Quantum Digital Signatures (QDS): A novel approach to safeguarding electronic health records

Bhavna Saini, Vivek Kumar Verma, Pradeep Kumar Tiwari +1 more

Electronic Health Records (EHRs) form the backbone of modern healthcare, ensuring seamless access to a patient’s medical history and fostering effective patient-doctor relationships. Their digital nature, however, exposes them to myriad security threats, including unauthorized access, tampering, and fraudulent alterations. Traditional cryptographic techniques, while effective in the current digital landscape, might not stand robust against future threats, especially those posed by quantum computers. This paper introduces Quantum Digital Signatures (QDS) as a cutting-edge approach to address this burgeoning concern. QDS leverages the principles of quantum mechanics to provide an additional layer of security, making it computationally infeasible for adversaries to forge or alter signed messages, including sensitive EHR data. Unlike conventional digital signatures that depend on the presumed difficulty of certain mathematical problems, the security attributes of QDS stem from the fundamental laws of quantum physics, ensuring a higher level of integrity and authenticity. We present a comprehensive overview of the QDS protocol and its integration into current EHR systems. Our comparative analysis with existing cryptographic techniques illuminates the advantages of QDS, especially in preventing undetected alterations and ensuring non-repudiation. Practical deployment challenges, including quantum device imperfections and potential integration bottlenecks, are also addressed. The adoption of Quantum Digital Signatures in safeguarding EHRs ushers in a new era of medical data security. While the large-scale implementation of such quantum technologies is still in its infancy, proactive research and early adoption are pivotal in preparing healthcare systems for future challenges. Through this research, we advocate for the broader integration of quantum cryptographic techniques, such as QDS, to uphold the sanctity and trustworthiness of electronic medical data in the face of evolving digital threats.

A Post-Quantum Digital Preservation and Secure File Sharing Framework for Library Repositories

Shanmugam Balachandran, S Sivankalai

Abstract Ensuring the long-term security and accessibility of digital resources is a critical challenge for libraries and archives. Traditional cryptographic methods, including RSA and elliptic curve schemes, are threatened by advances in quantum computing, which could compromise the confidentiality and authenticity of stored data. To address this, we present a Post-Quantum Digital Preservation and Secure File Sharing Framework that safeguards archival materials while enabling controlled user access. The framework integrates three core components: (i) a key encapsulation mechanism (KEM) for secure session key distribution; (ii) AES-GCM for efficient and file encryption; and (iii) digital signatures for authenticity verification. A dual-application design supports both repository operators and end-users: Repository operators encrypt, sign, and package digital assets into bundles, while users verify signatures, decrypt files, and restore content through a dedicated receiver GUI. Although the prototype employs X25519 and Ed25519 as placeholders, its architecture is fully compatible with NIST-standardized post-quantum algorithms such as Kyber (KEM) and Dilithium (signatures). By combining preservation with secure file sharing, the framework ensures confidentiality, authenticity, integrity, and resistance to quantum-era threats, offering a practical and forward-looking solution for Digital repositories.
