Title: Authenticated device, authentication system, and authentication method
Inventor: HORI KENJIRO
IPC: B41J29/00
Filed: 2020-03-05
Abstract: To make duplication of an authenticated device more difficult than before.SOLUTION: An authenticated device receives identification information, a password, and a challenge from an authentication device, and performs password authentication. When the password authentication is performed successfully, the authenticated device acquires an encrypted authentication operation code which is a program code stored corresponding to the identification information. The authenticated device decrypts the executable authentication operation code from the encrypted authentication operation code by using the password for which the password authentication is performed successfully. The authenticated device applies the challenge to the authentication operation code and executes the authentication operation code to generate a response.SELECTED DRAWING: Figure 3
