Due to the network topology of an ad hoc network changes frequently and unpredictable, the security of multicast routing becomes more challenging than the traditional networks. In this paper, we describes a dynamic multicast height balanced group key agreement that allows a user in a multicast group to dynamically compose the group key and securely deliver multicast data for a multicast source to the other multicast group users in wireless ad hoc networks. The proposed hierarchical structure partitions the group members into location based clusters, capable of reducing the cost of communication and key management when member joins or leave networks. Moreover, based on the Diffie-Hellman key management, the proposed scheme not only provides efficient and rapid dynamic group key reconstructions and secure multicast data transmissions, but also fits the robustness of the wireless networks and lowers overhead costs of security management. ? 2010 IEEE.
