Securing the Medical Image Using Quantum Key Distribution and Henon Chaotic Maps
P. Bright Anna Bell and S Maria Celestin Vigila
The security of medical images in Internet of Medical Things (IoMT) is paramount due to increasing risks of cyber threats. However, while encrypting the image, face challenges such as vulnerability to brute-force and cryptanalysis attacks and scalability issues in large IoMT networks. Moreover, key distribution systems are prone to noise interference, photon number splitting attacks and high computational overhead. To overcome these challenges, this research introduces an Enhanced Quantum Secured key Exchange BB84 Protocol, integrating quantum cryptography with chaotic encryption. The methodology utilizes Quantum Key Distribution (QKD) augmented by Sparse Error Correcting Codes (SECC) for error correction and prevention of information leakage. The generated secure keys are used to initialize an improved Henon Chaotic (IHC) map which produces highly sensitive chaotic sequences for robust encryption. By combining the unpredictability of chaotic systems with the resilience of quantum cryptography, the proposed approach significantly strengthens the security and robustness of medical image transmission within the IoMT ecosystem, representing a major advancement in secure medical data communication.
