Title: How to Search on Encrypted Data

Tuesday September 17th
11:00am 366 WVH

Abstract:
The problem of searching over encrypted data arises often and, most notably, in the design of secure database systems, file systems, cloud storage systems and in the design of cryptographic protocols. Many solutions to this problem have been proposed in the past, including searchable encryption, deterministic encryption, order preserving encryption, functional encryption, oblivious RAMs, secure two-party computation and fully-homomorphic encryption.

In this talk, I will survey the different solutions to the encrypted search problem and discuss their various strengths and limitations, paying particularly close attention to the tradeoffs made between security, efficiency and functionality. I will then present recent advances in the area of searchable encryption and give an overview of the state-of-the art constructions and implementations.
