摘　　要：针对传统认证算法容易将属性安全数据当成危险数据进行隔离,影响用户数据处理效率的问题,提出PKI技术的用户身份数据转发认证算法。域间安全认证根据用户服务双方信息来源进行信任计算,实现对自身信任的初始化处理,将用户直接信息与间接信息进行结合,根据结合结果完成域间用户身份数据转发安全认证算法的构建;对于域内认证,通过虚拟组织进行安全认证,并按照用户身份数据转发安全要求选择相应的认证方式。在域间认证采用身份的PKI技术,通过身份的密钥交换协议设计了一种安全认证算法。实验结果表明,所提算法进行安全认证下用户身份数据相关性强,错误认证情况最少;通过所提算法构建的算法有很高的安全认证可靠性,鲁棒性较高。In traditional authentication algorithms,it is easy to isolate attribute security data as dangerous data,affecting the data processing efficiency.Therefore,a user identity data forwarding authentication algorithm based on PKI technology was proposed.Based on the information sources of the two parties of user service,the inter-domain security authentication performed the trust calculation and completed the initialization of its own trust.User's direct in⁃formation was combined with indirect information.On this basis,the construction of inter-domain user identity data forwarding security authentication algorithm was completed.The intra-domain authentication was achieved by virtual organization,and some appropriate authentication methods were selected according to the user identity data forwarding security requirements.The inter-domain authentication was based on PKI technology.Finally,a secure authentication algorithm was designed through the key exchange protocol.Simulation results prove that the proposed algorithm has strong correlation of user identity data under security authentication.Meanwhile,this algorithm has the least error au⁃thentication.The proposed algorithm has high reliability of security authentication and high robustness.
