The group security association for secure multicasting

The growth and commercialization of the group-oriented applications on the Internet has triggered a demand for security solutions for group communications. One such solution, secure multicast, is provided because it is available for the efficiency of multicast data delivery. This paper proposes a method of advertising a group security association for secure group communication and defines extensions of SAP (session announcement protocol) and SDP (session description protocol) for the framework. It provides descriptions for group security associations (GSA) for the support of secure multicasting in IP multicast.
