Abstract

This thesis focuses on practical aspects of general two-party Secure Function Evaluation (SFE). We give a new SFE protocol that allows free evaluation of XOR gates and is provably secure against semi-honest adversaries in the random oracle model. Furthermore, the extension of SFE to private functions (PF-SFE) using universal circuits (UC) is considered. Based on our new practical UC construction, FairplayPF is implemented as extension of the well-known Fairplay SFE system to demonstrate practicability of UC-based PF-SFE. Also new protocols for SFE and PF-SFE of functions alternatively represented as Ordered Binary Decision Diagram (OBDD) are given.
