A method is provided for secure function evaluation. The disclosed method is performed by a garbled circuit evaluator for the transfer of private information, and comprises receiving from a constructor (i) s garbled circuits (GCs), wherein each of the GCs having a plurality of input wires; and (ii) commitments for each of the input wires, wherein the commitments comprise s2 pair-wise cryptographic bindings of wire garblings of each given wire in the s GCs; requesting the constructor to reveal a selected check-set of s/2 of the s GCs; and verifying that the check-set was properly constructed using less than all of the commitments.
