Abstract: Role Based Access Control (RBAC) and Access Control List (ACL) are the most commonly adopted access control mechanisms in traditional centralized computing environment. Nowadays people frequently work in a highly dynamic and distributed computing environment, in which two or more heterogeneous systems do not share the same security domain. Traditional access control mechanisms that require pre-registration become obsolete. Electronic credential based distributed access control turns out to be the best solution to the current situation. We adopt three kinds of certificates in the solution: attribute certificate, capability certificate and delegation certificate. A language is required to delineate a unified certificate format and to enable administrators to define the trust relationships between e-strangers. We present a policy language, Z-Trust Language, to meet this end. Administrators can finely manage privileges assigned to individual users with the Language. A java program has also been developed as the compliance checker.
