ABSTRACT:
Keys (e.g., decryption key, authentication key) are stored in a non-volatile memory of a display unit. The keys are retrieved in encrypted form into an integrated circuit. The integrated circuit decrypts the keys and uses the keys. As the keys are available in decrypted form only within the integrated circuit and potentially only during use, the keys may not be available to unauthorized third parties.
