Abstract

This study is a file management security system that encrypts and decrypts computer and cloud data by using Bluetooth based cryptographic module. It is a necessary solution in terms of abuse of personal information and protection of social and national information. We developed H/W and S/W for SFMS(: Safe File Management Security) related Bluetooth module in cloud environment and implemented firmware development, encryption key generation and issuance, client program for system mobile and key management system. In the terminal internal encryption and decryption, SFMS was developed to ensure high security that the hacking itself is not possible because key values exist separately for each file.

본 연구는 블루투스 기반의 암호모듈을 활용하여 전산기 및 클라우드 데이터를 암 복호화하는 파일관리 보안시스템으로 개인정보의 오남용과 사회적, 국가적 정보보호 측면에서 반드시 필요한 솔루션이다. 클라우드 환경에서 SFMS(; Safe File Management Security) 관련 블루투스 암호모듈에 대한 H/W와 S/W를 개발하여 펌웨어 개발과 암호키 생성 및 발급, 시스템 모바일용 Client 프로그램, 키 관리 시스템 등을 적용하였다. 단말 내부 암 복호화는 파일별로 키값이 별도로 존재함으로 해킹 자체가 원천적으로 불가능 한 높은 안전성을 확보할 수 있는 SFMS 개발하였다.
