초록

최근 인터넷 환경에서 보안 서비스가 중요시 되면서 SSL/TLS의 사용은 행정기관뿐만 아니라 개인 홈페이지에서도 증가되고 있는 추세이다. 또한 IETF는 사물인터넷 환경에서도 제한된 성능과 자원을 가진 디바이스들이 보안기능을 위해 사용할 수 있도록 DTLS의 적용을 제안하고 있다. 본 논문에서는 LEA알고리즘을 구현하고 이를 OpenSSL 상에 적용 하였다. 그 결과 구현된 알고리즘은 AES 등과 같은 다른 대칭키 알고리즘들과 비교했을 때 연산 속도에 있어 우수한 성능을 보임을 확인 하였다.

Recently, A Security service in Internet environments has been more important and the use of SSL & TLS is increasing for the personel homepage as well as administrative institutions. Also, IETF suggests using DTLS, which can provide a security service to constrained devices with lower CPU power and limited memory space under IoT environments. In this paper, we implement LEA(Lightweight Encryption Algorithm) algorithm and apply it to OpenSSL. The implemented algorithm is compared with other symmetric encryption algorithms such as AES etc, and it shows the superior performance in calculation speed.
