Abstract (en)
[origin: WO2021063484A1] Devices and methods for attestation are disclosed. A device for attestation, comprising: a computing circuitry having a processor being configured to: acquire a sealing key from the processor, decrypt a private key from an encrypted private key based on the sealing key, and sign a report from a challenger based on the private key. This solution does not need to use the key stored in the processor for the signing of the report, and enables any entity to provide an alternative attestation service which can be used by organizations that trust the entity, and flexibility of the attestation service is thus improved.
