A gateway-oriented password-based authenticated key exchange (GPAKE) scheme allows a client to establish an authenticated session key with a gateway via the help of an authentication server, where the client has pre-shared a password with the server.

This paper proposes an efficient architecture to produce a hierarchical access control scheme for the multicast application environment. The architecture divides the group members into several subgroups with different access rights. In order to enhance the efficiency, the theory of Weil pairing is introduced to present a three party key agreement protocol. The advantages of this scheme are : (1) easy...
