This event is part of the CyLab Distinguished Seminar Series.

Abstract

In this talk, I will survey a number of cryptographic techniques that increase user privacy when storing and computing on data in a cloud. I will first describe various vulnerabilities that exist and are not protected by standard encryption and authentication mechanisms. I will then describe several techniques to counteract these risks --especially in the case of a malicious or negligent cloud provider, or an insider threat. The talk will cover notions of ORAM, GRAM, MPC, PIR and searching on encrypted data, as well as recent theoretical advances in these important research areas.

The talk will be self-contained and accessible to the general audience.
