Abstract
A computer-implemented method, computerized apparatus and computer program product for supporting fairness in secure computations. A trusted execution platform with remote attestation (“enclave”) is provided to each of a plurality of participants. An authenticated public ledger accessible by all participants is also provided. Each of the enclaves is configured for obtaining at least a portion of an input to a function for computing a joint secret output, complementing the input by obtaining any remainder portion(s) thereof from one or more other enclaves, and, responsive to obtaining an indication from the ledger that the output can be computed by each of the enclaves, providing to the owner participant the output computed using the function and input. At least one of the enclaves is further configured for providing the indication to the ledger responsive to obtaining knowledge that the output can be computed by each of the enclaves.
