我们提供了新的两轮多方安全计算(MPC)协议在不诚实的多数设置假设两轮不经意传输(OT)存在的最小假设。如果假设的两轮OT协议对半诚实的对手是安全的(在普通模型中),那么我们的两轮MPC协议也是如此。类似地,如果假设的两轮OT协议对恶意对手是安全的(在公共随机/参考字符串模型中),那么我们的两轮MPC协议也是如此。以前,两轮MPC协议仅在相对较强的计算假设下才已知。
We provide new two-round multiparty secure computation (MPC) protocols in the dishonest majority setting assuming the minimal assumption that two-round oblivious transfer (OT) exists. If the assumed two-round OT protocol is secure against semi-honest adversaries (in the plain model) then so is our two-round MPC protocol. Similarly, if the assumed two-round OT protocol is secure against malicious adversaries (in the common random/reference string model) then so is our two-round MPC protocol. Previously, two-round MPC protocols were only known under relatively stronger computational assumptions.
