Abstract：Ad hoc Networks is characteristic of limited energy and memory. A novel entity authentication scheme based on HuffMHT for Ad hoc Networks is proposed to solve such problems. This method using the concept of HuffMHT can obtain an effective safe strategy. At the same time, symmetrical key algorithm and public key algorithm are just combined to reduce the authentication delay effectively and increase the network lifetime and enhances the security of the networks. Moreover, when clustering head and HuffMHT is built up in the Ad hoc Networks, Power-consumption-least algorithm are designed and Christofides algorithm are used in this paper, respectively, distance which notes effectively transmit signal together are reduced, the power which notes consume is debased, the network lifetime is increased.
