In secure Multi Party Computation (MPC), a number of players each supply a private input and then compute an agreed function on these inputs securely, i.e., even if an adversary corrupts some of the players, honest players obtain correct results, and the intended outputs is the only new information released about the inputs. Several general feasibility results for MPC are known, for instance, given secure point to point channels, any function can be computed securely against an honest but curious adversary corrupting any minority of the players, and securely against a malicious adversary corrupting less than one third of the players.
