Breakthrough Study Unveils Quantum-Proof Cybersecurity for Telehealth
A pioneering study published in Blockchain in Healthcare Today (BHTY) unveils a
revolutionary cybersecurity framework designed to safeguard telehealth systems from the looming threat of quantum computing. Titled “Post-Quantum Cryptography Resilience in Telehealth Using Quantum Key Distribution,” the research introduces a novel architecture combining post-quantum cryptography (PQC), quantum key distribution (QKD), and advanced privacy-preserving technologies to secure patient data in the digital healthcare landscape.
The study, led by Don Roosan, PharmD, PhD, Associate Professor, Merrimack College, alongside researchers Rubayat Khan, PhD, University of Nebraska Medical Center, Saif Nirzhor, PhD, University of Texas Southwestern Medical Center, and Fahmida Hai, BSc, Tekurai, Inc, demonstrates how integrating quantum-safe encryption with blockchain and zero-knowledge
proofs can create an unprecedented shield against future cyberattacks.
By combining post-quantum cryptographic algorithms with quantum key distribution, authors lay the groundwork for a telehealth infrastructure that’s built to withstand nextgen cyber threats. The prototype was developed within a simulated telehealth network comprising hospitals, clinics, and patient devices.
Key innovations include:
- A Directed Acyclic Graph (DAG)-based ledger enabling high-speed, parallel transaction processing
- Quantum Key Distribution (QKD) channels for secure key exchange impervious to quantum
attacks
- Zero-Knowledge Proofs (ZKPs) and secure multiparty computation (MPC) to validate transactions without revealing sensitive data
- Attribute-Based Encryption (ABE) and smart contracts for precise access control over patient records
