Secure interaction between trusted-domains is a major problem on network security. Combining with the advantages of role-based access control (RBAC) and the existing authentication technique on crossing the trusted-domain, this paper proposes a privilege management model on crossing the trusted-domains (PMCT) which is suitable for large scale distributed network. Role recommending policy and unilateral...
The efficient authorization is the precondition of implementing access control. Traditional access control technology which lacks dynamic authorization mechanism focuses on the beforehand authorization process. Based on usage control (UCON) which is new access control technology, this paper proposes a role-based dynamic authorization model. This model extends RBAC by introducing elements of UCON such...
