In multicast communications, where service providers distribute services such as streaming multimedia, distributed databases, and etc., an important issue is to control the access to both the transmitted data and the network resources. This issue becomes more complicated when the multicast communication takes place in a hierarchical organizational structure, such as the military. In this paper, we analyze the multicast security issues and propose a new approach to securing hierarchical multicast communications. Specifically, we specify requirements for developing access control policies in hierarchical multicast communications and propose a model for enforcing such policies. Our approach is based on the well-known role-based access control model. We show that our approach is simple, but yet is very flexible, scalable, and effective in controlling the access to the transmitted data as well as to the shared secret key, used in providing data confidentiality.
