Quantum key distribution (QKD) is a secure communication method implementing a cryptography protocol involving the theory of quantum mechanics. It allows two entities to generate a shared random secret key known only to them. This secret key can then be used to encrypt and decrypt messages on the respective ends of the communication. Many researches have been conducted on different aspects of the same and researchers came up with the celebrated BB84 protocol. The protocol presents a way of exchanging the secret keys using the polarizations of photons. This paper introduces an application of QKD for a railway track monitoring system backed up with IoT sensors. An approach toward simulation of quantum key distribution between an IoT device and a server to encrypt the data sent to the server is discussed in the paper. It also demonstrates the simplicity of this method and its efficiency in producing a QKD simulation. Also, it is demonstrated that for the IoT security, the quantum key length thus generated is used.
