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

Embodiment 1

[0094] When used in the factory (such as image 3 shown), the identification and management of IoT devices in the factory are as follows:

[0095] When the device is assembled in the factory and enters debugging, the debugging software reads the ID data of the FLASH chip inside the IoT device. Based on the default MAC address and fixed IP address, the device activates 4G communication through the SIM card and sends the ID data to the data center. Server, the server generates the private key and ciphertext; and generates the device ID number of 1, 2, ..., n according to the order received; generates the MAC address reserved field data according to the random algorithm. The server packs these three types of information into overall data and sends it back to the IoT device. The IoT device forms a new complete MAC address according to the reserved field data configuration, and stores the device ID and ciphertext data in the FLASH chip. After the debugger completes the above steps...

Embodiment 2

[0098] When used in the field of application (such as Figure 4 shown), the identification and management of IoT devices on the application site are as follows:

[0099] When the IoT device is put into use on site, the application software will also read the FLASH chip ID data inside the device, combine the AES algorithm and private key to generate ciphertext, and compare it with the pre-stored ciphertext. If the comparison passes, it will be determined as a device efficient. If the device is valid, send the ciphertext and device ID to the central server to apply for communication access. The server queries the corresponding ciphertext according to the received device ID, and compares it with the received ciphertext. If the comparison is successful, the communication is allowed. After admission, IoT devices can transmit application data to the data center through established channels.

[0100] After the IoT device is used on site, the device automatically connects to the Be...

Embodiment 3

[0103] When used during the maintenance phase (such as Figure 5 shown), the identification and management of IoT devices in the maintenance phase are as follows:

[0104] During the use of the IoT device, when the device fails due to random hardware failure and is returned to the factory for repair, the identity information of the device needs to be maintained simultaneously. First of all, it is necessary to check whether the FLASH chip is damaged, and if it is damaged, update the FLASH. Use the device ID information backed up in EEPROM to find the identity data of the device in the data center server, update the ciphertext and re-apply for device access according to the new FLASH chip ID, and keep other information unchanged. If the EEPROM is faulty, the identity information stored in the FLASH needs to be backed up again in the replaced EEPROM.

[0105] Compared with the prior art, the IoT device identification method of the present invention has the following advantages ...
