Descrição: Although chaos based cryptology studies are an active research area, it does not make a significant contribution to the mainstream cryptology literature. Many design proposals have weaknesses. The most important reason is that the proposals are not adequately analyzed. For example, statistical tests such as NPCR and UACI are used in the analysis of chaos based image encryption algorithms. In this study it has been shown that these statistical tests can not be used as a security tool. Therefore, security analysis needs to reevaluate designs made with these statistical tests. A comprehensive analysis road map has been prepared to address this problem. An example of an analysis scenario is shown on a sample image encryption algorithm. The proposed analysis roadmap is intended to fill the lack of analysis in this area.
