KEY TERMINAL APPARATUS, LSI FOR ENCRYPTION PROCESS, UNIQUE KEY PRODUCING METHOD, AND CONTENT SYSTEM |
摘要 |
A key terminal apparatus includes a crypto-processing LSI that performs predetermined crypto-processing. Unique information identifying the crypto-processing LSI is embedded in the crypto-processing LSI. A predetermined master key corresponding to a predetermined key is embedded in the crypto-processing LSI. The crypto-processing LSI (a) receives an encrypted manufacturer key from the manufacturer key storage unit, (b) decrypts the encrypted manufacturer key using the predetermined master key to generate a manufacturer key, (c) generates a unique manufacturer key identical to the predetermined unique manufacturer key, based on the unique information embedded in the crypto-processing LSI and the generated manufacturer key, and (d) decrypts the received encrypted device key using the generated identical unique manufacturer key to generate a predetermined device key.
