OTQuSbox Framework: A Quantum-Assisted Session-Based S-Box Construction With Secure Seed Synchronization

2026 · IEEE Access

Conventional Substitution-boxes (S-boxes) used in symmetric-key cryptography are typically static or generated through deterministic pseudo-random processes, making them vulnerable to long-term structural analysis, precomputation, and learning-based cryptanalytic attacks. To address these limitations, this paper proposes …
