Design of Digital Reputation Scoring Model Based on Zero Trust in Edge Computing Environment
Edge computing combines real-time processing near the data source with cloud computing to provide high-efficiency and low-latency computing solutions and build a comprehensive distributed computing system.However,the dis-tributed and internal trust characteristics of edge computing also lead to the problem of fuzzy boundary security.The appear-ance of zero-trust architecture breaks the original static boundary defense mode and makes the device realize dynamic secur-ity in the network.The distributed nature of edge devices however leads to the difficulties of dynamic management in zero-trust architecture,such as complexity and resource limitation.To solve this problem,in this article we propose a digital repu-tation scoring model(DRSM)based on zero trust,which combines with blockchain to realize dynamic access management and authorization in edge computing environment.This scheme is helpful to solve the problem of fuzzy boundary security and reduce the impact of malicious attacks on the system.The simulation results showed that the proposed model could effect-ively reduce the access of abnormal edge devices and improve the security of the system.
