QEdu: A Quantum-Safe Blockchain Framework to Secure and Verify Educational Credentials
Abu Taher Md Shifat, Md. Ahsan Habib, Shahid Hasan, Avishek Roy · 2023
Distributed Ledger Technologies (DLT), notably blockchain, have advanced significantly, finding applications in various domains, including education, for enhanced transparency and accountability. The utilization of hash functions and public-key cryptography (e.g., ECDSA and RSA) in blockchain ensures these attributes. However, the rapid progress in quantum computing has unveiled vulnerabilities in classical public-key cryptography, necessitating a reassessment of blockchain architecture for quantum resistance. This article explores diverse blockchain architectures in education, evaluating their susceptibility to quantum attacks. It introduces QEdu, a consortium blockchain framework securing educational credentials using quantum-safe Elgamal-Like public-key cryptography based on matrices over grouping. Comparative analysis with existing works underscores the efficacy of the proposed framework.
