Abstract: A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is to communicate with an NVM. The processor is to store in the NVM at least a Type-Length-Value (TLV) record including one or more encrypted fields and one or more non-encrypted fields, the non-encrypted fields including at least a validity indicator of the TLV record, to read the TLV record from the NVM, and to invalidate the TLV record by modifying the validity indicator stored in the non-encrypted fields, without decryption of any of the encrypted fields.

Abstract: In one embodiment, a device includes a memory to store a first public key indicating security ownership of the device by a first owner, an interface to receive a signature of an intermediate public key signed by a first owner signing service with a first private key, and processing circuitry to load the intermediate public key in the memory, responsively to authenticating the signature, and remove the first public key from the memory, and wherein the interface is to receive a second public key and a signature of the second public key signed by a second owner signing service with an intermediate private key, the processing circuitry is to load a second public key in the memory indicating ownership has been transferred to the second owner responsively to authenticating the signature of the second public key with the intermediate public key, and remove the intermediate public key from the memory.
