Secure Imaging in 6D Chaos: A DNA-Encoded Approach for Enhanced Privacy

Abstract

Images are encoded to prevent unauthorized access to sensitive data. Although chaos-based picture encryption algorithm is being widely utilized in many industries, the widespread use of low-dimensional chaos increases questions regarding the security of the encryption. The study suggests a framework for encrypting pictures that uses DNA Encryption and a 6D high-dimensional chaotic system to handle this. First, random chaos sequences are used to undergo diffusion and shuffling of the original image sequences, and then there is further diffusion and shuffling at the DNA level. An encrypted image is then created by combining the encoded sequences that are generated. The experiments' findings demonstrate that the recommended algorithm performs better in terms of picture complexity (key space over 2³⁰⁰), pixels correlations and image entropy (close to 8). Furthermore, in comparison to previous references, the algorithm demonstrates excellent encryption quality.
