摘要
本文针对通用数字签名存在着收方可能否认收到报文的不足之处，在详细分析讨论通用数字签名过程的基础上，提出了一种收方不可否认的数字签名方法。该方法采用传统密钥加密的算法与公开密钥加密的算法相结合的密码体制。
In this paper, the communication process of ordinary digital signature is discussed. The defect of the ordinary digital signature is that the receiver may deny recevied communication message and no anyway to restrict it. Therefore , based on the cryptosystem which combine conventional with public-key, a necessary methode of digital signature that recever can not deny is proposed in this paper.
