电子交易系统中文本安全传输方案的研究

Research on safely transmitting of electronic text in E-commerce system

为了提高电子交易系统中文本传输的可靠、快速、保密、安全性能,本文提出了一套基于SET协议、采用散列函数SHA计算消息摘要、将椭圆曲线公钥算法和AES私钥算法相结合,实现对电子文本加密、解密、签名及验证等功能的解决方案。文中阐述了从算法设计到方案实现的具体过程。

In order to improve the reliability,high transmit rate,secrecy and safety of electronic text transmitted in electronic commerce system,based on the SET protocol,a set of solutions scheme are provided in this paper,which use scattered function SHA to calculate the abstract of message and combine the Curve common key algorithm with AES private key algorithm.The functions such as encrypt,decipher,digital signature and verifying of electronic text are realized by the solutions scheme.This paper also gives the particular design process from the algorithm design to the scheme realization.
