| description | Due to the advancements in the field of quantum
computing and possible compromise of existing key-exchange
algorithms, it is essential to explore performance and efficiency of
new key-exchange techniques, such as Quantum Key Distribution
(QKD). QKD is possible over fiber cable and Free Space Optical
(FSO) links. Fiber based QKD may be used if direct line of sight
link is not possible, but it brings along many problems related to
material properties of fiber cable and detector limitations. It is
therefore more convenient to use free-space based QKD
whenever physically possible. Furthermore, FSO links can be
satellite-supported in order to generate worldwide distribution of
quantum keys. The FSO however greatly depends on weather
conditions and link length, thus it is very important to evaluate
these effects on the size of quantum key. In this paper,
simulation-based evaluation of FSO QKD is done given tropical
weather conditions specific for Malaysia. The paper discusses
how different factors, such as link distance, weather, beam
intensity and transceivers setup, influence key size when BB84
QKD protocol is used. For each weather condition specific for
Malaysia key size was obtained, and the percentage of the
received key compared to the total generated key is calculated.
The results show the size of the final encryption key after being
transmitted over FSO channel influenced by various weather
conditions, which implies that it is possible to use FSO based
QKD in Malaysia successfully. |
