Abstract:
Access control to ensure secure interoperation in multidomain environments is a crucial challenge. A multidomain environment can be categorized as tightly-coupled or loosely-coupled. The specific access control challenges in loosely-coupled environments have not been studied adequately in the literature. In this paper, we analyze the access control challenges specific to loosely-coupled environments. Based on our analysis, we propose a decentralized secure interoperation framework for loosely-coupled environments based on Role Based Access Control (RBAC). We believe our work takes the first step towards a more complete secure interoperation solution for loosely-coupled environment.
