Quantum-resistant University Credentials Verification System on Blockchain

The production of fraudulent academic certificates has become a global issue. People with unethical thinking try to arrange fraud certificates to authorize themselves to exploit and access various high-end paying jobs and advance their careers. Therefore, this problem leads to identity masquerade. There are different blockchain-based solutions to store and validate these university transcripts and educational credentials, intended to provide decentralized exposure to the system. However, most blockchain-based system designs and platforms use pre-quantum cryptography on either public or private Blockchain and do not cover the whole ecosystem. The current systems cannot survive majority and quantum attacks. This paper uses Post Quantum Cryptography (PQC) powered Lattice-Based Cryptosystems and Hash-Based Signature (HBS) in the proposed system on a consortium-based blockchain solution to shield the distributed network from various attacks making it quantum-proof. The proposed system is indented to bring all the stakeholders under a well-defined process of issuance, recording, sharing, and verification of academic and professional educational credentials under a quantum-proof immutable distributed ledger to promote transparency and tamper-proofing to prevent ongoing frauds. The proposed system provides a better privacy mechanism, incorporates access and consent-based sharing control, secure from quantum and majority attacks and does not required any cryptocurrencies or tokens.
