A Study on Various Cryptographic Key Management and Distribution System in Secure Multicast Communications

Many emerging web and Internet applications are based on group communication model. In the Internet, multicast has been used successfully to provide an efficient, best-effort delivery service from a sender to a large group of receivers. Thus, securing group communication (i.e., providing confidentiality, authenticity, and integrity of messages delivered between group members) becomes an important Internet design issue. This paper presents a comprehensive summary of recent works addressing the number of scalable approaches which have been proposed for Key Distribution in Secure Multicast Communication.
