协同商务与设计环境中的安全体系与技术研究

Research on security architecture and security technologies for collaborative commerce and design environment

为了解决相应的多域、异构和多变等复杂的安全问题,提出了协同商务与设计环境的安全策略,构建了协同商务与设计环境的安全体系,应用用户代理和资源代理提供资源的访问和安全控制,在不改变协同商务与设计环境各安全个体域的访问控制机制的情况下,实现跨异构域的安全资源访问,为协同商务与设计活动提供有效的安全保障,同时为用户提供方便的资源访问手段。最后,给出了支持协同商务与设计环境安全体系的关键技术框架结构。

Collaborative commerce and design environment (CCDE) is characterized by of its numerous users, massive resources and dynamic change. In order to solve security problems coming from multi - domain, heterogeneity and dynamics, the security policies for CCDE were introduced. The security architecture for CCDE was constructed, which employed user proxy and resource proxy to provide resource & security access control. On the premise that the access control mechanism of each individual security domain was not changed in CCDE, secure resource access could be accomplished in cross- heterogeneous domains. The security of collaborative commerce and design activities were guaranteed and at the same time easy use of resource access was provided. At last, the framework of key supporting technologies of CCDE was also introduced.
