Abstract

Thanks to the development of 5G technology, the construction of edge data centers has been highly valued. In order to ensure the security of signal transmission in edge data centers, it is a promising measure to apply the quantum key distribution (QKD) technology to edge data centers. To solve the problem of noise interference in the process of applying QKD technology, this paper first proposes the edge-end quantum one-way edge data center architecture, that is, the edge data center that first distributes the data to the surrounding clusters, and then transmits the single data from the edge to the end. Directed quantum signals increase the safe communication distance to meet the requirements of information encryption. Secondly, we conduct research on the four-wave mixing (FWM)noise interference in the architecture and the secure key rate model of the QKD system and perform theoretical calculations of the noise power and the rate of the secure key. Finally, through simulation, we can evaluate that QKD has the characteristic of high degree of security and its performance is affected by channel location, classical signal power and QKD detection efficiency, etc. The FWM noise power increases first and then decreases with the increase of transmission distance, with the maximum distance of 15 km. When the distance between the classical channel and the quantum channel is more than 200 GHz, the effect of FWM noise on QKD is weak.
