Practical Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Frequency Side Channels

open access: yesApplied Sciences, 2021
The twin-field quantum key distribution (TF-QKD) and its variants can overcome the fundamental rate-distance limit of QKD. However, their physical implementations with the side channels remain the subject of further research.

Measuring security practices

open access: yesCommunications of the ACM, 2022
Users are encouraged to adopt a wide array of technologies and behaviors to reduce their security risk. However, the adoption of these "best practices," ranging from the use of antivirus products to keeping software updated, is not well understood, nor is their practical impact on security risk well established.

Joint photon-number splitting attack on semi-quantum key distribution

open access: yesFrontiers in Physics, 2022
Semi-quantum key distribution is based on the basic principle of quantum mechanics, which allows a classical user and quantum user to use information theory to have a secure shared key.

Security of quantum key distribution with source and detection imperfections

open access: yesNew Journal of Physics, 2021
In practice, the device imperfections might introduce deviations from the idealized models used in the security proofs of quantum key distribution (QKD). This requires the refined security analysis for practical QKD. However, in most of previous analysis,

Quantum Hacking on an Integrated Continuous-Variable Quantum Key Distribution System via Power Analysis

open access: yesEntropy, 2021
In quantum key distribution (QKD), there are some security loopholes opened by the gaps between the theoretical model and the practical system, and they may be exploited by eavesdroppers (Eve) to obtain secret key information without being detected. This

Prudent Practices in Security Standardization [PDF]

open access: yesIEEE Communications Standards Magazine, 2021
From June 2019 to March 2020, IETF conducted a selection process to choose password authenticated key exchange (PAKE) protocols for standardization. Similar standardization efforts were conducted before by IEEE (P1362.2) and ISO/IEC (11770-4). An important hallmark for this IETF selection process is its openness: anyone can nominate any candidate; all ...
