Explore a comprehensive analysis of broadcast-optimal two-round Secure Multiparty Computation (MPC) in this 22-minute conference talk presented at Eurocrypt 2020. Delve into the paper by Ran Cohen, Juan Garay, and Vassilis Zikas, examining various aspects of security with abort and the minimum rounds required for MPC. Investigate impossibility results, lower bounds, and feasibility outcomes for 2-round MPC without broadcast. Gain insights into the structure of 2-round protocols, proof ideas, and the implications of unanimous and identifiable abort. Enhance your understanding of this critical topic in cryptography and its practical applications.
