Abstract
Facing the increasing need of data transmission security, encrypting data through cryptography is a key solution. In an industrial Internet of things, cryptography based on quantum key distribution provides perfect secrecy with lower resource requirements of both computational power and storage compared with traditional cryptography. To explore how to deploy this technology, this paper proposes an industrial Internet of things network architecture embedded with quantum key distribution systems, combines it with the noise model of spontaneous Raman scattering and the evaluation model of quantum key distribution systems theoretically, simulates the performance in a normally used industrial environment, and works out instructions to the deployment of the raised architecture. The results also show that a better choice to avoid performance descending is to duplicate classical channels and quantum channels with the same direction instead of moving classical channels backward, while noises have the strongest influence at the transmission distance of 25 km.
