从分析高校图书馆数字化服务入手,引入云计算的理念,探讨高校图书馆云环境下共建共享服务安全模式的实现方式。通过深入研究云计算及用户信息行为,建立一种基于云计算的高校图书馆统一资源服务安全策略管理架构,实现体系化服务大安全管理。对运行机制进行分析,提出云访问控制多安全域统一策略及形式化描述,以提升高校数字化图书馆安全服务能力。
Starting from analyzing the digital service of university library and introducing the concept of cloud computing, this paper discusses how to realize the security mode of building and sharing service under the cloud environment of university library. Through in-depth study of cloud computing and user information behavior, a cloud computing-based unified resource service security policy management framework for university libraries was established to realize systematic service security management. Analyzes the operation mechanism and puts forward the unified strategy and formal description of cloud access control multi-security domain to improve the security service ability of digital library in colleges and universities.
