DEVELOPMENT OF A NEW METHOD FOR IMAGE ENCRYPTION USING DNA SEQUENCE AND CHAOTIC MAP

With the fast development of computer and network technologies, people’s communications have been greatly changed. Transmission for digital multimedia content over Internet has become more and more frequently. However, the security of multimedia has a serious threat in the process of transmission due to the openness and sharing of networks. So people have to take more and more attention on security and confidentiality of multimedia information.

As a good encryption algorithm, it should resist from all kinds of known attacks such as exhaustive attack, differential attacks, and statistical attacks. Basically, it should be sensitive to the secret keys, and the key space should be large enough to resist brute-force attacks. Current available techniques still not heavily resist to such attacks.

This project aimed is to develop a secure image encryption scheme by combining a chaotic map's approach with a DNA sequence to increase security level.
