Abstract

The invention provides an Internet of Things system and a quantum key distribution method and device thereof. The Internet of Things system comprises an application layer, a sensing layer, a network layer and a quantum key management center, wherein the quantum key management center is used for analyzing a key request device and a target device from a quantum key request forwarded by an edge gateway of a sensing layer, and then judging whether the key request device and the target device belong to the same edge gateway or not; if so, indicating the edge gateway to allocate quantum keys in a key pool to the key request device and the destination device; otherwise, indicating the two edge gateways to which the key request device and the destination device belong respectively to distribute the quantum keys in the key pool to the key request device and the destination device respectively. According to the invention, the quantum key can be allocated to the equipment in the Internet of Things system, and the communication safety in the Internet of Things system is improved.

Description

technical field [0001] The present invention relates to the technical field of quantum keys, in particular to an Internet of Things system and a quantum key distribution method and device thereof. Background technique [0002] In a broad sense, the Internet of Things system can be regarded as a kind of "Internet" for information and data recognition and exchange between wide area networks / local area networks, people and targets that need to be recognized. The Internet of Things is the "Internet of Things Connected", which contains two meanings: first, the Internet of Things is an extension and expansion based on the Internet; second, its user end extends and extends to any object. In the face of various physical entities in the real world, smart terminal devices help the IoT system to realize the perception, collection, and timely or delayed analysis and processing of information data. The Internet of Things is now coming to ordinary consumers with a cheap and popular attit...
