A Design of Secure Communication Architecture Applying Quantum Cryptography

Journal of Information Science Theory and Practice, 2022
Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short ...

Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Weak Randomness

Entropy, 2022
Sending-or-not sending twin-field quantum key distribution (SNS TF-QKD) has the advantage of tolerating large amounts of misalignment errors, and its key rate can exceed the linear bound of repeaterless quantum key distribution.

Full-field implementation of a perfect eavesdropper on a quantum cryptography system [PDF]

, 2011
Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its security is founded on the principles of quantum mechanics, but in reality it significantly relies on the physical implementation.

Measurement-device-independent quantum communication with an untrusted source [PDF]

, 2015
Measurement-device-independent quantum key distribution (MDI-QKD) can provide enhanced security, as compared to traditional QKD, and it constitutes an important framework for a quantum network with an untrusted network server.

Enhancing Quantum Key Distribution (QKD) to address quantum hacking

Procedia Technology, 2012
AbstractQuantum key distribution (QKD) is intended to produce cryptographic secret keys between two remote parties, usually called Alice and Bob. Even though QKD has been proven to be unconditionally secure against the eavesdropper, commonly called Eve, practical implementations of QKD may contain vulnerabilities that may lead to the generated secret ...
