Abstract: A trusted attestation method and a communication apparatus are provided. The method includes: A first node obtains information about a first blockchain, and the first node determines attestation information based on the information about the first blockchain. The attestation information is used to remotely attest whether the first node is trusted. The information about the first blockchain may be used as a common random number that is generated by the first blockchain based on a consensus and that can be used by a plurality of nodes. Therefore, the information about the first blockchain may be used as a challenge value for performing security measurement by the plurality of nodes. The attestation information may be verified by any verifier to implement measurement for one time and verification for a plurality of times, so that the first node does not need to establish a separate “challenge-response” procedure with each verifier.

Abstract: A communication method integrated with trustworthiness measurement, including: a first network element sends a first data packet, where the first data packet includes first request information, and the first request information is used to request to verify whether a second network element is trusted. The first network element receives a second data packet, where the second data packet includes first response information, and the first response information is used to verify whether the second network element is trusted.

Abstract: A method includes: a network function service consumer sends a service request message, where the service request message is used to request to obtain a service provided by a network function service provider. The network function service consumer receives a service response message, where the service response message indicates whether the service request message is accepted, and further indicates a result of trustworthiness verification of the network function service consumer. The method helps the network function service provider verify, before providing the network service, an identity of the network function service consumer and determine whether the network function service consumer is trusted, to help improve security of communication between core network elements and improve security of a core network device.
