Robust Long-Distance Quantum Key Distribution Using Proxy Encryption and Secure Cloud-Based Solutions

The secure communication system called Quantum Key Distribution (QKD) needs improvements in long-distance implementation because energy loss and eavesdropping threats exist. The authors present the Multi-layer Proxy Encryption Scheme (MPES) which combines proxy re-encryption together with entangled quantum particles to achieve security enhancements along with distant QKD transmission capability. Quantum repeaters within the MPES model conduct multiple encryption and decryption operations which guards fiber-optic channel data transfers. The trust-based shortest path algorithm enables more efficient photon transfer which leads to decreased transmission loss and improved efficiency. The experimental data shows that key errors decreased by 62.5% while energy efficiency increased by 90.90% when implementing the MPES against standard BB84 protocol operation. Optimal conditions for photon mean free path required keeping wavelengths at 0.0051 nm and determined the most efficient photon energy span to be between 0.01 MeV. The new modeling system enhances quantum communication protection and simultaneously achieves satisfactory key transmission speeds. The conducted research shows MPES presents itself as an effective solution for quantum-secure communication at extended ranges within cloud environments.

Deterministic quantum key distribution based on random phase coding

Lin Qing-Qun, Wang Fa-Qiang, Mi Jing-Long +3 more

We propose a new quantum key distribution scheme based on random phase coding. In this scheme, the sender and the receiver can share the secret information without basis reconciliation,and besides, this scheme is more efficient. As the phase of the qubit is coded randomly, this protocol is robust even when the source is not a prefect single photon. We show theoretically that it has higher security against the attacks, such as the photon-number-splitting, the impersonation attack, and the Trojan attack, etc., than the previous QKD scheme.

Time-bin encoding quantum key distribution in free-space horizontal links during nighttime and daytime

Sebastiano Cocchi, Domenico Ribezzo, Giulia Guarda +4 more

Free-space quantum key distribution (QKD) represents a groundbreaking advancement in secure communication, enabling secure key exchange over vast distances and offering robust encryption for the future quantum internet. However, the compatibility between fiber and free-space infrastructures continues to pose challenges for QKD protocols. Indeed, free-space and fiber-based networks commonly use different wavelengths and qubits encoding schemes. On the one hand, free-space QKD typically exploits visible light for its beneficial beam divergence compared with longer wavelengths, and polarization encoding for its robustness against turbulence. On the other hand, fiber-based QKD employs infrared light, particularly the C-band, because it shows the minimum losses with silica fibers, and time-bin encoding, due to polarization instability in optical fibers. In our study, we demonstrate the viability of a time-bin encoded QKD protocol operating in the C-band through horizontal turbulent free-space channels. We test the setup into a 50-m- and a 500-m-long link, respectively achieving an average secure key rate of 793 kbps and 40 kbps over several hours of measurements. The results encourage further exploration of the interoperability between free-space and fiber-based infrastructures, opening new possibilities for connecting terminal users with satellites in hybrid infrastructures.
