Global Authentication Using Public Key Certificates In an Object-Oriented Distributed System

Sep 22, 1995


Virtually every financial corporation in America is planning on implementing some form of Digital Cash or Digital Money. David Chaum and a myriad of other researchers have come up with a plethora of cryptographic protocols, each with a set of limitations and problems. A authentication service intended for modern object-oriented distributed systems in an open network environment should be not only reliable and secure, but also be efficient, portable, self-contained and scalable. Previous works in this field have been focussing on the design to deal with distributed management of trust relationships in arbitrarily large networks with multiple, mutually suspicious jurisdictional authorities. The SPX, in particular, combines the Public Key Certification with the DES (Data Encryption Standard) to provide the run-time environment enabling applications to mutually authenticate on the basis of a global principal identity.
The focus of our work is the implementation of a security system for the Renaissance OOD system based on the SPX model. The talk will cover the SPX model, optimization of the SPX (such as public key caching), and related works such as PGP and Kerberos.
