基于RBAC模型的网络安全访问控制系统

Network Security Access Control System Based on RBAC Model

为缩短网络安全访问控制系统的响应时间,设计了一种基于角色的访问控制(Role-BasedAccess Control,RBAC)模型的网络安全访问控制系统。通过网关设备采用树莓派,外网设备采用路由器完成系统硬件设计。通过设计RBAC模型的知识库、基于RBAC模型的身份认证功能、用户信任值评估功能完成系统软件设计。仿真实验结果表明,当并发用户数量为10 000时,本文设计的网络安全访问控制系统的平均响应时间为1.38 s,工作效率较好,具有一定的应用价值。

In order to reduce the response time of network security access control system,this paper designs a network security access control system based on Role-Based Access Control(RBAC)model.The gateway equipment adopts Raspberry Pi,and the external network equipment adopts routers to complete the system hardware design.The system software is designed by designing the knowledge base of RBAC model,the identity authentication function based on RBAC model,and the user trust value evaluation function.The simulation results show that when the number of concurrent users is 10000,the average response time of the network security access control system designed in this paper is 1.38 s,which is efficient and has certain application value.
