Real-time updating model of access control policies and its implementation
Zhu Hong-wei · Journal of Computer Applications · 2007
Dynamic environments pose new challenges to access control.In order to guarantee the security of information system in dynamic environment,the needs for real-time update of access control policies rise while the policies are in effect and enforcing the changes immediately.Simple concurrent control algorithms for real-time update of access control policy were given in the model.The model and algorithms are useful for concurrent environment in which multiple subjects' access and modify data and access control policies,while the policies are in effect.
