MULTIPLE AUTHENTICATION SYSTEMS, MULTIPLE AUTHENTICATION METHODS, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an authentication device which authenticates multiple devices to be authenticated comprehensively.

SOLUTION: Multiple devices to be authenticated have a secret key S, while an authentication device generates a random number R and send the generated random number to the multiple devices to be authenticated. Then, an addition value of the IDs of the multiple devices to be authenticated which can be decomposed uniquely in relation to the addition is sought from the values received from the multiple devices to be authenticated, and the IDs of the multiple devices to be authenticated are identified from the addition value and authenticated.
