In today’s digital era, ensuring the security of data has become increasingly important due to the vast amount of crucial information stored in digital formats. The Rikitake chaotic system offers a potential solution for data security. This study focuses on investigating the Rikitake system through the analysis of its phase diagrams, time series, bifurcation diagrams, and Poincare maps. The system’s chaotic behavior is harnessed as a random number generator, serving as a key in the XOR method to generate encrypted data. The effectiveness of the algorithm for image encryption is assessed through various analyses, including histogram analysis, correlation analysis, entropy analysis, sensitivity analysis, and noise attack analysis. The findings indicate that the Rikitake system can be effectively utilized as a technique for masking data transmission. The paper includes numerical simulations conducted in Python to provide supporting evidence for this proposition.
