Abstract
An integrated circuit includes a secure hardware environment having a first input that receives a key number. A key generation device generates a secret key from the key number and a unique key. A signature generation device generates a signature associated with the key number. A second input of the secure hardware environment receives encrypted binary data. A decryption device operates to decrypt the received encrypted binary data using the secret key. A third input the secure hardware environment receives an authentication signature. An authentication device authorizes use of the secret key to decrypt only if the signature generated by the signature generation device is identical to the authentication signature.
