Authentication method, communication apparatus, and computer-readable storage medium

A communication apparatus, comprising:

• a processor, configured to:
• determine whether a terminal needs to be authenticated, obtain an authentication material based on determining that the terminal needs to be authenticated, and obtain a first authentication vector based on the authentication material;
• and
• a transceiver, configured to cooperate with the processor to send a first authentication request message to an access and mobility management network element to trigger authentication on the terminal, wherein the first authentication request message comprises the first authentication vector.

A non-transitory computer-readable storage medium, comprising computer-executable instructions, which upon being run on a computer of a first function network element, the computer is enabled to perform an authentication method including:

• determining, in a home network, whether a terminal needs to be authenticated;
• obtaining, an authentication material based on determining that the terminal needs to be authenticated;
• obtaining, a first authentication vector based on the authentication material;
• and
• sending, a first authentication request message to an access and mobility management network element to trigger authentication on the terminal, wherein the first authentication request message comprises the first authentication vector.
