Chaos-Based Color Image Encryption with DNA Operations
In this paper, an efficient yet simple color image encryption is proposed based on DNA sequence operation and chaotic maps for Android-based mobile devices. We designed our encryption algorithm based on such constraints. The main idea of the proposed method is different kind of DNA encoding for RGB channels and then Arnold’s cat map shuffling is performed in RGB channel in the combined manner. Then DNA addition is performed to diffuse the values between the RGB channels itself. Finally, DNA decoding is performed to form the color encrypted image. The promising feature of the proposed encryption algorithm is simple operations which comfortably suites for low processing power computing devices like Android mobile phones. The analysis and experiment’s results show the efficiency of the proposed encryption method.
