Abstract: There are three major drawbacks of a centralized security administration in distributed systems: It creates a bottleneck for request handling, it tends to enforce homogeneous security structures in heterogeneous user groups and organizations, and it is a weak point in terms of security attacks, reliability, and fault tolerance. In this paper we introduce a distributed authorization concept which is based on a modular authorization language for supporting cooperating distributed authorization... (Update)
