Data security has become crucial in the current digital era, as a lot of important information is stored in digital form. One method that can be utilized in data security systems is chaotic systems, such as the Hadley chaotic system. The initial research in this paper involves the analysis of phase diagrams and bifurcation diagrams of the Hadley system, which is utilized as a random number generator for the XOR method to produce cipher data. This paper conducts an analysis to evaluate the effectiveness of the algorithm used for image encryption, including histogram analysis, correlation analysis, entropy analysis, sensitivity analysis, and noise attack analysis. The findings suggest that the Hadley system has the potential to be used as a data transmission masking technique based on the research findings. Numerical simulations using Python are conducted in this paper to support the research findings. It is expected that this research can contribute to enhancing communication security in the digital era.
