혼돈신호에 따른 암호화 정도 분석

다국어 초록 (Multilingual Abstract)

The Chaotic system using encoding methods has seen a great deal of research being conducted in data communication and image encoding. For more effective encoding methods, researchers have created a complicated chaotic system, and employ the signals generated from the said system in encoding. In the study, it was identified that variation of probability distribution which appears in the time series, a used signal in the chaotic system, has a big impact on the efficiency of encoding. In order to present this impact in a numerical mode, a correlation coefficient of data following encoding was calculated with the subsequent image encoding. In this paper, we propose that the method is a new effective encryption algorithm as well as easily application one.
