mCoupon NFC Ultra-Lightweight NFC Authentication System and method for mCoupon Service

摘要

The present invention relates to an ultra light NFC authentication system and method for an mCoupon service, which includes installing coupon software through OTA communication with an authentication server, issuing a mobile ID, and performing coupon management by acquiring access rights to a kit storage unit in a Secure Element And a short range wireless communication unit for exchanging random ID information of the user, coupon information, and approval information with the NFC tag and the store on the short distance wireless communication, The coupon software is installed in the coupon service communication unit using the NFC mobile terminal, the ID is issued from the authentication server, and the coupon is issued through the rot () table generated through the Seed value distributed beforehand between the NFC tag and the authentication server The information is newly updated. According to the present invention, since the arbitrary ID information of the user is arbitrarily changed by the hash calculation, it is safe because the user ID can not be acquired even if the attacker exposes the medium in the middle, Even if the coupon information is exposed, the occurrence of financial damages can be prevented. In addition, since it performs only simple shift and XOR operations, it is very efficient in the amount of computation.
