摘　　要：提出了一种基于格的多信任域认证协议模型。该模型以格的特有属性来支持不同信任域间的双项实体认证及大规模跨域的联合认证。避免了由某个独立的特权机构认证所带来的安全隐患以及网络瓶颈和单点崩溃问题。解决了基于代理跨域认证的庞大通信规模和因缺乏灵活性而不适应现代网络环境的问题。经仿真实验和性能分析表明,该模型具有很高的安全性,且在大规模跨域的联合认证时更灵活、轻量及高效。A lattice-based authentication protocol model for multi-domain was proposed. The model supports mutual entity between different trust domains and unites authentication of large-scale cross-domain, which avoids the potential security hazard, network botdeneek and single-point collapse problems by certain independent prerogative organization authentication in the traditional method. Gigantic communications scale based on vicegerent cross-domain authentication and unadapted modem network environmental problem owing to lack of flexibility were simultaneously solved. The model has higher security by emulation experiment and performance analysis, and it is more flexible, lightweight and efficient in the united authentication of large-scale cross-domain.
