Trust-based dynamic access control in Web Services
Web Services中基于信任的动态访问控制*

In Web Services system, dynamic nondeterministic user behavior makes the present access control model difficult to control user malicious behavior. So this paper proposed an access control model based on trust, which combined the security assertion markup language and extensible access control markup language, and adopted a confidence computing method based on loyalty as well. The result of simulation shows that access control method, which effectively prevents malicious behavior to realize dynamic access control, is universal, flexible and extensible.
