Practical Secure Function Evaluation

: This thesis focuses on the practical aspects of general two-party Secure Function Evaluation (SFE). A new SFE protocol that allows free evaluation of XOR gates and is provably secure against semi-honest adversaries in the random oracle model is given. Furthermore, the extension of SFE to private functions (PF-SFE) using universal circuits is considered. Based on a new practical universal circuit construction, FairplayPF is implemented that extends Fairplay, a well known SFE system, with PF-SFE.
