An integrity measurement method, wherein the method comprises: performing, by a first measurement module, integrity measurement on a second measurement module to obtain a first measurement result, wherein credibility of the first measurement module is higher than credibility of the second measurement module; receiving, by the first measurement module, a second measurement result sent by the second measurement module, wherein the second measurement result is obtained by the second measurement module performing integrity measurement on a to-be-measured object; and sending, by the first measurement module, measurement result information to an attestation module, wherein the measurement result information is determined based on the first measurement result and the second measurement result, and the attestation module is configured to determine, based on the measurement result information, whether the to-be-measured object passes integrity verification, wherein the method further comprises: receiving, by the attestation module, the measurement result information, characterized in that the measurement result information comprises the first measurement result and the second measurement result; and if the attestation module determines that the first measurement result is the same as a first baseline value corresponding to the second measurement module, and the second measurement result is the same as a second baseline value corresponding to the to-be-measured object, determining that the to-be-measured object passes integrity verification; and if the attestation module determines that the first measurement result is different from a first baseline value, or determines that the second measurement result is different from a second baseline value, determining that the to-be-measured object fails integrity verification. performing, by a first measurement module, integrity measurement on a second measurement module to obtain a first measurement result, wherein credibility of the first measurement module is higher than credibility of the second measurement module; receiving, by the first measurement module, a second measurement result sent by the second measurement module, wherein the second measurement result is obtained by the second measurement module performing integrity measurement on a to-be-measured object; and sending, by the first measurement module, measurement result information to an attestation module, wherein the measurement result information is determined based on the first measurement result and the second measurement result, and the attestation module is configured to determine, based on the measurement result information, whether the to-be-measured object passes integrity verification, wherein the method further comprises: receiving, by the attestation module, the measurement result information, characterized in that the measurement result information comprises the first measurement result and the second measurement result; and if the attestation module determines that the first measurement result is the same as a first baseline value corresponding to the second measurement module, and the second measurement result is the same as a second baseline value corresponding to the to-be-measured object, determining that the to-be-measured object passes integrity verification; and if the attestation module determines that the first measurement result is different from a first baseline value, or determines that the second measurement result is different from a second baseline value, determining that the to-be-measured object fails integrity verification. receiving, by the attestation module, the measurement result information, characterized in that the measurement result information comprises the first measurement result and the second measurement result; and if the attestation module determines that the first measurement result is the same as a first baseline value corresponding to the second measurement module, and the second measurement result is the same as a second baseline value corresponding to the to-be-measured object, determining that the to-be-measured object passes integrity verification; and if the attestation module determines that the first measurement result is different from a first baseline value, or determines that the second measurement result is different from a second baseline value, determining that the to-be-measured object fails integrity verification.
