Access security is the key obstacle of the rapid popularization of wireless mesh network (WMN). We suggest the proxy\ngroup signature scheme based on identity in this paper. This scheme is combined with proxy group signature and\nidentity-based group signature, based on designated hierarchical proxy architecture for WMN. An anonymous mutual\nauthentication scheme is thus achieved, which not only simplifies the complex management of PKI but also\nguarantees anonymous authentication and owns high handover authentication efficiency. Performance and security\nanalysis show that the scheme in this paper is efficient and resilient to a series of security and anonymity attacks.
