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 and non-repudiation of network communication data, and it will play a greater role with the development of network technology and penetration.The paper introduced the basic theory of digital signature： public key system, a one-way hash function, CA and certificate and designed a digital signature program with a specific function-both of the transistor and receiver non-repudiation signature program.
