摘要
安全多方计算在密码学中拥有相当重要的地位,是近几年国际密码界研究的热点问题.文中主要是对安全双方计算的密钥协商方案中的方案进行了改进,提出了3种改进方案,即使窃听者获得与接收方完全一样的数据,此3种方案都是安全的.
Secure Multiparty Computation protocol is an important area in cryptography.The research of multi-party computation was a subject of great importance in the international cryptographic circle.A key agreement scheme based on secure two-party computation is improved.Three schemes are proposed.It can be proved that even if Eve gets the same data as the receiver,the schemes are still secure.
