Terminal equipment access authentication method and system based on edge computing

Abstract

The invention discloses a terminal equipment access authentication method and system based on edge computing. The method comprises the following steps: S1, key sharing, sharing a key between the terminal equipment and the edge computing server; S2, system initialization authentication: accomplishing mutual initial identity authentication between the terminal equipment and the edge computing serveraccording to the key and the lightweight cryptography algorithm; S3, physical layer channel authentication modeling: verifying the data legality from the fourth-frame data by the edge computing server; S5, upper cryptography authentication: starting the upper cryptography authentication if the legality of the received data frame cannot pass the model authentication at the non-initialization authentication stage; and S6, physical layer channel authentication model updating: updating the physical layer channel authentication model when j data frames continuously received by the edge computing server in the coherent time need to start the upper cryptography authentication. Through the method disclosed by the invention, the complexity of the terminal equipment identity authentication is reduced, and the security and the authentication rate of the identity authentication are improved.

Description

technical field [0001] The present invention relates to terminal equipment access authentication, in particular to an edge computing-based terminal equipment access authentication method and system. Background technique [0002] With the rapid development of Internet of Things technology, various terminal devices (nodes) will be widely used in daily life and work. Due to the inherent limitations of traditional cloud computing systems, such as inability to meet real-time control, heavy network traffic load, cloud data privacy security cannot be guaranteed, and so on. The emerging edge computing technology can just provide edge intelligent services for IoT devices, build small edge data centers, and micro-cloud data centers, which can meet the needs of related industries in digital fast connection, real-time business, data optimization, application intelligence, and data security. Key requirements in terms of privacy protection and so on. Edge computing nodes (servers) have ...

AI Technical Summary

Problems solved by technology

Due to the limited computing and storage capabilities and energy consumption of communication terminal equipment, it is not suitable to directly use traditional complex encryption algorithms to achieve identity authentication. Therefore, it is necessary to design an identity authentication that is suitable for this edge computing communication system with asymmetric resources. Program
