摘　　要：提出了一种基于超立方体的跨域认证协议模型.该模型利用超立方体的结构特征,支持不同信任域间的实体双向认证.相对于传统跨域认证模型,减少了认证服务器间注册的工作量,简化了认证服务器间共享密钥的分配和管理工作.该模型还能够避免由单一权威机构认证所带来的网络瓶颈和单点崩溃等问题.分析表明,该协议模型具有较高的安全性和可靠性,从而使应用服务器能够有效地进行访问控制,保障网络安全.A new cross-domain authentication protocol model is developed on hypercube basis, where the structural features of hypercube support the reversible entity authentication between different trust domains. Compared with the conventional cross-domain authentication model, the proposed model is able to not only reduce the registration workload but also simplify the distribution and management of shared cipher keys among authentication servers. In addition, the model can avoid the network bottleneck and single-point collapse due to the authentication by a single authority. Analytical results showed that the protocol model is highly secure and reliable, thus enabling the server in application to access and control so as to ensure the network security.
