COLOR PICTURE ENCRYPTION BY USING DNA ENCODING: A COMPREHENSIVE REVIEW

Abstract

Due to the rapid advancement of the Internet and network, information security has become a major issue in encryption. Therefore, a growing and significant issue is the development of the encryption algorithm. A new color image encryption based on DNA complementary rules and pairing chaotic maps was implemented in this research. The plain color image was initially divided into three components (R, G, B) and converted using DNA encoding rules into three DNA matrices. Secondly, through the pair of chaotic maps, DNA addition for R, G and B components was introduced and the element position of three DNA sequences was scrambled. The restructuring of the R, G, and B components achieved three grey coded images and RGB encrypted images. The experimental outcome and safety analysis simulation showed that this algorithm had greater secret key space and high secret key sensitivity and had an excellent ability to resist statistical and differential attacks.
