CS Colloquium: Elette Boyle (Technion Israel Institute of Technology) - Large-Scale Secure Computation

Speaker: Elette Boyle, Technion Israel Institute of Technology

Talk Title: Large-Scale Secure Computation

Series: CS Colloquium

Abstract: The ability to collect and process large data sets has unlocked exciting new technological and research discoveries. Unfortunately, in several important applications, it is not possible to leverage the full extent of collected data, when information consists of sensitive data sets held by individual agents who are either unable or unwilling to share the data itself (e.g., patients' medical information gathered by different medical studies).

A promising approach to enable data sharing within these scenarios is to make use of cryptographic tools such as secure multi-party computation (MPC). MPC protocols provide a means for mutually untrusting parties to jointly evaluate a global function f over their secret inputs, while guaranteeing that no information is revealed beyond the function output.

However, despite great progress in MPC techniques in the last three decades, the surrounding world of data aggregation and computation has leapt even more rapidly forward. For example, nearly all existing MPC protocols require each party to store information comparable to the {\em total} combined data, and evaluate the desired function via a {\em boolean circuit} representation. When the number of parties and size of data is large, or when the functions to be computed are "lightweight" (e.g. touching only small portions of the data), these limitations completely obliterate feasibility of MPC as a solution.

In this talk, I will introduce a new class of techniques yielding MPC protocols whose parameters scale to the modern regime of massive data.
