ABSTRACT:
A secure removable card has electrical connections for communication therewith. The card comprises a first integrated circuit die, with the first die including a processor. The card has a second integrated circuit die, with the second die including a non-volatile memory for storing a secret key, and a controller for controlling the operation of the non-volatile memory. A bus connects the first die with the second die. The processor can generate a key pair, having a public key portion and a private key portion upon power up, and transfers the public key portion across the bus to the second die. The controller can receive the public key and encrypt the secret key with the public key to generate a first encrypted key, and can transfer the first encrypted key across the bus to the first die. The processor can receive the first encrypted key and can decrypt the first encrypted key to recover the secret key, and can encrypt data with the secret key for communicating along the electrical connections external to the card.
