Promise Zero Knowledge and its Applications to Round Optimal MPC
ADVANCES IN CRYPTOLOGY - CRYPTO 2018, PT II, pp. 459-487, 2018.
We devise a new partitioned simulation technique for MPC where the simulator uses different strategies for simulating the view of aborting adversaries and non-aborting adversaries. The protagonist of this technique is a new notion of promise zero knowledge (ZK) where the ZK property only holds against non-aborting verifiers. We show how t...More
