Internet of Things gateway data encryption communication method based on quantum random number key

Abstract

The invention discloses an Internet of Things gateway data encryption communication method based on a quantum random number key, relates to the technical field of data encryption, and solves the technical problem of low data encryption efficiency based on a quantum key in the prior art. According to the method, to-be-encrypted data is divided based on encryption efficiency, index tags are set for a plurality of sub-data through quantum random numbers, an encrypted data sequence is generated through sequential rearrangement and integration, and finally the encrypted data sequence is encrypted through a quantum key; according to the method, the quantum key only needs to be generated once for the same to-be-encrypted data, the quantity demanded for the quantum key is small, and the data encryption efficiency can be improved; according to the method, the to-be-encrypted data is analyzed based on the quantum encryption efficiency, the to-be-encrypted data is segmented according to the set rule, and the to-be-detected data is encrypted once through the quantum random number and simple reordering; according to the invention, the to-be-encrypted data is encrypted twice, so that the data encryption quality can be improved.

Description

technical field [0001] The invention belongs to the field of data encryption, and relates to a quantum random number key-based data encryption communication technology for the Internet of Things, in particular to a quantum random number-based data encryption communication method for the Internet of Things. Background technique [0002] The issue of information security has been paid more and more attention by people. Various data encryption devices and software are used in data protection to provide protection for data security. Most of the keys used in these encryption technologies come from random numbers, so quantum Random numbers are widely used in the field of data encryption. [0003] In the prior art, when encrypting gateway data by quantum random numbers, the quantum key not only needs to encrypt the data to generate an encryption key, but also needs to encrypt the encryption key, so that the demand for quantum keys increases, and the When the gateway data is encryp...

Problems solved by technology

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; for this reason, the present invention proposes a method for encrypted communication of IoT-related data based on a quantum random number key, which is used to solve the problem of using quantum random numbers in the prior art When encrypting data, the demand for quantum keys is large, and there is no necessary processing for the data to be encrypted, resulting in the technical problem of low data encryption efficiency. The present invention divides the data to be encrypted based on the encryption efficiency, and uses quantum random numbers to divide the data into several sub-data Set the index label, generate an encrypted data sequence through sequential rearrangement and integration, and finally encrypt the encrypted data sequence with a quantum key, and send the obtained encrypted data to solve the above problems
