Abstract
Described are a hardware encryption engine, and secret key registration and authentication system recoverable binary bit using knowing an initial secret key stored in the master system. The secret key is overwritten in each authentication, updating it to the master and encryption engine independently. The secret key over write command can be preferably given to the chip as a CHG, and the non recoverable binary bit from the sense amplifier is used for response.
