Original Abstract Submitted

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.
