QHCP: Quantum-Resilient Hybrid Cryptographic Protocol for Secure Data Exchange in Next-Generation Networks

Abstract

As the next-generation networks are developed, the demands for secure, reliable, and future-proof protocols for data exchange are greater than ever. Traditional cryptographic protocols remain susceptible to seemingly futuristic low-risk, high-reward advancements of commercial quantum computing. We exhibit a novel protocol named QHCP: Quantum-Resilient Hybrid Cryptographic Protocol, which combines the post-quantum resiliency from several post-quantum cryptographic algorithms with efficiency gained from maintaining the use of classical protocols to ensure data remains confidential and/or the integrity of data remains intact over time. The architectural style that QHCP uses is a Layered approach: Performance (ap­plication layer) to Quantum Resistance (crytographical superfluous services). In addition to it, QHCP solves practical issues such as hygienic key handling for minimizing potential risks introduced by cyber breaks and low-latency cycles that are perfect for working in fast, resource-limited environments. On a first glance, we find reasonableness of the security soundness/efficiency trade-offs and range for how (on next-to-future-internet-of-things (of) things systems to) on the future bigger computing infrastructures under 6th generation (6g)) farities of use can possibly be supported by QHCP! All-in-all, QHCP offers a strong path for making the sensitive data minimum quantum-protected through hybrid quantum-classical model resistant to diverse evolving advanced cyber threats.
