结合云计算和PKI技术,设计了一个数字图书馆系统框架。根据云计算和PKI技术的概念、技术特点,依托Google提供的AppEngine云计算开发平台,集中其技术优势,设计开发了云计算和PKI结合的数字图书馆系统框架并提出框架具体部署方法。运行结果证明:该系统扩展了数字图书馆的信息搜集、分析、检索等能力;实现了证书登录、管理员录入保存图书信息、用户查询图书信息等几大模块,已经拥有了基本的图书馆功能,可以为数字图书馆提供完备的安全保障和可信的网络服务。今后将在此基础上,充分发掘云计算平台AppEngine潜力,逐步实现较全面的数字图书馆系统服务。
Combined with cloud computing and PKI technology, a digital library system framework was designed. According to the concept and technical characteristics of cloud computing and PKI technology, based on the AppEngine cloud computing development platform provided by Google, the technical advantages of the cloud computing and PKI are designed and developed, and a digital library system framework combining cloud computing and PKI is designed and put forward. The running result proves that this system expands the ability of digital library to collect, analyze and retrieve information. It realizes several modules such as certificate login, administrator input and save book information, user inquiry book information and so on, and already possesses basic library functions , Can provide the digital library complete security and credible network services. Based on this, we will make full use of the potential of AppEngine cloud computing platform and gradually realize more comprehensive digital library system services.
