A new color image encryption scheme based on DNA sequences and multiple improved 1D chaotic maps
A DNA-based color image encryption method is proposed by using three 1D chaotic systems with excellent performance and easy implementation. The key streams used for encryption are related to both the secret keys and the plain-image. To improve the security and sensitivity, a division-shuffling process is introduced. Transforming the plain-image and the key streams into the DNA matrices randomly can further enhance the security of the cryptosystem. The presented scheme has a good robustness for some common image processing operations and geometric attack.
