Approach to optical encryption: merging ghost imaging with chaos theory

This paper presents what we believe to be a novel optical encryption algorithm that utilizes ghost imaging based on orthogonal patterns and is combined with chaos theory to improve the security of the encrypted image. The encryption process is carried out in two stages: the first is ghost imaging, while the second utilizes chaos theory. The random sequences generated by chaos theory are integrated with the orthogonal ghost imaging bucket data, effectively protecting the encrypted images from unauthorized access. In this research, the simulation of the proposed encryption algorithm was performed using Logistic mapping. The results of the analysis confirm the efficacy of the proposed encryption algorithm. Additionally, the experimental results are consistent with the simulation findings, supporting the validity of the method. This consistency emphasizes the success of the proposed encryption approach, highlighting its theoretical soundness and future applicability in ideal or well-controlled optical settings. While not yet optimized for deployment in noisy communication environments, the architecture offers a solid conceptual foundation for future adaptation in practical systems.
