VIFF: Virtual Ideal Functionality Framework

Virtual Ideal Functionality Framework is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs -- even if some players try to cheat by deviating from the protocol. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs.
