Abstract

최근 NFC(Near Field Communcation) 기반 통신 기능을 채용한 스마트기기 및 OS 등이 확산됨에 따라 기존 RFID를 이용하던 다양한 응용 분야에 대하여 NFC로의 대체가 진행되고 있다. 대표적으로 출입 통제나, e-ticket, 전자 결제 등의 분야에서 NFC가 RFID를 대체하고 있다. 기존의 RFID는 수동적 통신 기능만 제공하여 충분히 안전한 인증 및 권한 검증 방법을 제시하지 못하였으나, 능동형 통신기능을 제공하는 NFC를 활용하면 보다 안전한 인증 방식을 제공하여 다양한 응용에서 요구하는 보안 요구사항을 만족시킬 수 있다. 그러므로 본 논문은 NFC의 능동형 통신 기능을 활용하여 신용카드 결제, 출입통제 시스템 등에 활용될 수 있는 능동형 인증 방식을 제공할 수 있는 방법으로 EAP(Extensible Authentication Protocol)과 AAA(Authentication. Authorization and Accounting) 규약을 활용하는 방법을 제안한다. Since most of recently launched smart devices support NFC(Near Field Communication), RFID applications are tend to be replaced. For instance, previous RFID application areas such as entrance control, mobile e-ticket, electronic payment and et. al are subject to change using NFC. Due to the limitation of passive communication in RFID, it is impossible to cover all security requirements of authentication and authorization mechanism that wide areas of applications demand. Therefore authentication and authorization mechanism based on NFC is very attractive to such applications because active communication methods make it possible to be highly secure in authentication and authorization. In this paper, authors propose a new approach of secure authentication and authorization mechanism using NFC smart devices based on EAP(Extensible Authentication Protocol) and AAA(Authentication, Authorization and Accounting) protocols.
