This paper aims to develop SecureMedZK, a blockchain-based framework designed to secure Electronic Health Records (EHRs) using quantum-resistant encryption, privacy-preserving techniques, and HIPAA-compliant data management. The study integrates NTRU lattice-based cryptography, Zero-Knowledge Rollups, and Practical Byzantine Fault Tolerance (PBFT) to address scalability, security, and consensus issues. Performance evaluations were conducted through simulated environments, comparing SecureMedZK with traditional EHR systems on metrics such as scalability, latency, and security. The findings show that SecureMedZK significantly improves scalability by reducing on-chain transaction loads with Zero-Knowledge Rollups, resulting in a 30% improvement in transaction speed. PBFT ensures minimal delays even with increasing transaction volumes, while NTRU lattice-based cryptography offers quantum-resistant encryption, safeguarding EHRs against quantum threats. The system meets HIPAA standards with encrypted data storage, robust access controls, and immutable audit trails, proving its ability to provide secure and compliant healthcare data management. SecureMedZK has the potential for expanding secure healthcare data management, including genomic and imaging data, with future improvements in cryptographic techniques and consensus mechanisms.
