提出了角色授权协同及其序关系一致性分析和模拟的时间Petri网方法.

Abstract

Role authorization constraint is one of focal points of RBAC research.It is a difficult problem to effectively represent the authorization and activation order constraints of multiple roles.Novel role authorization coordination relations were presented and coordination order relations such that existing role relation concepts are expanded.It is able to make RBAC represent complex order constraints when granting or activating multiple roles.The new Petri Net to analyze and simulate the consistence of role authorization coordination as well as its order relation is proposed.
