1. A system for authenticating a first device attached to a second device, the system comprising;
- a first ID generator, arranged in the first device, for generating a first identification signal;
a second ID generator, arranged in the second device, for generating a second identification signal; and
an authentication device, arranged in the second device and connected to the first and second ID generators, for receiving the first and second identification signals from the first and second ID generators, comparing the first and second identification signals, and authenticating the first device based on the comparison result.

Abstract
A system for authenticating an external device attached to a main device. The system includes a first ID generator, arranged in the external device, for generating a first identification signal. A second ID generator, arranged in the main device, for generating a second identification signal. An authentication device compares the first and second identification signals and authenticates the external device based on the comparison result. The second ID generator is configured by a semiconductor device. Thus, the system has a high level of security with respect to the confidentiality of encryption information.

12. An ID generator for incorporation in a main device to which an external device is attached, the main device including an authentication device for authenticating the external device based on a first identification signal of the external device and a second identification signal of the main device, the ID generator comprising:
-
a communicator for performing a communication process with the authentication device; and
a encryption processor for performing a predetermined encryption process on a code to generate the second identification signal and providing the second identification signal to the authentication device via the communicator, the communicator and the encryption processor each being configured by a semiconductor device. - View Dependent Claims (13, 14, 15)
