Theory Seminar: Payman Mohassel, University of Calgary - Private Function Evaluation: A General Framework and Efficient Realizations

Abstract:

Private function evaluation (PFE) is a variant of secure multiparty computation wherein the function (circuit) being computed is also considered to be a private input of one of the participants.

In this talk, I will first review the existing solutions for PFE in a variety of settings and identify their shortcomings. Then, I will describe our new framework for designing PFE and show how it allows us to obtain new constructions with better asymptotic and practical efficiency. I will end by pointing out a few directions for future research.
