Abstract
An instruction to disable a first cryptographic key of a computing device is received by a processor of the device. The first cryptographic key is embedded in the device during manufacturing to facilitate a boot sequence of the device. The instruction is signed using a cryptographic signature. The first cryptographic key is associated with a first priority indicator. The cryptographic signature is verified using a second cryptographic key embedded in the device during manufacturing. The second cryptographic key is associated with a second priority indicator. The first priority indicator is compared with the second priority indicator. Responsive to determining that the second priority indicator supersedes the first priority indicator, the first cryptographic key is disabled.
