An RBAC Based Policy Enforcement Coordination Model in Internet Environment

摘要

An RBAC (Role Based Access Control) based and policy enforcement coordination (RBPEC) model suitable in Internet environment is described. Coordination deals with the interaction between different agents and also between agents and surrounding environments. A set of agents interacting with each other for a common global system task constitutes a coordination group. Coordination is combined with access control in RBPEC model. Role based access control is introduced for security concerns. Coordination policy is enforced in a distributed manner. The model has two advantages of being secure and scalable.
