Abstract: A communication method and a communications apparatus in which the method includes: a terminal device receiving a first authentication request from a security function network element, and obtaining authentication reference information based on the first authentication request, where the authentication reference information is a response value, a resynchronization token, or a cause indication value. The terminal device sends an authentication response message to the security function network element, where the authentication response message includes a first information element used to carry the response value, a second information element used to carry the resynchronization token, and a third information element used to carry the cause indication value, and the authentication reference information is carried in an information element corresponding to the authentication reference information.

Abstract: A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message. This application is applicable to a process of performing security protection on a NAS message.

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.
