Quantum-resilient cryptographic framework for cloud-based IoMT data in healthcare enterprises (H-ERPs)

The convergence of quantum computing and cloud-based IoMT poses significant security risks for healthcare enterprises. This paper proposes a Quantum-Resilient Cryptographic Framework to protect sensitive medical data. Key components include simulated annealing-enhanced key generation, quantum-robust distribution, and bi-directional identity-verified synchronization, achieving up to 32% time reductions. Quantum Attribute Encryption enhances access control by 45%, while blockchain ensures 99.8% data integrity with low processing latency. Experimental results show a 30% reduction in computational overhead, confirming the framework's efficiency and scalability. The proposed system offers a secure, enterprise-ready solution to safeguard IoMT data against classical and quantum threats in modern healthcare environments.
