Efficient and Security Protocol for Group Key Distributed in Mobile Network
Jianming Zhu · Jisuanji yingyong yanjiu · 2007
Group communication in mobile networks is often dynamic and thus requires efficient and automated secure group management and seamless combination of secure groups with distributed applications running upon them.Existing approaches to secure group communication cannot satisfy these requirements.In this paper,a new protocol for secure group communication is presented.It is based on the concept of one-way accumulators.The protocol does not require each node to maintain a membership list and efficiently handles dynamic membership events(nodes remove and join).
