新一代访问控制技术在web系统中的应用

The application and research of new access conrol method on web system

为了对复杂的web系统资源的访问控制提供一个系统全面的访问控制方法,在对传统访问控制和现代访问控制方法进行分析的基础上提出了使用控制模型.通过UCON的基础模型分析了UCON模型在访问控制的连续性和可变属性两个方面的表现.两个具体的应用实例进一步证实了UCON模型在实际web系统访问控制上体现的优越性.

With the wide application of the Internet, the studies of access control on web system has been one of the emphases of security. The Usage Control （UCON） model is put forward based on the analysis of traditional access control and modern access control to provide a systematic and comprehensive method for the complicated web system. Continuity and mutability are shown by the basic models of UCON. Two examples validate the advantage of UCON in solving the access control problems of web systems.
