摘　　要：介绍一种基于并行计算的安全认证服务器系统,给出该系统的算法模型。认证服务器的并行环境采用主从模式,私钥分段按照一定顺序存放到各个物理节点中,主节点控制认证流程及私钥发放,从节点保存私钥及密钥计算。在算法模型的基础上实现原型系统,对该方案的安全性能进行了评价。实验结果表明该方案具有抗攻击能力强、认证速度快和结构稳定的特点。This paper proposes a security authentication server system based on parallel computing, and it gives the system＇s algorithm model. The authentication server environment uses the parallel master-slave mode. The privacy segment is saved in the physical nodes in accordance with sub-private key. The master node controls certification process as well as distributing private key from the node. The slave node preserves key and private key calculation. The prototype system is realized based on the algorithm model, and the safety program is evaluated. Results show that the method has a strong anti-attack capability, speed certification and stability of the structure characteristics.
