Abstract

The Group communication for applications like board-meeting, group discussions and teleconferencing is very critical . Collaborative and distributed application are used for the multi-party interactive computation with Secure group communication . In general, group communications involve over open networks. Group Key Agreement (GKA) is a special key approach to manage a set of secure group keys and group dynamics. To establish a common secret key between the users ,the Conventional and unconventional GKA protocols are used . The members from the group can securely exchange message using the shared key. Asymmetric Group Key Agreement (AGKA) a group of members to establish a public group encryptionkey dynamically providing a different secret decryption key in a identity basedcryptosystem with group communication.

Key words: board-meeting, group discussions
