Abstract

We propose an alternative design for quantum-safe network architectures, based on distributing certified randomness generated by different trust-level QRNGs. Our modular methodology aggregates high-trust entropy from upper network layers with local contributions, enhancing the security guarantees of locally available random sequences. Leveraging the physical guarantees of QRNGs and symmetric-key cryptographic algorithms for node authentication, our approach enables immediately deployable, quantum-safe infrastructures. Such a paradigm bypasses the practical security limitations of current QKD-based solutions, while avoiding massive key sizes and latency inherent to asymmetric PQC implementations.
