An Improved Secure Authenticated Group Key Agreement Protocol for WMNs

Recently, secure group-oriented applications have grown very rapidly. In order to provide secure group communication, WMNs (Wireless Mesh Network) are required to establish a secret key which is shared with all participants. Recently, Tseng proposed an authenticated group key agreement for regarding mobile networks. This mobile network is an asymmetric wireless network which includes many low-power nodes and several powerful nodes. However, this protocol does not satisfy some important security properties such a simplicit key authentication. In this paper, we conducted ananalysis of Tseng's protocol and propose a secure and efficient group key agreement protocol regarding WMNs which improved upon it. The proposed protocol not only reduces the computational cost, but also meets strong security requirements.
