Post Quantum Cryptography on Healthcare Security: Safeguarding Patient Data in Medical Systems

Shubham Kumar Kumar

Quantum computers are capable of solving problems that classical computers cannot, particularly in the realm of cryptographic algorithms such as RSA, DSA, and ECC. Post quantum cryptography refers classical cryptographic algorithm that are designed to secure sensitive data. This research explores the application of post-quantum cryptographic techniques in healthcare systems, with a specific focus on integrating Quantum Key Distribution (QKD) with Genetic Algorithms (GA) for enhanced key optimization. As quantum computing advances, traditional cryptographic systems employed in health care are more and more vulnerable to being broken. Security of sensitive patient information—like electronic health records (EHRs), diagnostic data, and personally identifiable information— requires strong solutions that can handle future quantum attacks. Post-quantum cryptography (PQC) provides a hopeful way forward by employing quantum computer-resistant algorithms. This paper investigates the deployment of PQC methods—e.g., lattice-based, hash-based, and multivariate polynomial cryptography—inside healthcare systems to improve data confidentiality, integrity, and availability. It assesses the weaknesses of present encryption technologies and introduces PQC as a necessary update to protect patient information from sophisticated cyberattacks. The study also addresses the interoperability, computational overhead, and infrastructure readiness challenges of implementing PQC in healthcare. By implementing quantum-resilient cryptographic protocols, healthcare facilities are able to future-proof data protection practices and guarantee the safeguarding of patient data in an era governed by quantum computing.

Quantum-Enhanced Data Security for Electronic Health Records: A Framework for Post-Quantum Cryptography in Healthcare Systems

R. Balamanigandan, Sai Srinivas Vellela, Shobana Gorintla +3 more

In digital healthcare systems, there has been an upsurge in the utilization of Electronic Health Records (EHRs) which is raising some concerns on data privacy and security, particularly following the quantum computing innovation. RSA and ECC encryption services, which are the traditional mechanisms, are expected to be rendered useless in light of quantum algorithms, like that of Shor and Grover, which can break classical cryptographic algorithms. This paper introduces a framework of quantum enhanced data security to solve these vulnerabilities, in which Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD) are integrated. The suggested model uses the lattice-based encryption (Kyber), post-quantum digital signature (Di lithium), and QKD to secure key exchange. A comparative simulation to classical encryption approaches manifests that the model with innovative frameworks provides the high levels of resilience toward quantum penetrations, a better authentication accuracy and a slight augmentation of access durability. It indicates that the combination of PQC and QKD could be a scalable, persistent, and future-proof solution to the security of sensitive healthcare information under next-generation cyberattacks.

Post-quantum cryptographic policy frameworks for medical institutions

With the progress of quantum computing, medical institutions that use classical public-key cryptography to secure the confidentiality of long-lasting and delicate healthcare information are facing great security challenges.This research aims to suggest a policy framework for Post-Quantum Cryptographic Policy (PQCP) to facilitate systematic shift of healthcare infrastructures to quantum resistant infrastructure security.It seamlessly combines cryptographic asset discovery, quantum-risk assessment, asset prioritization, cryptoagility, hybrid cryptographic migration, secure key management, governance, compliance monitoring, and ongoing security evaluation.It covers electronic health records, healthcare platforms in the cloud, medical imaging, telemedicine applications and resource-limited Internet of Medical Things devices.A risk-oriented migration strategy gives institutions the ability to prioritize systems based on the amount of data in a system, the vulnerabilities of the cryptographic functions used, the clinical criticality of the system, and the length of time the information must be kept confidential.There are hybrid (classical and post-quantum) mechanisms for gradual migration and interoperability or clinical continuity.Finally, the suggested framework offers a structured approach to enhance the preparedness of healthcare institutions, adherence to regulations, resilience against cryptographic attacks, and long-term protection of healthcare information from the evolving quantum cybersecurity landscape.
