Abstract

The invention provides an identity authentication method, system and device, electronic equipment and a readable medium, and the identity authentication method comprises the steps: receiving a network access authentication request from a terminal, the network access authentication request comprising a user identifier and an encrypted terminal serial number; the encrypted terminal serial number is decrypted, and the decrypted terminal serial number is stored in the local UDM network element; when a serial number synchronization failure message returned by the terminal according to the first network side authentication vector is received, searching the terminal serial number of the terminal locally from the UDM network element according to the user identifier; and generating a second network side authentication vector according to the terminal serial number, and sending the second network side authentication vector to the terminal, so that the terminal authenticates a second network serial number contained in the second network side authentication vector. By encrypting the terminal serial number, the security of information transmission in the authentication process is improved, the terminal serial number is stored in the local UDM network element, and the security of information transmission in the authentication process and the efficiency of the re-authentication process are improved.

Description

technical field [0001] The present disclosure relates to the technical field of network security, and in particular to an identity authentication method, system, device, electronic equipment and readable medium. Background technique [0002] AKA (authentication and key agreement) uses the challenge response mechanism to complete the identity authentication between the terminal and the network, and negotiates the communication encryption key based on the identity authentication. [0003] In the prior art, in the two-way authentication process between the terminal and the network, the network sends an authentication request response to the terminal, including the authentication quintuple vector (RAND, AUTN, XRES, CK, IK), and the terminal will verify the AUTN, including the network side Verification of message authentication code MAC and network serial number SQN. If the SQN is not within the correct range, the terminal will report to the network that the reason for authentic...
