Abstract
Systems and methods are disclosed to generate a persistent identifier for a device using a trusted platform module (TPM) of the device, so that the identifier is persistent during the lifetime of the TPM. In embodiments, during an initialization of the TPM, the system obtains an entropy value from the TPM used to generate the device's persistent identifier. The identifier is written to a non-volatile storage of the TPM so that it cannot be erased during the lifetime of the TPM. In embodiments, a persistent keys pair is generated based on the identifier, and also permanently written to the non-volatile storage. In embodiments, the persistent identifier may be measured and verified via TPM quotes. In embodiments, the persistent private key may be used to sign a nonce to prove the identity of the device.
