Abstract

An e-passport is equipped with bio information by adding the non-attachable IC chip with a smart function. In order to solve such a problem, the user's privacy is protected by using the BAC, PA, AA and EAC mechanisms. However, the password key used in the BAC mechanism is made of the combination of the MRZ values. As a result, it is possible to decode the password by using the indiscriminate attacking program after finding out the combined rules of MRZ. This thesis suggests the mechanism with an improved level of efficiency through the time-stamp values by using the information of images and fingerprints and checking the forge or falsification of the e-passport when establishing a safe channel between the chip of the e-passport and the decoding system.

전자여권은 기존의 여권정보에 비접촉식 스마트 기능의 IC칩을 추가하여 바이오 정보를 탑재한 것으로 전자여권의 보안 위협으로부터 보호하기 위해 BAC, PA, AA, EAC 메커니즘을 사용하고 있다. 그러나 BAC 메커니즘에 사용되는 암호 키는 MRZ 값들의 조합으로 만들어 지기 때문에 MRZ 조합규칙을 알아낸 후 무차별 공격 프로그램을 사용하여 암호 해독이 가능한 단점이 있다. 본 논문은 전자여권 칩과 판독시스템간의 안전한 채널 형성 시 해시된 이미지 정보와 지문 정보를 이용하여 전자여권의 위 변조를 확인하고 타임스탬프 값을 통하여 효율성이 향상된 메커니즘을 제안하였다.
