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
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
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,

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]
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 ...
