接收方不可抵赖的数字签名方案

数字签名作为一项重要的数据安全技术,在保证网络通信数据的完整性、保密性和不可抵赖性方面发挥着重要的作用,并且随着网络技术的发展和普及,将会发挥更大的作用,该文首先介绍数字签名的理论基础:公开密钥体制、单向散列函数、CA机构和证书,然后针对特定的应用场合,设计出具有特定功能的数字签名方案——双方均不可抵赖的数字签名方案。

A Specific Function-both of the Transistor and Receiver Non-repudiation Signature Program

As an important technology of data security,digital signature play an important part in ensuring the integrity,confidentiality andnon-repudiation of network communication data,and it will play a greater role with the development of network technology and penetra-tion.The paper introduced the basic theory of digital signature: public key system,a one-way hash function,CA and certificate and de-signed a digital signature program with a specific function-both of the transistor and receiver non-repudiation signature program.
