Practical Security of High-Dimensional Quantum Key Distribution with Intensity Modulator Extinction

open access: yesEntropy, 2022
Quantum key distribution (QKD) has attracted much attention due to its unconditional security. High-dimensional quantum key distribution (HD-QKD) is a brand-new type of QKD protocol that has many excellent advantages. Nonetheless, practical imperfections

Security analysis of measurement-device-independent quantum conference key agreement with weak randomness

open access: yesFrontiers in Physics, 2023
Quantum conference key agreement (QCKA) allows multiple users to distribute secret conference keys over long distances. Measurement-device-independent QCKA (MDI-QCKA) is an effective QCKA scheme, which closes all detection loopholes and greatly enhances ...

Post-Quantum Cryptography [PDF]

open access: yesNature, 2011
Cryptography is essential for the security of online communication, cars and implanted medical devices. However, many commonly used cryptosystems will be completely broken once large quantum computers exist. Post-quantum cryptography is cryptography under the assumption that the attacker has a large quantum computer; post-quantum cryptosystems strive ...
