A New Wireless Mesh Network Authentication Scheme Based on Threshold Method

摘要

Access authentication is one of the secure issues which are eager to be resolved in wireless mesh networking. This paper proposes new wireless mesh network authentication architecture based on threshold signature technology. First, we point out the weakness of single authentication server and the security risks of traditional AAA authentication method. Then we design a new authentication system with multiple authentication servers: N authentication servers (AS) compose a authentication server group, only if t or more than t authentication servers allow a certain mobile subscriber require to access to the network, this subscriber can join in the network. This approach solves the deficiencies of single authentication server and guarantees the whole security of the authentication systems in mesh network.
