Problems solved by technology

In addition, the MAC method can be verified offline, and can solve problems such as network load in large-scale installations, but in this case, it is necessary to provide the RFID reader with a secret key for verification

Embodiment 1

[0026] First, the outline of this embodiment will be described.

[0027] In this embodiment, information for verifying the validity of the ID information, that is, part of the verification value or the signature value is used as the ID, thereby ensuring the validity of the ID information with a small amount of information. Here, in order to ensure legality with less information, in this embodiment, the Schnore signature, which is one of the representative electronic signature methods, is used for description. By transforming the Schnore signature by using the remainder operation, an electronic signature method with a shorter signature length can be realized.

[0028] In addition, ID information and the like are uniquely determined. Specifically, the ID issuing device sets parameters used in the signature method, and the ID issuing device calculates the electronic signature of the present invention for a specific message. Then, a part of the signature value is written as an I...

Abstract

A portion of a digital signature value for authenticating the validity of ID information is also used as an ID so as to reduce the amount of data. This is achieved by using a digital signature scheme with a short signature length obtained by transforming a Schnorr signature, which is a typical example of a digital signature scheme.

Description

technical field [0001] The invention relates to the legality assurance technology of ID information and the generation and verification of electronic signatures. Background technique [0002] RFID (Radio Frequency Identification: radio frequency identification) is to exchange information through short-range radio communication using radio waves or the like based on tags embedded with ID information, and is used for logistics management and circulation of food and goods, etc. areas, IC tickets to transportation facilities, employee ID cards, student ID cards, etc. [0003] In addition, use for security purposes such as identification of counterfeit products and counterfeit products by attaching RFID tags to genuine products is also expected. In the case of such use for security purposes, it is desirable to have a mechanism for distinguishing whether or not the RFID tag itself is an RFID tag manufactured by a legitimate RFID tag manufacturing company. [0004] In the convent...
