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.
