Abstract

The security of information, including image content, is an essential part of today's communications technology and is critical to secure transmission. In this paper, a new ROI-based image encryption algorithm is proposed that can quickly encrypt images with a security level suitable for environments that require real-time data transmission for images containing sensitive information such as ID cards. The proposed algorithm is based on one dimensional 5-neighbor cellular automata, which can be implemented in hardware and performed hardware-friendly operations. Various experiments and analyses are performed to verify whether the proposed encryption algorithm is safe from various brute-force attacks.

이미지 콘텐츠를 포함한 정보의 보안은 오늘날 통신 기술의 필수적인 부분이며 보안 전송에 매우 중요하다. 본 논문에서는 신분증 등 민감한 정보가 포함된 이미지에 대해 실시간 데이터 전송이 필요한 환경에 적합한 보안 수준으로 신속하게 이미지를 암호화할 수 있는 암호화 알고리즘을 제안한다. 제안되는 알고리즘은 하드웨어 구현이 가능하고, 하드웨어 친화적 연산이 가능한 1차원 5-이웃 셀룰러 오토마타를 기반으로 한 알고리즘이다. 제안된 암호 알고리즘에 대하여 다양한 실험과 분석을 수행하여 다양한 무차별 대입 공격으로부터 안전함을 검증한다.
