在容忍任何恶意破坏的纯模型中,我们首次构造了两个圆形信息论(IT)安全多方计算(MPC)协议。在不同的通信模型下,我们的协议在两轮内满足最强可达的安全标准概念,以前,在普通模型中的IT-MPC协议要么需要更多的轮数,要么需要更少的损坏。
We provide the first constructions oftwo roundinformation-theoretic (IT) secure multiparty computation (MPC) protocols in the plain model that tolerate anymalicious corruptions. Our protocols satisfy the strongest achievable standard notions of security in two rounds in different communication models.Previously, IT-MPC protocols in the plain model either required a larger number of rounds, or a smaller minority of corruptions.
