网络图书馆中系统集成与安全认证技术研究

System Integration and Authentication Technology Research on Net-Library

数字图书馆是当前计算机界研究的一个热点 ,本文以“上海市高校网络图书馆”为背景 ,介绍网络图书馆中所采用的系统集成技术和安全认证技术 .首先从系统集成的角度看 ,我们的方案有两个优点 :一是不影响各高校图书馆现有系统的正常运行 ,保持原有系统的独立性 ,在此基础上实现往新系统平滑集成 ;二是面对现实存在的困难情况 ,在软硬件平台异构性的环境中 ,实现良好的互操作、开放性和可扩展性 .其次 ,面对 Internet中“信任 "这一错综复杂的问题 ,我们采用基于 PKI的安全认证技术 ,完成对用户公用密钥的信任和对用户的身份的确认 .

Digital library is research hotspot now in computer fields. This paper presents system integration and authentication technology based on Net Library Among the Universities in Shanghai. From points of system integration, the advantages of this plan are as follows: Firstly, it keeps old systems running independently, not affecting their routine work in the past. Based on the precondition, we integrate them into our current system smoothly. Second, Facing the difficulties in real condition, especially diversity of software and hardware platforms, our system is implemented with perfect interoperation, openness and expansibility. Secondly, We adopt PKI based authentication technology to deal with complicated problems of trust in Internet, by which a user's public key can be trust and a user's identity can be confirmed.
