Abstract

Message passing from one source to another has become a key for many upcoming technologies. This is already achieved by introduction of topics of KEYS, AUTHENTICATIONS etc. Secret key transfer is being done presently by using mutually trusted key generation centre (KGS). By this selection of session key by which encryption is done for information passing is selected. This paper discusses about the advancement of this technology by extending this service to group instead of a single key. The whole group with authenticated users can access the information. The proposed protocol considers the heterogeneity of the peer resources as QOS factor in key generation phase and shared key mechanism as primary process to achieve security in group key sharing.
