Post-quantum-inspired scalable blockchain architecture for internet hospital systems with lightweight...

Area of Science:

• Computer Science
• Cybersecurity
• Health Informatics

Background:

• Internet hospital systems and the Internet of Medical Things (IoMT) require secure, scalable, low-latency data management.
• Existing blockchain solutions struggle with high-frequency workloads and privacy demands in healthcare.

Purpose of the Study:

• To propose a post-quantum-inspired alliance blockchain architecture for Internet hospital systems.
• To address limitations in current blockchain infrastructure for real-time IoMT data management.

Main Methods:

• Developed a Kyber-inspired hybrid encryption simulation for faster data processing.
• Implemented a lightweight patient-centric access control mechanism with authorization proofs.
• Utilized a Raft-based consensus protocol for scalability and reduced latency.
• Integrated a fault-tolerant IoMT data ingestion layer with median filtering.

Main Results:

• Achieved significant reductions in encryption/decryption times (72.3%/74.4%) and consensus latency (92.3%).
• Demonstrated high sensor correction accuracy (90-96.2%) and low verification latency (∼0.002 ms).
• Showcased a fivefold increase in throughput, energy savings (9.4-12.3%), and lower memory usage compared to existing systems.

Conclusions:

• The proposed architecture offers a resource-efficient, trustworthy, and real-time solution for digital healthcare.
• It is deployment-ready in simulation environments, paving the way for next-generation healthcare ecosystems.
