摘要

PROBLEM TO BE SOLVED: To correct an expectation value to be used for authenticating a main control board by a simple method and to prevent fraudulent control from the main control board to a peripheral board and misappropriation of the expectation value. SOLUTION: In the electronic device provided with the main control board 310 and the peripheral board 330 for performing prescribed processing on the basis of a control command transmitted by the main control board 310, the main control board 310 adds correction data of the expectation value to be used for collation of data transmitted from the main control board 310, authentication data for authenticating the main control board 310 or dummy data of the authentication data when the control command to be transmitted to the peripheral board 330 is a command for controlling demonstration display to be displayed during the standby of main processing. The peripheral board 330 authenticates the main control board 310 as it is when receiving the dummy data, and authenticates the main control board 310 using the corrected expectation value when receiving the authentication data.
