Abstract: The technology of this application relates to the communication field, and provides an authentication method, an information sending method, a processing method, and a communication apparatus, to resolve a problem that authentication reliability is low because an authentication procedure can be triggered by only a mobility management function, and improve the authentication reliability. The method includes a first network function determining first information, where the first network function belongs to a home network of user equipment. The first network function selects a first mobility management function based on the first information, where the first mobility management function belongs to a first serving network with which the user equipment is registered, and, the first network function sends a first request to the first mobility management function, where the first request requests the first mobility management function to perform a first authentication procedure on the user equipment.

Abstract: A signaling protection method, apparatus, and system prevents an NF from spoofing an NF of another PLMN under a shared SEPP to access a peer PLMN service, so that system security is improved. A first SEPP serving a first PLMN receives a third service request that is from an NF of the first PLMN and that is sent to an NF of a second PLMN. A second SEPP serves the second PLMN, and a connection that is between the first SEPP and the second SEPP and is for the first PLMN and the second PLMN includes first N32-f. The first SEPP determines a first PLMN identifier based on configuration information. The first SEPP determines a first N32-f context context identifier corresponding to the first PLMN identifier, where the first N32-f context identifier corresponds to the first N32-f.

Abstract: Embodiments of this application provide a connection resume method and an apparatus. The method includes: A terminal device sends a first message that carries first indication information to a first network device. The first indication information is used to indicate to calculate a resume MAC value based on a first parameter set. The first parameter set includes one or more of a resume cause value or an RRC resume request message. The terminal device receives a second message from the first network device. When the second message carries second indication information, the terminal device sends an RRC resume request message that carries the resume MAC value to a second network device. The second indication information is used to indicate to verify the resume MAC value based on the first parameter set.
