基于IPv6环境的网络信息安全访问控制模型设计

Design of Network Information Security Access Control Model Based on IPv6

传统的访问控制模型因未对网络信息进行预处理,增大了控制结果的偏差以及控制延时,降低了网络信息的利用率。对此,基于IPv6环境设计了新的网络信息安全访问控制模型,采用ReliefF算法选取网络信息最优特征子集,经PCA降维后,结合ICA过程对降维后的信息进行预处理,引入信任值以及上下文约束概念,构建访问控制模型,通过模型实现访问控制。实验结果表明:该模型不仅能够降低网络信息安全访问控制偏差和延时,同时还能够增强网络信息的利用率,具有良好的应用效果。

Traditional access control model does not preprocess network information,which increases the deviation of control results and control delay,and reduces the utilization of network information.Therefore,this study designs a new network information security access control model based on IPv6.ReliefF algorithm was used to select the optimal feature subset of network information.After PCA dimensionality reduction,it was preprocessed with ICA process.The concept of trust value and context constraint was introduced to construct an access control model,and access control was realized by the model.Experimental results show that this model can not only reduce the deviation and delay of network information security access control,but also enhance the utilization of network information,and it has good application effect.
