Abstract: This application provides a user authentication method and an apparatus. Before establishing, for a terminal device, a session used to transmit service data, an SMF entity receives a session establishment request message; determines, based on the session establishment request message, to perform user authentication on a user using the terminal device; and sends a session establishment message to a UPF entity, where the session establishment message is used to establish a first session for the terminal device, and a session attribute of the first session is: a session used to transmit only a user authentication message. Subsequently, the terminal device and an AAA server transmit the user authentication message through the first session, to complete user authentication.

Abstract: A service application programming interface (API) invoking method where a security method applied to an API exposing function entity is updated from an original security method to a new security method, and where the security method of the API exposing function entity is used for communication between the API exposing function entity and an invoker. The method includes: obtaining, by the invoker, a new security method of the API exposing function entity; and sending, by the invoker, a first invoking request to the API exposing function entity using the new security method, where the first invoking request includes a name of a service API, and where the first invoking request is used to invoke the service API.

Abstract: The present disclosure provides example terminal devices, road side units, and servers. One example terminal device performs operations including sending certificate request information to a certificate authority server, where the certificate request information includes identity information of the terminal device. A communication key sent by the certificate authority server is received by the terminal device. Encrypted information that is sent by a road side unit is received by the terminal device, where the encrypted information is information encrypted by using the communication key. The encrypted broadcast information is decrypted by the terminal device by using the communication key.

Abstract: In a method for security handling in a mobility of a terminal device, a target access and mobility management function (AMF) entity receives a first message for registering a terminal device, sends a second message to a source AMF entity after receiving the first message. The source AMF entity derives a first key based on a key between the source AMF entity and the terminal device, sends the first key to the target AMF entity. The target AMF entity determines to use the first key based on security related information after receiving the first key and determines a communication key between the target AMF entity and the terminal device based on the first key after determining to use the first key.

Abstract: In a communication method, when MAC addresses in a plurality of VSI messages conflict, in response to only some of the VSI messages, a VSI message receiving end sends an action response message carrying a conflicting MAC address. In this way, a device that can correctly decrypt the action response message can decrypt, for a few times, ciphertext information in received action-request messages using a key of the device.

Abstract: This application provides a method for restricting access of a terminal device, and an apparatus. The method includes: receiving, by an access network device, a first identifier that is from a terminal device, where the first identifier is used to identify the terminal device; and if the first identifier matches a second identifier, restricting, by the access network device, access of the terminal device, where the second identifier is used to identify a terminal device having abnormal behavior. Based on the solution, the access network device pre-records the second identifier of the terminal device having the abnormal behavior.
