数字签名技术在电子商务系统中的应用

Application of digital signature in E-commerce

随着Internet的快速发展,对电子商务信息安全提出了更高的要求,而数字签名技术在保证数据的完整性、私有性和不可抵赖性方面起着极为重要的作用。本文提出了一种基于公钥加密的数字签名技术。通过这种方式,不仅实现了数字签名,而且还能保证传输数据的机密性,给出了一个用Java语言实现的具体数字签名实验系统。

With the development of Intemet, digital signature becomes more and more important for the electronic commerce security because of its data integrity protecting and privacy. This paper is to propose a kind of digital signature based on public key. By this way, both digital signature and defending illegal interpolation and replica- tion of digital products are effectively realized. Finally, a material digital signature system is given with Java.
