An Authentication Method Applicable to LEO Satellite Internet of Things

Abstract

The present invention discloses an authentication method suitable for low-orbit satellite Internet of Things, including the following steps: S1, classify user groups, and group terminal devices according to the classification results; S2, start and register terminal devices, each The terminal devices all communicate with the HSS group key and personal private key; S3, the satellite sends an authorization management signal to each group of terminal devices and provides services to the authorized terminal devices; S4, each group of terminal devices communicates through the received authorization management signal Self-authentication; S5, the terminal device sends the identity information of the device to the satellite for verification; S6, the satellite verifies the user group to which the terminal device belongs, and sends the identity information of the device and the data information sent by the device to the gateway station; S7, The data processing gateway verifies the terminal equipment, and if it succeeds, it sends the data to the core network, and if it fails, it discards the data. The method of the invention has strong pertinence and adaptability, and has excellent application effect.

Description

technical field [0001] The invention relates to an authentication method, in particular to an authentication method suitable for low-orbit satellite Internet of Things, belonging to the technical field of Internet of Things. Background technique [0002] With the development of IoT technology, more and more IoT devices need to be connected to the core network to meet various application requirements of users. Today, there are more than 16 billion connected devices in the world. According to Ericsson's forecast, by 2021, the number of global device connections will exceed 30 billion. In the application scenario of low-orbit satellite Internet of Things, for some remote areas, especially some areas where the environment is harsh and the base station signal cannot be covered, satellites, as the only support point for remote connections, will face the pressure of large data volume terminal connections. And this pressure is even greater than that of ground equipment. The reason...

AI Technical Summary

Problems solved by technology

In the face of multiple constraints such as massive device connections, shortage of on-board resources, and excessive computing and bandwidth overhead, in order to solve the problems of difficult authentication and high failure rate of massive terminals in the low-orbit satellite environment, it is necessary to propose a new applicable Authentication method in LEO satellite IoT environment
