Resilient interval based contributory re key agreement with efficient authentication

Abstract

With the explosive growth of internet and web applications many newlineemerging grouporiented distributed applications such as tele videoconferencing newlineand multiplayer games are based on group communication newlinemodel that need security services such as privacy and data integrity To newlineprovide this it is crucial that members of the group share a symmetric key newlinecalled group key which is known only to group users The group key can be newlineused for encrypting data between group members Hence a secure distributed newlinegroup key agreement is required to establish and authenticate a common newlinegroup key for secure and private communication newline newline
