In wireless mobile Mesh network, mobile terminals are mostly hand-held devices with limited computing ability and memory. Traditional centralized AAA authentication model is inadequate to meet the demand of authentication which is of high security and high-speed calculation. To address the limitation of the single AAA authentication model, this paper proposed an advanced wireless Mesh authentication method with multi-servers based on the threshold theory. In this method, only when there are no less than t authentication servers can the members within Authentication Server Group resume the shared key (K) and carry out the valid authentication process, which can avoid fake attack and can prevent single authentication server from being captured. This protocol has the following characteristics: 1) Achieving two-direction authentication between network and users which makes it possible to decrease the amount of calculation of the hand-held devices; 2) By time-stamp technology the security of the mesh networkreply attack can be prevented effectively to ensure user';s financial security; 3) Adopting multiservers certification method, the frequency of key transmission can be reduced and the computation can be accelerated at the same level of security. In general, the proposed method can meet what demand of wireless mobile Mesh network.
