在分析现有异构无线网络认证方法的优点和不足的基础上,提出一种结合证书公钥和身份公钥的混合认证模型.在该认证模型中,用户与本地认证服务器及外地认证服务器之间的认证采用身份公钥体制,本地认证服务器与外地认证服务器之间采用证书公钥体制.该混合认证模型具有匿名性,可扩展性好,降低了资源消耗,符合异构无线网络的应用需求.安全性分析表明该模型在C-K模型下是安全的.
Based on the analysis of the advantages and disadvantages of existing heterogeneous wireless network authentication methods, this paper proposes a hybrid authentication model that combines the public key of the certificate with the public key of the identity, in which the user and the local authentication server and the foreign authentication server Public key authentication is adopted between the local authentication server and the foreign authentication server.The hybrid authentication model has anonymity, good scalability and low resource consumption, which meets the application requirements of heterogeneous wireless networks The safety analysis shows that the model is safe under the CK model.
