Security of information systems is a problem chronic, the arrival of cloud computing as a new computing model, feeds the difficulty of implementing effective solutions. Thus more research is currently focused on data security in the cloud, and especially the issue of confidentiality. In this paper, the authors propose a new protocol access control for complex, heterogeneous, interoperable, and distributed systems in the context of Cloud Computing : Multi-TrustOrBAC (Multi-Organization - Trust Based Access Control). This protocol allows a TTP Trust Tierd Party to force users belonging to several organizations to cooperate to meet the security policies defined independently by them.
