Authentication method for 5G technology

Abstract

The invention provides an authentication method for a 5G technology, and the method comprises the steps that a base station judges whether there is wireless channel response information correspondingto a user link of a user terminal at a previous moment or not when the user terminal communicates with a network; if yes, the base station extracts channel response information from the physical layerpilot frequency and compares the channel response information with the wireless channel response information of the user link at the previous moment, and if the difference value between the channel response information and the wireless channel response information of the user link at the previous moment is smaller than a preset threshold value, the base station passes the authentication of the user terminal and allows the user terminal to access; and if not, the base station sends information used for prompting that identity authentication needs to be carried out to the user terminal. The base station verifies the user terminal in two different modes according to whether the wireless channel response information corresponding to the user link of the user terminal at the previous moment exists or not, is simple and convenient, and can meet the requirement for network access security in a 5G network.

Description

technical field [0001] The invention relates to the technical field of wireless communication security, in particular to an authentication method for 5G technology. Background technique [0002] 5G provides users with a better user experience with faster speed, larger capacity, and lower cost. At the same time, it also brings more security challenges and faces more extensive security threats. Mass user access and multi-level heterogeneous converged networks bring higher security requirements to 5G network access. [0003] The inherent openness and broadcasting characteristics of the wireless network itself determine that it is more vulnerable to various attack methods such as eavesdropping, interception, and interference than traditional computer networks, and the devices in the wireless network are also more likely to be tampered with. These inherent problems of wireless networks greatly undermine the integrity, confidentiality, reliability and availability of communicatio...
