Internet of things terminal secure access method and system based on edge computing

Abstract

The invention discloses an Internet of things terminal secure access method and system based on edge computing. The method comprises the steps that an edge computing device carries out radio frequencyradiation signal collection on each legal sensing device, thereby obtaining collection results; the edge computing device preprocesses each legal device signal, removes outliers and carries out datanormalization on collected signals of each time; the edge computing device generates features through utilization of the normalized data, extracts feature vectors to generate feature data sets and transmits the feature vector sets to a cloud server; and the cloud server selects a classification algorithm to generate a data model, trains the data model according to the feature data sets and transmits an obtained decision-making model to the edge computing device. According to the method and the system, the data processing and access judgment are carried out at the edge computing side, and the method and the system are applicable to an Internet of things device interconnection scheme with limited resources and have the advantages of low computing complexity and high authentication accuracy.

Description

technical field [0001] The invention relates to secure access of wireless terminals, in particular to a method and system for secure access of Internet of Things terminals based on edge computing. Background technique [0002] In the future wireless communication system, the number of smart devices pouring into the wireless network will increase exponentially. Whether it is smart city, smart home, smart logistics, telemedicine, Industry 4.0, smart grid, smart transmission, all will usher in the era of the Internet of Everything. According to CISCO's forecast, by 2020, there will be 26 billion IoT devices connected to the Internet [1]. The access of so many wireless sensors will inevitably bring about a series of security issues, such as secure transmission of massive data collection, secure access authentication, access control management, device data privacy protection, storage security, etc., using traditional cloud computing The cloud system cannot meet real-time contro...
