摘要
针对通用数字签名方法中存在的收方可以否认收到报文的缺陷,采用传统加密与公开密钥加密算法相结合的密码体制,并且引入了关键字集合。提出了一种更完善的不需要第三方的收方不可否认的数字签名方法。
In this paper the communication processes of ordinary digital signature is discussed. The defect of the ordinary digital signature is that ,the receiver may deny received communication message and no anyway to restrict it. Therefor based on the cryptosystem which combines conventional ,cryptosystem with public-key and adds a key-word set a better method of digital signature that receiver can not deny is proposed in this paper.
