Abstract

In this paper, an optical encryption system using binary key code based on the joint transform correlator (JTC) is considered. The binary key code is synthesized by using a design technique of the pixel-oriented Computer Generated Holograms (CGHs). The independence and efficiency of the binary encryption key are investigated through computer simulation. To test the efficiency of the encryption system using binary key code, a holographic encryption system is constructed, and the experimental results prove that our holographic encryption system has high ability.

Joint transform correlator(JTC)를 기반으로 이진 암호화 키를 사용하는 광 암호화 시스템을 제시하였다. 이진 암호화 키는 Pixel-oriented CGH의 설계방법을 이용하여 제작하였고, 컴퓨터 모의 실험결과를 통하여 구현된 이진 암호화 키의 독립성 및 효능을 조사하였다. CGH방법으로 구현된 이진 암호화 키의 효능을 검증하기 위하여 홀로그래픽 메모리 기반의 광 암호화 장치를 구성하여 실험을 하였으며 그 결과 높은 암호화 가능성을 나타내었다.
