Secure Data Storage in The Cloud by Using DNA and Chaos Cryptography

Encryption is a technique for securing and protecting images against unauthorized access. Security is a major concern in everyone's life, and encryption plays a critical part in ensuring it. Because of the digital world, it is now incredibly easy to hack any information stored in the cloud. Many picture encryption techniques are based on chaotic logistic maps, but they have drawbacks such as limited key space and insecure security. In this research, we present an image encryption approach based on chaotic logistic mapping and Deoxyribose Nucleic Acid (DNA) encoding. The analysis results reveal that the proposed scheme has an acceptable level of security, efficiency, complexity, and speed.
