Color Image Encryption Using LFSR, DNA, and 3D Chaotic Maps

One of the most important challenges facing researchers is to find new methods protect data sent over Internet and prevent unauthorized access it. In this paper, we present a method for encrypting image divided into two stages. The first stage requires redistributing positions pixels by using key random numbers generated linear feedback shift registers then deoxyribonucleic acid rules. in previous encrypted again chaotic maps increase level security second stage. Several statistical tests were implemented verify efficiency proposed compare results with work other researchers. proved reasonable safety rate compared techniques.
