With the growing needs for and the benefits of sharing resources and information among different organizations, an interoperation framework that automatically integrates policies to facilitate such cross-domain sharing in a secure way is becoming increasingly important. To avoid security breaches, such policies must enforce the policy constraints of the individual domains. Such constraints may include temporal constraints that limit the times when the users can access the resources, and separation of duty (SoD) constraints. Existing interoperation solutions do not address such cross-domain temporal access control and SoDs requirements. In this paper, we propose a role-based framework to facilitate secure interoperation among multiple domains by ensuring the enforcement of temporal and SoD constraints of individual domains. To support interoperation, we do not modify the internal policies, as most of the current approaches do. We present experimental results to demonstrate our proposed framework is effective and easily realizable. © 2011 IEEE.
