Abstract

In the evolving healthcare landscape, securing electronic health records (EHRs) is essential due to increasing data breaches. This research introduces a solution using advanced cryptographic techniques and blockchain technology. The NTRU lattice-based cryptographic algorithm, known for its quantum resistance form the secure, quantum-resistant framework. Practical Byzantine Fault Tolerance (PBFT) provides low-latency finality and enhanced security. Privacy is ensured through zero-knowledge rollups on Polygon sidechains. To improve scalability, availability, and manageability, Docker is integrated with the blockchain platform and cloud services, facilitating powerful containerization. HIPAA compliance is achieved by adhering to the Privacy Rule, Security Rule, Breach Notification Rule, and Enforcement Rule. Key strategies include off-chain storage for Protected Health Information (PHI), encrypted communication, and robust access controls. The cloud infrastructure ensures secure, scalable, and efficient deployment, while cryptographic hashes and metadata are managed on the blockchain. This research significantly enhances the security and privacy of patient information, addressing a critical need in the healthcare sector.
