Simulation and analysis of a QKD-PQC protocol for secure communication channel authentication

G. K. Sandhia, M Ranjani, Srivatsan K +2 more

Quantum computing threatens traditional cryptographic systems based on integer factorization and discrete logarithm problems. This paper proposes a hybrid secure communication framework integrating Quantum Key Distribution (QKD) with Post-Quantum Cryptography (PQC) for authentication. The BB84 protocol is used for quantum key generation, while CRYSTALS-Dilithium signatures secure the classical communication channel. A Python-based simulator models photon transmission, Quantum Bit Error Rate (QBER), intercept-resend attacks, and authentication verification. Results show that QBER increases proportionally with eavesdropping probability, enabling reliable attack detection. The integration of QKD secrecy with PQC authentication ensures both confidentiality and integrity. Performance evaluation demonstrates that the additional latency introduced by PQC authentication remains within acceptable limits. The proposed hybrid framework provides a scalable and quantum-resistant solution suitable for next-generation secure communication systems.

On the Key Search Complexity in Quantum Cryptography with Strong Information-Theoretic Authentication

S. P. Kulik, S. N. Molotkov

The stability of quantum key distribution systems is based not only on the detection of attacks on quantum states, which is guaranteed by the fundamental quantum theory laws, but also on ensuring the integrity of classical messages transmitted through an auxiliary classical communication channel. To detect attacks on the classic communication channel, the authentication procedure is used. Information-theoretic authentication guarantees the detection of attacks on the classical communication channel regardless of the computational and technical capabilities of an eavesdropper, including the quantum computer. The fundamental quantum cryptographic relationship between the abstract criterion of the robustness of quantum key distribution systems with theoretical-information authentication and the quantum key search complexity has been determined for the first time using simple means.
