Abstract
A computing device is configured with a hardware root of trust ('HRoT'). The HRoT and a remote registration server exchange public keys while the device is in a trusted environment. The device is then locked by setting a lock status in the HRoT. The device can then be shipped to a recipient. When the device is powered on following transit, the HRoT pauses booting of the device. If a request to unlock the device is received, the HRoT provides an encrypted one-time password to the registration server. The registration server decrypts the one-time password and provides the decrypted one-time password to the HRoT. If the HRoT determines that one-time password received from the registration server is identical to the one-time password it generated, the HRoT sets the lock status of the device to unlocked and allows the device to boot.
