Abstract

See full text

Various embodiments provide a method and an apparatus for determining a trust status of a TPM, and a storage medium, and pertains to the field of data security technologies. In those embodiments, a verifier send an unsealing request to a host, so that the host unseals current PCR values in the TPM based on a seal key handle carried in the unsealing request, and sends verification information to the verifier based on the unseal verification key obtained after the unsealing. Therefore, any verifier that establishes an encrypted channel with the host can determine the trust status of the TPM in the host based on a second verification key transmitted on the encrypted channel, and there is no need to pre-deploy a remote attestation server to determine the trust status of the TPM.
