公平的安全多方计算协议
Secure Multiparty Computation Protocol with Fairness
摘要
Abstract
In secure multiparty computation, fairness is an important property, which guarantees all parties receive their outputs. However, it is impossible to achieve complete fairness without an honest majority. To overcome this impossibility, in malicious model, a fair and secure multiparty computation protocol for general functionality is proposed based on garbled circuits and by using commitment and cut and choose technology. Analysis results indicate the agreement guarantees security and fairness when honest party is t≥4.关键词
