Abstract: This paper proposes a new idea that making identity-based cryptography mechanism applies to the wireless Mesh network for the security features and defects，designs IBS-EAP access authentication protocol and IBS-RP roaming authentication protocol，which achieves rapid access，avoides multiple certification，analyzes the security and efficiency of the new protocols，and proves the superiority of the new protocols.It also designs IBS-EAP access authentication protocol which achieves rapid access，and completes mutual authentication based on IBS signature technology.The public key can be received by node identity and the IBS system public parameters，without using complex technology to maintain public key certificates and certificate revocation list CRL.

Key words: identity-based cryptography, wireless Mesh network, security, access authenticate

摘要： 针对无线Mesh网络的特点和安全缺陷，提出将基于身份密码学机制应用到无线Mesh网络的思想，设计了IBS-EAP接入认证协议和IBS-RP漫游认证协议，实现快速接入，避免了多次认证；对新协议进行安全性分析和效率分析，证明了新协议的优越性。设计了IBS-EAP接入认证协议，实现了快速接入的目的，基于IBS签名技术完成双向认证，一个节点的公钥可以通过身份标识和IBS系统的公开参数直接获得，无需采用复杂的技术维护公钥证书和证书撤销列表CRL。
