Abstract: This application provides a communication method and apparatus. The method includes: A first network element receives a first request message from a second network element, where the first request message is used to request to perform a first operation on a first terminal device. The first network element determines, based on the first request message, whether the second network element is authorized to request to perform the first operation on the first terminal device. Whether a network element that sends a request message is authorized to request to perform a related operation is verified, to determine whether the network element is an attacker. This reduces impact on a system service resulting from requests of an attacker and improves system security.

Abstract: A discovery method and apparatus based on a service-based architecture, where the method includes a control network element sending a discovery response to a first functional network element, where the discovery response includes a determined security parameter and an access address or an identifier of a second functional network element. The first functional network element receives the discovery response from the control network element, and sends an access request to the second functional network element based on the address or the identifier of the second functional network element, where the access request includes the received security parameter. The second functional network element receives the access request from the first functional network element, verifies correctness of the security parameter, and determines, based on the correctness of the security parameter, whether the access request is authorized by the first functional network element.

Abstract: An authentication management function AUSF receives an authentication request message from an access and mobility management function AMF, where the authentication request message carries a subscription concealed identifier SUCI. The AUSF sends an authentication vector get request message to a unified data management UDM function, where the authentication vector get request message carries the SUCI. The AUSF receives an authentication vector get response message from the UDM, where the authentication vector get response message includes authentication and key management for application AKMA indication information. The AUSF generates, based on the AKMA indication information, an authentication and key management for application-key identifier based on a routing indicator RID in the SUCI.

Abstract: This application provides a communication method and apparatus. The method includes: a terminal sending first network information of a second network to a first network, where the first network information includes first indication information of the second network, and the first indication information indicating that the terminal requests to access the second network. The terminal performs onboarding delivery authentication of the second network through the first network. After onboarding delivery authentication of the second network succeeds, the terminal receives configuration information of the first network through the first network, and obtains a credential of the second network through the first network from an online sign-up server in the second network.

Abstract: This application provides a method for protecting a truncated parameter and an apparatus, and relates to the field of communications technologies, to ensure security of a truncated parameter in a transmission process. The method includes the following steps: A mobility management network element determines whether a terminal that accesses a network meets a preset condition, where the preset condition includes that the terminal uses a control plane CIoT 5GS optimization function. The mobility management network element sends, to the terminal when the terminal meets the preset condition, a downlink NAS message on which NAS security protection is performed by using a NAS security context, where the downlink NAS message includes a truncated parameter. This application is applicable to a truncated parameter transmission process.
