A terminal trusted access and dynamic evaluation system for ultra large scale internet of things

Abstract

The invention discloses a terminal trusted access and dynamic evaluation system for ultra large scale Internet of things, which relates to the field of Internet of things security technology.The system aims to solve the technical problems of strong heterogeneity of terminals, low efficiency of access authentication, and lag of trusted state evaluation in the super large scale Internet of things scenario.The system includes four core parts: terminal trusted collection layer, hierarchical authentication gateway cluster, cloud trusted evaluation platform and dynamic adaptation scheduling module.The invention realizes the efficiency of ultra large scale IOT terminal access, the real-time performance of trusted evaluation and the accuracy of response, significantly improves the overall security protection ability of IOT system, and can be widely used in smart cities, industrial Internet and other ultra large scale IOT scenarios.
