IoT device identification method, system, device and computer readable medium

Abstract

The present invention relates to a method, system, equipment and computer-readable medium for identifying an Internet of Things device. The method includes the following steps: acquiring chip ID data inside the Internet of Things device in real time; generating a public key, a private key and a private key according to the acquired chip ID data Ciphertext data; send the private key and ciphertext data back to the IoT device, the IoT device forms a new complete MAC address according to the reserved field data configuration, and stores the IoT device ID and ciphertext data in the chip; obtains the IoT device in real time The verification information of the device, according to the verification information of the IoT device, query the IoT device ID and ciphertext data stored in the corresponding chip, and compare it with the received ciphertext. If the comparison is successful, it is determined that the device registration is successful. The invention is suitable for users' state collection and control of various agricultural objects in digital agriculture, and also for equipment suppliers to form a large database through self-organization, providing data analysis and processing platforms for various application software developers or users.

Description

technical field [0001] The present invention relates to the technical field of identification of agricultural Internet of Things equipment, in particular to a method, system, equipment and computer-readable medium for identification of Internet of Things equipment. Background technique [0002] With the rapid development of digital agriculture, various solutions for crop seed storage, real-time monitoring and control of crop growth, and traceability management solutions for agricultural products all use the Internet of Things to integrate different types, regions, and stages through node devices. The information is analyzed and processed centrally. These IoT devices will exchange data with the central server in a wireless manner. [0003] At present, digital agriculture solutions are more and more integrated, and more and more node devices need to be managed at the same time; users hope to connect nodes and LANs in different periods to a unified data center; they also hope ...

AI Technical Summary

Problems solved by technology

As long as the node device obtains the server address from the user, it can exchange information with the data center. This method causes the data center to passively receive invalid data or even illegal data; more seriously, it may even download core data and confidential data from the server in an unauthorized way. , resulting in information security incidents

[0007] 2) The unique management method of node device identity code is complex

In order to ensure the uniqueness of the identity codes of massive node devices in the data center, it is necessary to continuously perform back-end processing through manual maintenance during use, which is inefficient, poor in inheritance, prone to errors and leads to repeated codes, resulting in loss and confusion of data calls

[0008] 3) The physical addresses in the network are not uniformly planned

With the increase of node devices, due to the lack of unified management, it is easy to cause Ethernet MAC address conflicts, resulting in communication loss or congestion

[0009] 4) The identification information and inherent feature information of IoT devices are not bound for management

However, in the current system, only the manually defined device number is used as the identity information, and the identity information related to other devices is transferred to the application layer, which is reorganized, summarized and matched by the application software, which not only increases the repeated overhead of the application software , it is also easy to cause the loss, error or inconsistent matching of these binding information, which directly affects the application analysis

[0010] 5) It is easy to lose the identity code information when the equipment is repaired due to failure

If an IoT device breaks down and enters for repair, if the fault point is the identity information storage chip, the original manually set identity code will be lost directly; Identity code information lost
