Abstract

Radio Frequency Identification(RFID) has been considered as an key infrastructure for the ubiquitous society. However, due to the inherent drawbacks, RFID causes var- ious security threats like privacy problems, tag cloning, etc. This paper analyses the security risk analysis process from the perspective of the RFID tag life cycle, identify the tag usage process, identify the associated vulnerability and threat to the confidentiality, integrity and availability of the information assets and its implications for privacy, and the mitigate the risks.

RFID 는 유비쿼터스 환경하에서 필수불가결한 기술이 되도 있다. 그러나 RFID 의 본질적인 단점으로 인하여 프라이버시와 같은 보안적인 취약점을 기자고 있다. 따라서 본 논문에서는 RFID 시스템의 관점하에서 태그에서의 보안적인 취약점 및 이럴 해결하기 위한 여러 가지의 프로토콜에서의 문제점을 분석하였다. 최근에는 반도체 공정 기술의 발전과 경량화프로토콜의 발전으로 인하여 태그에서의 보안성이 향상되고 있는 중이다.
