A framework for secure multi-party computation (SMPC)

Project description

The Virtual Ideal Functionality Framework is a framework for doing secure multi-party computations (SMPC). Features include:

  • secret sharing based on standard Shamir and pseudo-random secret sharing (PRSS).
  • arithmetic with shares from Zp or GF(2^8): addition, multiplication, exclusive-or.
  • two comparison protocols which compare secret shared Zp inputs, with secret GF(2^8) or Zp output.
  • reliable Bracha broadcast secure against active adversaries.
  • computations with any number of players for which an honest majority can be found.

All operations are automatically scheduled to run in parallel meaning that an operation starts as soon as the operands are ready.
