On the Image Encryption Algorithm Based on the Chaotic System, DNA Encoding, and Castle

Hundreds of image encryption algorithms have been developed for the security and integrity images through combination DNA computing chaotic maps. This two instruments is not sufficient enough to thwart potential threats from cryptanalysis community as literature review suggests. To inject more robustness stuff, a novel scheme has written in this research by fusing system, Castle —a chess piece. As plain input, its pixels are shifted scrambled at randomly chosen pixel addresses. scrambling realized routine called Image Scrambler using (ISUC). moves on hypothetical large chessboard. Pixels taken addresses image, where lands each iteration. After scrambled, it encoded. Two mask also Then throw diffusion effects cipher, Addition XOR operations between encoded data conducted. Next, converted back into their decimal equivalents. Four dimensional system used get vectors. The hash codes given SHA-256 function cipher introduce plaintext sensitivity design. We got an information entropy 7.9974. Simulation carried out machine, thorough analyses demonstrate good effects, defiance varied attacks community, bright prospects some real world application proposed cipher.
