Abstract

IMT-2000 mobile system will provide many application services such as mobile internet, wireless electronics commerce applications using air interface with high data rate. These applications require high data integrity, data confidentiality, user authentication, user identity confidentiality and non-repudiation. In this study, we analyze new security threats and air interface traffic performance for IMT-2000 mobile systems. Signal traffic for network access security services requires 0.2kbps~4.5kbps with the conditions of 246~768bits/massage, 0.2~1.0 basic services/sec and the security services of the rate 0.2~1.0 times compared with basic services.

IMT-2000 이동통신시스템에서는 빠른 전송속도의 지원으로 무선인터넷, 전자상거래 등 많은 응용서비스의 제공이 예상된다. 이들 서비스는 인증, 데이터 무결성, 데이터 암호화, 부인방지 등 높은 수준의 보안기능을 요구한다. 본 논문에서는 IMT-2000의 새로운 보안위협 요소를 분석하고 이에 따른 이동국과 기지국간 무선링크의 성능 분석을 수행하였다. 망 접속보안서비스의 지원에 필요한 무선구간의 신호트래픽은 평균메시지의 길이가 256~768bits, 기본서비스 대비 보안서비스 발생율이 0.2~1.0, 기본서비스의 발생율이 0.2~1.0서비스/호 인 조건에서 최소 0.2kbps에서 최대 4.5kbps로 분석되었다.
