基于CPK的电子文档安全管理系统的设计与实现

摘要

To realize the security of electronic document management, a design scheme of the safety management based on combined public key (CPK) authentication technology is proposed. First, the goal is clear about the secure electronic document access safely and sharing, a model of the electronic document security management system based on CPK authentication technology is constructed, then the basic principles of operation of the system is described to determine the system main function modules. Finally, make use of CPK authentication technology to achieve the system' s user identity authentication, and at the process of document secure transmission signature and verification, and user authorization, and other major functions. System through testing, operating normally, shows that the scheme is feasible.%为了实现电子文档的安全管理,提出了一种基于CPK认证技术的电子文档安全管理设计方案.明确电子文档的目标是安全访问与共享,在此基础上建立了基于CPK认证技术的电子文档安全管理系统设计模型,阐述了系统运行基本原理,从而确定系统主要功能模块.应用CPK认证技术实现了系统的用户身份认证、电子文档传输过程中的签名和验证、用户授权等主要功能.通过系统测试结果表明,该系统运行正常,验证了设计方案的可行性.
