网络采购系统中安全机制的研究与实现

针对网络采购系统中的安全问题，提出了一种网络采购系统安全机制模型，综合应用数字证书与ASP.NET的Forms身份验证相结合的认证技术，以及数据加密和数字签名技术，实现了其安全机制。同时，基于B/S模式下实现加密与数字签名的问题，开发了电子合同加密和数字签名智能客户端程序，为构造安全实用的大型网络采购系统奠定了技术基础。

Research and implementation of security mechanism in electronic procurement system

This paper intended to solve the security problem of electronic procurement system. A model of security mechanism was put forward with the help of comprehensive application of the authentication technique combined with digital certificate and ASP.Net's forms authentication, and of the data encryption technique and the digital signature technique. At the same time, concerning the problems of implementation of encryption and digital signature in B/S mode, this paper developed the electronic contract encryption and digital signature smart client program, and prepared the technical ground for the construction of secure, practical, and big electronic procurement system.
