Abstract

With the advent of cloud computing, our view of cryptographic protocols has changed dramatically. In this talk, I will give an overview of some of the newer challenges that we face in cloud cryptography and outline some of the techniques used to solve these problems. In particular, a few questions that I will address are:

1) How can we store sensitive data in the cloud, in an encrypted manner, and yet allow controlled access to certain portions of this data?
2) How can we ensure reliability of data across cloud servers that may be connected by only a low-degree communication network, even when some of the servers may become corrupted?
3) How can users authenticate themselves to the cloud in a user-friendly way?

This talk will assume no prior knowledge of cryptography and is based on works that appear at TCC 2012, ICALP 2010 and STOC 2010.
