Internet of Things communication system based on quantum technology

Abstract

The invention discloses an Internet of Things communication system based on a quantum technology, and the system comprises an Internet of Things terminal, a U-key and a cloud platform. The cloud platform comprises an encryption center, secret keys are pre-stored in the U-key and the encryption center, the U-key obtains a to-be-encrypted message of the Internet of Things terminal for encryption, and sends the encrypted message and the secret key serial number to the Internet of Things terminal through a U-key interface; the Internet of Things terminal receives the encrypted message and the secret key serial number, and sends the encrypted message and the secret key serial number to the cloud platform; and the cloud platform extracts a secret key pre-stored in the encryption center according to the secret key serial number to decrypt the encrypted message to obtain a plaintext message. According to the method and the device, the secret key is stored in the U-key, and when the Internet of Things terminal and the cloud platform carry out data interaction, the secret key in the U-key is adopted to carry out data encryption, so that ciphertext transmission is realized. The technical problem that the safety is poor by adopting a preset key and issuing the key through a short message is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Internet of Things communication system based on quantum technology. Background technique [0002] With the continuous evolution of urban intelligence and digitalization, IoT applications are becoming more and more popular. Correspondingly, more and more attention has been paid to the control and coordinated operation of large-scale IoT devices, as well as the possible serious consequences of loss of control. The security of the Internet of Things will increasingly become one of the basic problems that people need to solve. In order to realize the security of the exchanged data between the IoT terminal and the IoT platform, the exchanged data is usually encrypted. [0003] At present, the encrypted transmission of data between the IoT terminal and the IoT platform usually adopts the following methods: First, the IoT terminal and the IoT platform negotiate a key in adv...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides an IoT communication system based on quantum technology to solve the problem of encrypting and transmitting data between IoT terminals and IoT platforms in the prior art by using preset keys and passing The method of sending the key by short message will make the key easy to leak, which is a technical problem with poor security.
