QRQT Secures Teleportation Against Quantum Attacks via PQC, Limited by Quantum Memory to ~200 km
QRQT protects quantum teleportation's classical correction channel using post-quantum cryptography, eliminating classical attack vectors from quantum adversaries. Quantum memory coherence time (1 ms) bottlenecks security, capping secure distances at 191-199 km under fiber-optic conditions with varyi…
SDN-Orchestrated Hybrid Quantum-Safe IPsec Architecture Enables Scalable Banking Network Security
This paper proposes a hybrid quantum-safe IPsec framework for banking networks, integrating Classical Cryptography, Quantum Key Distribution (QKD), and Post-Quantum Cryptography via SDN-orchestrated key distribution in DMVPN environments. It addresses the quantum threat to RSA, DH, and ECC by enabli…
Collision-Free Quantum Money: Disproving Prior Schemes and Proposing Novel Unclonable Protocols
The paper demonstrates insecurity in the sole published public-key quantum money scheme, where a bank issues quantum states verifiable by all but clonable or forgeable by others. It introduces collision-free quantum money protocols, where even the bank cannot produce multiple identical-looking money…
