High information redundancy and strong correlation of neighboring pixel values are characteristics of encryption methods like DES (Data Encryption Standard), AES (Advanced Encryption Standard) and other traditional data encryption methods. There is a need for more robust methods to overcome these challenges. This paper discusses an image encryption method that uses DNA encoding rules to improve image security and combination of 3D chaotic maps like Lorenz, Rossler, Chen and Lu systems to create unpredictable sequences using chaotic dynamics. First, the image is divided into its RGB color channels, and then DNA rules are used to encode each RGB channels. Using a key derivation function, a secure key is generated from the image content to modulate the chaotic sequences. The chaos systems are utilized to create chaotic sequence. Sequence scrambling and XOR operations improve security even more. After that, an encrypted image is obtained and saved. Using the key, the chaotic sequences are recreated during decryption, and the original image is recovered by repeating the process in reverse.
