Stateless Key Distribution for Secure Intra and Inter-Group Multicast in Mobile Wireless Network
Source: Reed Elsevier
Group communication has become an important component in wireless networks. In this paper, the authors focus on the environments in which multiple groups coexist in the system, and both intra and inter-group multicast traffic must be protected by secret keys. They propose a mechanism that integrates polynomials with stateless secret updates to achieve personal key share distribution and efficient key refreshment during group changes. The proposed mechanism distributes keys via true broadcast.
