With the rise of quantum technologies, data security increasingly relies on quantum
cryptography and its most notable application, quantum key distribution (QKD). Yet, current …

Practical implementations of quantum key distribution (QKD) protocols can introduce
additional degrees of freedom in the quantum states that may render them distinguishable to …

Quantum key distribution (QKD) theoretically offers unconditional security. Unfortunately, the
gap between theory and practice threatens side-channel attacks on practical QKD systems …

Abstract Quantum Key Distribution (QKD) offers unconditional security in principle. Many
QKD protocols have been proposed and demonstrated to ensure secure communication …

Intensity modulation/direct detection (IM/DD) optical key distribution (OKD) is a method to
generate a secret key whose security against passive eavesdropping is guaranteed by the …

Modern quantum key distribution (QKD) network designs are based on sending photons
from one node to another and require free-space or dedicated fiber optic cables between …

Abstract Quantum Key Distribution (QKD) systems are thought to be the best method for
securing data in cloud storage and boosting security and privacy. Due to the increasing use …

Linear-feedback shift register (LFSR) based pseudo-random number generator (PRNG) has
applications in a plethora of fields. The issue of being linear is generally circumvented by …

In theory, quantum key distribution (QKD) provides unconditional security; however, its
practical implementations are susceptible to exploitable vulnerabilities. This investigation …

Practical implementations of QKD protocols involve devices which are not perfect, and an
eavesdropper may exploit this to gain information leading to attacks. Here we have …
