Method and apparatus for authenticating terminal, computer device and storage medium

An apparatus for authenticating a terminal, comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• receiver code configured to cause the at least one processor to receive an authentication request of a request terminal, the authentication request including a first media access control address and a first message integrity code of the request terminal;
• acquisition code configured to cause the at least one processor to determine a target key-value pair from a plurality of key-value pairs based on the first media access control address, and determine at least one first preshared key corresponding to the first media access control address from the target key-value pair, any of the plurality of key-value pairs comprising a media access control address of a terminal and at least one historical preshared key which has been connected by the terminal, and the media access control address of the terminal in any of the plurality of key-value pairs being a historical successfully-authenticated address;
• generation code configured to cause the at least one processor to generate at least one second message integrity code corresponding to each of the at least one first preshared key, one first preshared key corresponding to one second message integrity code;
• and
• authentication code configured to cause the at least one processor to authenticate the request terminal based on the first message integrity code and the at least one second message integrity codes.
