Colored Image Encryption Algorithm Using DNA Code and Chaos Theory

DNA computing and Chaos theory introduce promising research areas at the field of Cryptography. In this paper, a stream cipher algorithm for Image Encryption is introduced. The chaotic logistic map is used for confusing and diffusing the Image pixels, and then a DNA sequence used as a one-time-pad (OTP) to change pixel values. The introduced algorithm shows also perfect security as a result of using OTP and good ability to resist statistical and differential attacks.
