the organizations) I expect we will continue to do so.
With all that as a backdrop, I was reminded of an essay on this topic area by one of USACM’s leaders. It was originally given as a conference address two decades ago, then published in several places, including on the EPIC webpage of information about the 1990s anti-escrow battle. The essay is notable both because it was written by someone with experience in Federal criminal prosecution, and because it is still applicable, almost without change, in today’s debate. Perhaps in 20 more years this will be reprinted yet again, as once more memories dim of the arguments made against government-mandated surveillance capabilities. It is worth reading, and remembering.
by Andrew Grosso, Esq.
Chair, USACM Committee on Law
(This article is a revised version of a talk given by the author at the 1996 RSA Data Security Conference, held in San Francisco, California. Mr. Grosso is a former federal prosecutor who now has his own law practice in Washington, D.C. His e-mail address is agrosso@acm.org.)
I would like to start by telling a war story. Some years ago, while I was an Assistant U.S. Attorney, I was asked to try a case which had been indicted by one of my colleagues. For reasons which will become clear, I refer to this case as “the Dank case.”
The defendant was charged with carrying a shotgun. This might not seem so serious, but the defendant had a prior record. In fact, he had six prior convictions, three of which were considered violent felonies. Because of that, this defendant was facing a mandatory fifteen years imprisonment, without parole. Clearly, he needed an explanation for why he was found in a park at night carrying a shotgun. He came up with one.
The defendant claimed that another person, called “Dank,” forced him to carry the gun. “Dank,” it seems, came up to him in the park, put the shotgun in his hands, and then pulled out a handgun and put the handgun to the defendant’s head. “Dank” then forced the defendant to walk from one end of the park to other, carrying this shotgun. When the police showed up, “Dank” ran away, leaving the defendant holding the bag, or, in this case, the shotgun.
The jurors chose not to believe the defendant’s story, although they spent more time considering it than I would like to admit. After the trial, the defendant’s story became known in my office as “the Dank defense.” As for myself, I referred to it as “the devil made me do it.”
I tell you this story because it reminds me of the federal government’s efforts to justify domestic control of encryption. Instead, of “Dank,” it has become, “drug dealers made me do it;” or “terrorists made me do it;” or “crypto anarchists made me do it.” There is as much of a rationale basis behind these claims as there was behind my defendant’s story of “Dank.” Let us examine some of the arguments the government has advanced.
It is said that wiretapping is indispensable to law enforcement. This is not the case. Many complex and difficult criminal investigations have been successfully concluded, and successfully argued to a jury, where no audio tapes existed of the defendants incriminating themselves. Of those significant cases, cited by the government, where audio tapes have proved invaluable, such as in the John Gotti trial, the tapes have been made through means of electronic surveillance other than wire tapping, for example, through the use of consensual monitoring or room bugs. The unfettered use of domestic encryption could have no effect on such surveillance.
It is also said that wiretapping is necessary to prevent crimes. This, also, is not the case. In order to obtain a court order for a wire tap, the government must first possess probable cause that a crime is being planned or is in progress. If the government has such probable cause concerning a crime yet in the planning stages, and has sufficient detail about the plan to tap an individual’s telephone, then the government almost always has enough probable cause to prevent the crime from being committed. The advantage which the government gains by use of a wiretap is the chance to obtain additional evidence which can later be used to convict the conspirators or perpetrators. Although such convictions are desirable, they must not be confused with the ability to prevent the crime.
The value of mandating key escrow encryption is further eroded by the availability of super encryption, that is, using an additional encryption where the key is not available to the government. True, the government’s mandate would make such additional encryption illegal; however the deterrence effect of such legislation is dubious at best. An individual planning a terrorist act, or engaging in significant drug importation, will be little deterred by prohibitions on the means for encoding his telephone conversations. The result is that significant crimes will not be affected or discouraged.
In a similar vein, the most recent estimates of the national cost for implementing the Digital Telephony law, which requires that commercial telecommunications companies wiretap our nation’s communications network for the government’s benefit, is approximately three billion dollars. Three billion dollars will buy an enormous number of police man hours, officer training, and crime fighting equipment. It is difficult to see that this amount of money, by being spent on wire tapping the nation, is being spent most advantageously with regard to law enforcement’s needs.
Finally, the extent of the federal government’s ability to legislate in this area is limited. Legislation for the domestic control of encryption must be based upon the commerce clause of the U.S. Constitution. That clause would not prohibit an individual in, say, the state of California from purchasing an encryption package manufactured in California, and using that package to encode data on the hard drive of his computer, also located in California. It is highly questionable whether the commerce clause would prohibit the in-state use of an encryption package which had been obtained from out of state, where all the encryption is done in-state and the encrypted data is maintained in- state. Such being the case, the value of domestic control of encryption to law enforcement is doubtful.
Now let us turn to the disadvantages of domestic control of encryption. Intentionally or not, such control would shift the balance which exists between the individual and the state. The individual would no longer be free to conduct his personal life, or his business, free from the risk that the government may be watching every move. More to the point, the individual would be told that he would no longer be allowed to even try to conduct his life in such a manner. Under our constitution, it has never been the case that the state had the right to evidence in a criminal investigation. Rather, under our constitution, the state has the right to pursue such evidence. The distinction is crucial: it is the difference between the operation of a free society, and the operation of a totalitarian state.
Our constitution is based upon the concept of ordered liberty. That is, there is a balance between law and order, on the one hand, and the liberty of the individual on the other. This is clearly seen in our country’s bill of rights, and the constitutional protections afforded our accused: evidence improperly obtained is suppressed; there is a ban on the use of involuntary custodial interrogation, including torture, and any questioning of the accused without a lawyer; we require unanimous verdicts for convictions; and double jeopardy and bills of attainder are prohibited. In other words, our system of government expressly tolerates a certain level of crime and disorder in order to preserve liberty and individuality. It is difficult to conceive that the same constitution which is prepared to let a guilty man go free, rather than admit an illegally seized murder weapon into evidence at trial, can be interpreted to permit whole scale, nationwide, mandatory surveillance of our nation’s telecommunications system for law enforcement purposes. It is impossible that the philosophy upon which our system of government was founded could ever be construed to accept such a regime.
I began this talk with a war story, and I would like to end it with another war story. While a law student, I had the opportunity to study in London for a year. While there, I took one week, and spent it touring the old Soviet Union. The official Soviet tour guide I was assigned was an intelligent woman. As a former Olympic athlete, she had been permitted in the 1960’s to travel to England to compete in international tennis matches. At one point in my tour, she asked me why I was studying in London. I told her that I wanted to learn what it was like to live outside of my own country, so I chose to study in a country where I would have little trouble with the language. I noticed a strange expression on her face as I said this. It was not until my tour was over and I looked back on that conversation that I realized why my answer had resulted in her having that strange look. What I had said to her was that *I* had chosen to go to overseas to study; further, I had said that *I* had chosen *where* to go. That I could make such decisions was a right which she and the fellow citizens did not have. Yes, she had visited England, but it was because her government chose her to go, and it was her government which decided where she should go. In her country, at that time, her people had order, but they had no liberty.
In our country, the domestic control of encryption represents a shift in the balance of our liberties. It is a shift not envisioned by our constitution. If ever to be taken, it must be based upon a better defense than what “Dank,” or law enforcement, can provide.
