초경량 블록암호 알고리즘이 적용된 RFID 시스템

This paper presents an RFID system for monetary applications and for privacy protection. The proposed system comprises a security database server, RFID readers and tags. An ultra light weight cryptic algorithm has been implemented on the RFID tag to get a sufficient level of secrecy. Only the authorized RFID readers can identify the RFID tags with keys shared among the security database server and tags.
