Anonymous Authentication Scheme Based on Proxy Group Signature for Wireless MESH Network

Abstract

Wireless MESH Network (WMN) has become an important technology and has been widely deployed due to its simplicity, low cost, and flexibility in implementation. WMN is a wireless multi-hop network, therefore the privacy protection is extremely important. This paper proposes an anonymous access authentication scheme based on the proxy group signature. The scheme completely protects user's privacy during authentication. In order to improve the efficiency of our scheme, we further adopt certificate-based signature mechanism to design a highly efficient handover authentication protocol. Finally, we show the security analysis of our scheme.
