VIFF is a framework which allows you to specify secure multi-party computations in a clean and easy way. Current features include:

  • arithmetic with shares from Zp or GF(28).
  • secret sharing based on Shamir and pseudo-random secret sharing (PRSS).
  • addition, multiplication, exclusive-or of shares.
  • comparison of secret shared Zp inputs, with secret Zp or GF(28) output.
  • automatic parallel (asynchronous) execution.
  • secure communication using TLS (the successor to SSL).
  • cute mascot :-)
