ABSTRACT:
A peripheral device that is connected to a main body as an authentication requesting device operates as a device to be authenticated. Receiving code-related information from the main body, the peripheral device acquires a challenge code on the basis of the received code-related information, generates encrypted information by encrypting the challenge code, and transmits encryption-related information that relates to the generated encrypted information to the main body. The code-related information is part of the challenge code and/or the encryption-related information is part of the encrypted information.
