This paper describes a technique that encrypts images in the form of DNA sequences using PWLCM system, i.e., Piecewise Linear Chaotic Map. This method has two times DNA-encoding–decoding operations along with DNA-permutation and DNA-diffusion operations to get the cipher image. On comparison with other processes, the advantage of this algorithm is easy to compute but confuses a cryptanalyst a lot. Apart from that dual-layer DNA-encoding–decoding processes in the algorithm result in good encryption outputs. When outputs are subjected to different security analysis to find out the strength of the algorithm, results with encrypted images with higher values of UACI, NPCR, key space, information entropy, and good correlation coefficient. This results in strong resistivity toward widely used attacks.
