An Extended Identity Based Authenticated Asymmetric Group Key Agreement Protocol
In this paper, the authors proposed a new asymmetric group key agreement protocol allowing a set of users to negotiate a common encryption key accessible by any users and each user holds their respective decryption key. This enables the confidential message communication among group users and grants any outsider to send message to the group. In this paper, an authenticated asymmetric group key agreement protocol is proposed, which offers security against active as well as passive attacks. Proposed protocol uses broadcast encryption mechanism without relying on the trusted dealer to distribute the secret key.
