协同设计系统安全体系结构研究

Research on security structure of collaborative design system

协同设计系统是计算机支持协同工作理论和技术在企业产品开发与设计中的重要应用,为确保系统信息安全这一协同设计系统应用推广的基本前提,以信息系统安全体系结构的基本理论和协同设计系统的系统特性为基础,确定了协同设计系统的安全体系结构至少需要满足系统功能特性、系统分布特性和系统技术特性三个方面的安全需求,并应用面向信息系统的安全视图方法提出了一个由安全功能视图、安全系统视图、安全技术视图以及三种视图之间的关系和之上的约束有机构成的面向分布式应用的协同设计系统的安全体系结构,从总体上指导了协同设计系统的安全设计和实现.

Collaborative design system is an important application of theory and technology of computer-supported collaborative work in the product design of enterprises. Information security of system is the basis of applying and spreading collaborative design system. Based on the fundamental theory of security structure of information system and the characters of collaborative design system, it is determined that the security structure for collaborative design system at least needs to meet the security requirements in the function, distribution and technology characters of the system. Using the security view method for information system, the security structure, which consists of security function view, security system view, security technology view together with the relations and restrictions between them, has been proposed. This security structure faces on the distributed application of collaborative design system, and can be used as an important reference in security design and implementation of collaborative design system.
