ABSTRACT:
To realize device authentication which is highly resistant to attacks with simple procedures. Hence, an authentication unit of an image input apparatus transmits first data to an authentication unit of an information holding device, and receives, from the authentication unit, encrypted key information and second data which is generated from the first data. The authentication unit authenticates a partner device based on the first data and second data. In the case that authentication is successful, the authentication unit of the image input apparatus decrypts the encrypted key information to acquire key information. Then the image input apparatus encrypts data using the key information, and transmits the encrypted data to the partner device.
