US Patent 11477036 Devices and methods for application attestation

A device receives, from an application, a request to access an attestation key stored in a secure element of the device. The device obtains an attestation policy, by which to verify an identity of the application. The device examines an application file associated with the application, to determine whether the application file satisfies the attestation policy. The device selectively generates a temporary key based on a result of examining the application file. The temporary key may be used to access the attestation key. The temporary key may be generated based on the application file satisfying the attestation policy, and may not be generated based on the application file not satisfying the attestation policy.
