ABSTRACT In today's mobile computing environment, there are many threats , such as device loss or theft, malware, to the sensitive information stored on end user device. To prevent disclosure of information, encryption and authentication method are properly adjusted to the device. In cryptographic file systems, CBC mode of operation has been commonly used. It requires an IV need not be secret, but must be unpredictable and protect integrity of the IV. In this paper, we propose file system-level encryption mechanism with HSM that satisfy the requirement of the IV and improve the performance. Moreover, Design and experimental results prove the efficiency of our proposed method.Keywords: CBC Mode, IV, File System-Level Encryption, HSM I.서 론 최근 ICT(Information and Communication Technology)의 발전에 따라, 전산 업무 환경은 사무실내 유선 네트워크와 데스크탑 PC를 사용하는 고정된 형태에서 무선 인터넷과 소형 모바일 디바이스를 사용해 언제 어디서나 업무가 가능한 모바일 오피스 접수일(2013년 6월 17일), 게재확정일(2013년 7월 26일)* 본 연구는 방위사업청과 국방과학연구소가 지원하는 국방위성항법연구센터 사업의 일환으로 수행하였습니다.†주저자, [e-mail]‡교신저자, [e-mail] (Corresponding author)
