信息安全传输始终是网络技术发展中的焦点问题之一，而在电子商务随着Ｉｎｔｅｒｎｅｔ的发展进入实用化阶段之后，这一矛盾变得尤为突出，综合应用多种安全传输技术的电子商务模型已成为解决这一问题的关键．研究了现有的电子商务模型和协议，讨论了实现信息安全传输的基本要求，包括身份认证体系、信息的私密性、完整性和不可否认性．并根据电子商务的典型模型，结合以上要求，对一种信息安全传输模型进行了描述和分析 Information security transmission is always one of the most important issues in the development of network technology. However, this contradiction has become more prominent after the development of e-commerce as the Internet has entered a practical stage. The e-commerce model that comprehensively uses a variety of secure transmission technologies has been adopted Become the key to solve this problem. The existing e-commerce models and protocols are studied. The basic requirements for the secure transmission of information are discussed, including the authentication system, the privacy, integrity and non-repudiation of information. According to the typical model of e-commerce, combined with the above requirements, an information security transfer model is described and analyzed
