摘要： A program storage unit 111 stores a plurality of protected programs. The disabled-program list storage unit 117 stores information of disabled protected programs. An execution program selection unit 112 selects one of the protected programs that is not disabled, with reference a disabled-program list. If malicious analysis is detected before the protected program is executed or during the execution of the protected program, a malicious analysis detection unit 116 stops the execution of the protected program, and a disabled-program update unit 118 enters the disabled program into the disabled-program list.

摘要： An authentication system verifies an authentic computer program, certifies the authenticity itself, and verifies a certification. The authentication system includes a terminal (e.g., requesting device) and a card (e.g., verifying device). The card stores secret information to be used by the terminal, and an update program for the terminal. The card verifies authenticity of the terminal using information obtained from the terminal. When it judges that the terminal is authentic, the card outputs the secret information to the terminal. When it judges that the terminal is not authentic, the card outputs the update program. The terminal is forced to update the program when it attempts to use the secret information.

摘要： An authentication system that can show having an authentic computer program, can certify the authenticity of itself, and can verify the certification. The authentication system is composed of a terminal (requesting device) and a card (verifying device). The card stores secret information to be used by the terminal, and an update program for the terminal. The card verifies authenticity of the terminal using information obtained from the terminal. When it judges that the terminal is authentic, the card outputs the secret information to the terminal. When it judges that the terminal is not authentic, the card outputs the update program. With this structure, the terminal is forced to update the program when it attempts to use the secret information.

摘要： A data storage apparatus is provided that realizes a measure against deterioration of a flash memory in which integrity check data is stored. A content playback apparatus (1000) uses a hash value of playback history information as integrity check data (confirmation data) for confirming whether the playback history information has been falsified. A first address calculation unit (1004) and a second address calculation unit (1006) determine a read-in address and a storage destination address for the integrity check data, with use of the hash value. Accordingly, the storage destination addresses can be diffused, thus enabling preventing deterioration of the flash memory.
