Secure Multiparty Computation SPDZ concrete efficiency
2019/1/29
Secure multiparty computation allows a set of mutually distrusting parties to securely compute a function of their private inputs, revealing only the output, even if some of the parties are corrupt. R...
We present a modification to the ZKPoKs used in the HighGear offline protocol for the SPDZ Multi-Party Computation protocol. This modification allows us to both increase the security of the underlying...
