<P>PROBLEM TO BE SOLVED: To prevent malfunction of a peripheral device in case of camouflage of a central processing unit, an unauthorized change of a state of an input-output port of a SAM, and so on. <P>SOLUTION: An authentication processing device executes authentication processing according to a command for authentication from a central control device and outputs an authentication result to the central control device, and includes a storage means for storing a key identifier and an encryption key data in association with each other. When the command for authentication including an authentication data and identification information of the command for authentication is inputted through an input-output port for authentication processing, the authentication processing device specifies the key identifier based on the identification information, acquires the encryption key data corresponding to the specified key identifier from the storage means, executes authentication processing by using the acquired encryption key data and the authentication data, and outputs an operation signal to operate a peripheral device through an input-output port for peripheral device related to the authentication processing when the authentication processing is successful. <P>COPYRIGHT: (C)2012,JPO&INPIT |
