Project Summary

Analyzed 6 months ago based on code collected 6 months ago.

The Virtual Ideal Functionality Framework (VIFF) 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. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs.
