Abstract

Multicast is an efficient technique for delivering data to a large group of users in multimedia applications such as Internet stock quotes Internet radio audiomusic delivery video surveillance etc In order to offer forward and backward secrecy for multicast applications the data encryption key DEK has to be changed whenever a user joins or leaves the system The delay introduced by such user joinleave processes can be high when the user pool is large There are many group key management solutions to implement the group rekeying in secure multicast communication These schemes use a centralized server to generate store and distribute the group keys If not managed properly these rekey messages which inform the key change would consume a large amount of rekeying cost and incur huge delay newline%%%Reference p.164-176
