Abstract: ABSTRACT OF THE INVENTION QUANTUM-ENHANCED CLOUD COMMUNICATION SYSTEM USING HYBRID QKD AND CRYPTOGRAPHIC KEY MANAGEMENT FOR SECURE DATA EXCHANGE A quantum-enhanced cloud communication system integrates hybrid Quantum Key Distribution (QKD) protocols with cryptographic key management for secure data exchange between cloud-connected entities. The system comprises quantum-enabled cloud endpoints having hybrid QKD modules, cryptographic key management units, and classical communication interfaces. The hybrid QKD module combines discrete-variable QKD and continuous-variable QKD protocols, selectively activated based on channel conditions. A cryptographic key management unit derives session keys by combining quantum-derived key material with post-quantum cryptographic key encapsulation mechanism output, ensuring security if either component remains uncompromised. A quantum key relay infrastructure comprising trusted nodes and quantum repeaters extends key distribution over extended distances. An intrusion detection module monitors quantum bit error rate and channel anomalies to detect eavesdropping, triggering key revocation upon anomalous conditions. The system provides quantum- resistant secure data exchange for cloud applications including encrypted storage, secure multi-party computation, and authenticated cloud service communication.
