The emergence of quantum computing has introduced unprecedented security
challenges to conventional cryptographic systems, particularly in the domain of
optical communications. This research addresses these challenges by
innovatively combining quantum key distribution (QKD), specifically the E91
protocol, with logistic chaotic maps to establish a secure image transmission
scheme. Our approach utilizes the unpredictability of chaotic systems alongside
the robust security mechanisms inherent in quantum entanglement. The scheme is
further fortified with an eavesdropping detection mechanism based on CHSH
inequality, thereby enhancing its resilience against unauthorized access.
Through quantitative simulations, we demonstrate the effectiveness of this
scheme in encrypting images, achieving high entropy and sensitivity to the
original images. The results indicate a significant improvement in encryption
and decryption efficiency, showcasing the potential of the scheme as a viable
solution against the vulnerabilities posed by quantum computing advancements.
Our research offers a novel perspective in secure optical communications,
blending the principles of chaos theory with QKD to create a more robust
cryptographic framework.Comment: 29 pages, 10 equations, 11 figure
