Abstract

The invention discloses a user terminal network authentication method and device, which are used for solving the problems that equipment operation and maintenance cost is high and that the authentication efficiency and the authentication safety are not high in an authentication process of the user terminal access network. The method comprises the steps as follows: a first terminal encrypts identity information of the first terminal based on a physical layer sharing secret key generated through a channel characteristic parameter between the local and a base station and sends the encrypted identity information to a network server; a user authentication vector generated by the network server based on the identity information is received; network authentication is completed based on the user authentication vector; and the network server is triggered to notify other user terminals of the same group as the first terminal to perform network authentication by adopting the user authentication vector. By the adoption of the method, the terminal can encrypt the identity information of the terminal based on the physical layer sharing secret key generated through the channel characteristic parameter between the local and the base station and transmit the identity information; thus, the probability of terminal identity information leakage is reduced.

Description

technical field [0001] The invention relates to the field of communication security, in particular to a network authentication method and device for group terminals. Background technique [0002] With the development of communication technology, Machine Type Communication (MTC) is an important application scenario in Long Term Evolution (LTE) and future fifth-generation mobile communication technology (5-Generation, 5G) networks . According to the existing 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) standard, when a large number of group devices are connected to the network at the same time, the network needs to perform an authentication for each group device separately, which may cause network congestion At present, the method of 3GPP network group authentication based on the master device (Group Leader) is usually used to solve the above-mentioned problem of network congestion. [0003] During the group establishment process, the operato...
