In this paper, an analyse of scientific journal articles related to chaotic cryptography from 2015 to 2021, is presented. In doing so, the study uses the Web of Science Core Collection database to analyze the data. 'biblioshiny' a web-interface of the 'bibliometrix 3.0' package of R-studio has been deployed to conduct bibliometric analysis. Also, a graphical mapping of the bibliometric material by using the visualization of similarities (VOS) viewer software, was developed. The study relies on the proposed approach to explore the influence of developing countries on Chaos-based encryption. We found out that developing countries are the most active on chaotic cryptography.
