AUTHENTICATION SYSTEM, METHOD FOR AUTHENTICATION, AUTHENTICATION DEVICE AND DEVICE TO BE AUTHENTICATED

摘要

An authentication system includes a device to be authenticated and an authentication device. The device to be authenticated includes a first communication unit configured to transmit an instruction code and a first comparison value, and to receive a random number, a first memory unit, and a first control unit configured to create the first comparison value based on the random number, the common secret identification information and the instruction code. The authentication device includes a second communication unit configured to transmit the random number and to receive the instruction code and the first comparison value, a second memory unit, and a second control unit configured to generate the random number, create a second comparison value, compare the first comparison value with the second comparison value, and execute the instruction code when the first comparison value matches with the second comparison value.

1. Authentication system comprising:
a device to be authenticated including:
a first communication unit configured to transmit an instruction code for control of an authentication device and a first comparison value to the authentication device, and to receive a random number from the authentication device;a first memory unit which stores common secret identification information; anda first control unit configured to create the first comparison value based on the random number, the common secret identification information and the instruction code in response to a reception of the random number, and the authentication device including:
a second communication unit configured to transmit the random number to the device to be authenticated and to receive the instruction code and the first comparison value from the device to be authenticated;a second memory unit which stores the common secret identification information; anda second control unit configured to generate the random number in response to a reception of the instruction code, create a second comparison value based on the random number, the common secret identification information and the instruction code, compare the first comparison value which is received from the device to be authenticated with the second comparison value, and execute the instruction code when the first comparison value matches with the second comparison value.
