  • Publication number: 20210320788
    Abstract: Example communication methods and apparatus are described. One example communication method includes that user equipment (UE) sends an N1 message to a security anchor function (SEAF), where the N1 message carries a Diffie-Hellman (DH) public parameter or a DH public parameter index, the N1 message further carries an encrypted identifier of the UE, and the encrypted identifier is obtained by encrypting a permanent identifier of the UE and a first DH public key. The UE receives an authentication request that carries a random number and that is sent by the SEAF. The UE sends, to the SEAF, an authentication response used to respond to the authentication request, where the authentication response carries an authentication result calculated based on a root key and the random number.
