Embodiment 1

[0032] This embodiment is a method for secure transmission of Internet of Things data in a wireless harsh network environment. The process of the method is as follows: figure 1 shown. The system used in the method described in this embodiment includes: a smart device end, and the smart device end is connected to a measurement and control terminal through a wired network and a wireless network.

[0033] The smart device end can be various mechanical, electronic, electrical, chemical and other devices with or without sensors, such as: cameras that can perform three-dimensional rotation, robots, drones, and various smart home devices that can be connected to the Internet. Electrical appliances and other equipment. These devices can be simple sensors that can be operated remotely, such as cameras, which can be controlled remotely through the system. The lens of the camera can be rotated up and down, left and right, and monitor the surrounding environment in a wide range. It can ...

Embodiment 2

[0062] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding encryption. The encryption method described in "the step of encrypting the data code" and "the step of decrypting the data" described in this embodiment is an end-to-end one-way Hash function algorithm.

[0063]In this embodiment, an end-to-end encryption method is adopted to encrypt the transmitted data. Common data encryption methods mainly include symmetric encryption, asymmetric encryption methods, and hash algorithms. Since the operation speed of the asymmetric encryption algorithm is much slower than that of the symmetric encryption algorithm, when a large amount of data needs to be encrypted, the use of the symmetric encryption algorithm can increase the speed of encryption and decryption. At the same time, the symmetric encryption algorithm cannot realize the signature, and its key management is a complicated process. Therefore, this embodiment adop...

Abstract

The invention relates to a safe transmission method for data of Internet of Things under a wireless poor network environment. The safe transmission method for the data of the Internet of Things under the wireless poor network environment includes that gathering data; decomposing a data test packet; dividing the data test packet and passing back; decomposing the data; performing hierarchical data processing; carrying out network coding on the data; encrypting data codes; transmitting the data codes; comparing and regulating; decoding the data; performing hierarchical decoding; verifying; decoding the data. By means of the hierarchical coding technology, the data transmission error is effectively lowered, data transmission speed rates capable of automatically adapting to different networks enable the data completeness to be greatly guaranteed, and moreover, the network coding is combined with channel coding so that the network bandwidth resource consumption is saved, the spectral efficiency is improved, the network load is balanced, and the network robustness is improved; by means of the random multi-encryption transmission and self-adapting transmission efficiency, the spectral efficiency is effectively improved, the data transmission safety and stability are guaranteed under the poor network environment, and the transmission safety of the data of the Internet of Things is guaranteed under the premise of low cost.

Description

technical field [0001] The invention relates to a method for secure transmission of Internet of Things data in a wireless harsh network environment, is a computer wireless network data network processing method, and is a wireless data processing method for Internet of Things transmission. Background technique [0002] Existing IoT wireless transmission technologies include: Bluetooth wireless data transmission, wireless data transmission based on WiFi protocol, and wireless data transmission based on ZigBee protocol. The problem of Bluetooth as a wireless transmission of the Internet of Things is that the signal is susceptible to loss, which makes the output signal bandwidth rate low and more susceptible to external interference, thereby affecting the quality of signal transmission. The biggest problem with WiFi is that the security is very low, and the wireless stability of the product is relatively poor. Although ZigBee has the advantages of high security and low power co...
