“…In this approach, every domain must expose its access control policies all to the mediator, while others proposed a decentralized policy or mediator-free scheme for secure interoperation because they considered the mediator as a bottleneck that could provide information of every domain. Meanwhile, domains may occasionally contain confidential information that should not be exposed [3,27,34].…”

Distributed multiple organizations interact with each other. If the domains employ role-based access control, one method for interaction between domains is role-mapping. However, it may violate constraints in the domains such as role hierarchy, separation of duty, and cardinality. Therefore, autonomy of the domains is lost. This paper proposes secure interoperation in multidomain environments. For this purpose, a cross-domain is created by foreign permission assignment. In an effort to maintain the autonomy of every domain, several rules are defined formally. Then, a decentralized scheme is used to provide permission mapping between domains. At the next stage, the proposed crossdomain is specified using Alloy, the first logic language. Subsequently, validity of the rules is analyzed through Alloy analyzer.
