Therefore, with this paper, we present a new encryption approach based on chaotic outputs to insure more protection. This approach combines two encryption techniques in addition to random permutation. The first one consists to put in disorder binary data and the second technique is based on conditional logical function. The choice between those two techniques is perfectly random and generated from chaotic outputs. Each process has her own keys which make the encryption more complicated.1120202111202021939715https://www.naun.org/main/UPress/ami/2021/a302013-015(2021).pdf10.46300/91014.2021.15.15https://www.naun.org/main/UPress/ami/2021/a302013-015(2021).pdfUniversity of nevada reno department of science & engineering.
