Abstract:
A method and apparatus for authenticated recoverable key distribution are described. In one embodiment, an application key is provided to an integrated chip platform. In one embodiment, the integrated chip platform encrypts the application key with a Key Encryption Key, which is stored within the persistent memory on the platform, and outputs a ChipID and the encrypted application key to enable recovery. In one embodiment, the platform can provide the ChipID to a recovery database to replace a lost encrypted application key. In one embodiment, the ChipID is the public key of a public/private key pair, and the application key is provided to the integrated chip platform by encrypting it using this public key. In one embodiment, the ChipID and the Key Encryption Key are derived from a secret random number programmed into the integrated chip. Other embodiments are described and claimed.
