Embodiment 1

[0020] Such as figure 1 As shown, a kind of encrypted transmission method based on quantum random number to the Internet of Things security described in this embodiment, the specific steps are as follows:

[0021] The first step: through the quantum true random number generator, the generated random number is stored as a password book in the server database for the server to read and stored in the external memory of the hardware end for the hardware end to read, and the hardware end and The server end stores the same identification code to the password book; wherein the length of the password book is greater than 256 bytes.

[0022] Step 2: The hardware side initiates a connection verification to the server through the identification code. After receiving the verification request and confirming the pass, the server obtains two sets of codebook subscript random number sequences that meet the length of the codebook, and one group is encrypted. The key password book subscript ra...

Abstract

The invention relates to the technical field of Internet of Things transmission, in particular to an encryption transmission method for Internet of Things security based on a quantum random number, which comprises the following steps of: 1, a random number generated by a quantum true random number generator is taken as a cipher book, and the same identification code for the cipher book is stored at a hardware end and a server end; 2, after receiving the verification request, the server obtains two groups of cipher book subscript random number sequences from the quantum true random number generator; step 3, the hardware end replces the two groups of cipher book subscript random number sequences with an encryption key and a serial number query key according to the array subscript of the cipher book; 4, when the data is sent, the sending end encrypts the transmission data channel; the receiving end decrypts the received data; and 5, if the transmission sequence number does not correspondto the server, the transmission sequence number is re-acquired through the sequence number query key. According to the encryption transmission method for the Internet of Things security based on the quantum random number, the transmission security of the Internet of Things can be ensured, the performance requirement on an MCU is reduced, and the power consumption requirement is reduced.

Description

technical field [0001] The invention relates to the technical field of Internet of Things transmission, in particular to an encrypted transmission method for Internet of Things security based on quantum random numbers. Background technique [0002] With the continuous research and development of sensor technology and the continuous development of the Internet of Things, how to ensure the secure communication between the server and the hardware is a current research hotspot, so as to realize encrypted data transmission, prevent data leakage, and prevent the hardware from being maliciously controlled. Whether it is the Internet-connected smart devices that users usually use, or the IoT monitoring equipment and control equipment used by the company government, there is an urgent need for the security of the Internet of Things, especially in today's society where the Internet of Things is ubiquitous, to ensure the data security of the Internet of Things, It is one of the focuses...
