Traditional centralized AAA authentication model is prone to suffer from service paralysis due to the DoS(Denial of Service) attack or malicious destroy in wireless Mesh network.To salve this isswe,the scheme of threshold authentication with multi-servers is proposed based on the Asmuth-Bloom threshold technology,then wireless access and authentication flow are designed and analyzed.Only the members within Authentication Server Group(ASG) can carry out the valid authentication process,moreover,only t or more than t authentication servers can resume the shared key K,which can avoid the fraudulent attack and can prevent single authentication server from being captured.Analysis result shows that,the validity of authemtication mechanism can be guaranteed and the security of system also can be enhanced by the designed threshold authentication systme,our novel idea provides an effective solution to access authentication in wireless Mesh network and has better applied and referenced value.
