摘　　要：不同网络同时维护多套认证设施会大幅降低异构融合网络的接入效率,传统接入认证方法中的短板效应也会降低融合网络中的安全性能,为此在异构融合通信网络环境下,提出可信接入安全认证方法。以安全认证过程的信息流走向为依据,搭建网络可信接入安全认证模型,在认证模型下,从信道、网络容量和网络服务质量三个方面,设定通信网络的允许接入条件。通过用户位置预测、用户身份隐替标识和用户签名认证三个步骤实现用户身份的认证,设立安全认证密钥分配协议作为统一用户标识的认证方案。仿真测试结果表明,可信接入安全认证方法的平均安全系数为98.5%,相比于传统的认证方法安全性提高了7%,说明上述方法可以实现网络的安全可信接入,保障用户的安全性。Due to the short board effect,traditional access authentication methods reduce the security performance of heterogeneous convergence network.Therefore,a trusted access security authentication method in the environment of heterogeneous fusion communication network was proposed.Based on the trend of information flow during the security authentication,a network trusted access security authentication model was built.Based on the authentication model,the permissible access condition of communication network was determined from three aspects:channel,network capacity and network service quality.Then,the authentication of user identity was realized through three steps:user location prediction,user identity covert identification and user signature authentication.Finally,the distribution protocol of secure authentication key was set as the authentication scheme of unified user identity.Simulation results show that the average security coefficient of trusted access security authentication method is 98.5%,which is 7%higher than the traditional authentication method,so the proposed method can achieve secure and trusted access to the network and guarantee the security.
