Abstract

Today, a large amount of private data resides in the cloud in an encrypted form. There are tremendous benefits of performing computations on this data to extract useful information. Yet, security of encryption seems inimical to this goal.

This raises the following fundamental question: Can the cloud perform general computations on encrypted datasets of unbounded size (without knowing the decryption key)?

My research provides the first positive resolution of this question. In this talk I will describe these new results, and discuss their interplay with other broad questions in cryptography.
