The USB flash drive is common used for portable storage. That is able to store large data and transfer data quickly and carry simply. But when you lose your USB flash drive without any security function in use, all stored data will be exposed. So the new USB flash drive supported security function was invented to compensate for the problem. In this paper, we analyze vulnerability of 6 control access program for secure USB flash drives. And we show that exposed password on communication between secure USB flash drive and PC. Also we show the vulnerability of misapplication for initialization. Further we develop a protection profile for secure USB flash drive based on the common criteria version 3.1. Finally, we examine possible threat of 6 secure USB flash drives and supports of security objectives which derived from protection profile.

IT 산업의 발전으로 인하여, 이동식 저장장치의 빠른 발전에도 불구하고, 대중적으로 사용되는 USB 저장 장치의 분실 및 탈취로 인한 민감 데이터의 노출 문제가 발생하였다. 이러한 문제점을 해결하기 위하여, 다양한 인증 방식을 적용한 보안 USB 저장장치가 등장하였지만, 소프트웨어의 구조적인 문제점으로 인하여, 사용자 인증정보를 검증하는 함수가 노출되는 것과 같은 인증 과정에서 발생하는 취약점을 악용함으로써, 보안 USB 저장장치에 안전하게 저장된 민감한 데이터를 보호하지 못하는 보안 위협이 발생하는 실정이다. 따라서 본 논문에서는 보안 USB 저장장치 중, F 제품을 대상으로, 지문 인증과정에서 발생하는 취약점을 분석하고 실증한다. 본 논문의 결과는 보안 USB 저장장치의 데이터 보호 및 인증기술을 더욱 안전하게 향상시키기 위한 참고 자료로 활용될 것으로 사료된다.

A USB flash drive is a portable storage device. For its promising moderate price, portability and high capacity USB flash drive users are increasing rapidly. Despite these advantages USB flash drives have critical problems as well. Such as personal information data leakage due to easy loss of the portable device. As these personal information leakage incidents increases various security measure solutions are produced and distributed. Despite these security measures and solutions it is not enough to perfectly protect personal data leakage. Hence the necessity of a more concrete, secure, user-friendly security measure solution is required. In this paper we provide you with portable USB flash drive security solution analysis and provide you with the latest secure, user-friendly security measure solutions.
