The idea of role has been widely applied to solving the authority, responsibility, function and interaction, which are associated with member station in organizations. Access control is a key security issue in distributed collaboration systems. After analyzing corresponding security requirements and the present status of security in distributed collaboration system, this paper presents an extensive role-based access control (ERBAC) architecture based on differentiated domain management. In this architecture, security management is classified into inter-domain one and infra-domain one, whilst, it can integrate new security policies. Based on definition of role permission type, the paper introduces a function of permission type change to make ERBAC architecture flexible. In addition, the authors discuss the methods by which the security can be implemented in an agent-based framework. The practices signify that this system can be flexibly applied various existing policy languages and protocols.
