Abstract
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.
