Embodiment 1

[0050] Such as figure 1 As shown, the embodiment of the present invention provides a digital certificate offline secure distribution method for NB-IoT terminal equipment, including:

[0051] S101: Log in to the IoT cloud platform through the IoT platform user client, perform a product creation operation on the IoT cloud platform, and obtain a user identification code authorized by the IoT cloud platform;

[0052] S102: Add the NB-IoT terminal device and its corresponding device identification ID to the created product through the IoT platform user client;

[0053] S103: The IoT cloud platform synchronizes the user identification code and the device identification ID to the security service platform, so that the security service platform generates the ciphertext of the digital certificate file of the NB-IoT terminal device according to the user identification code and the device identification ID;

[0054] S104: Operate on the IoT cloud platform through the IoT platform user c...

Embodiment 2

[0057] On the basis of the above-mentioned embodiment 1, the present invention provides another method for offline secure distribution of digital certificates of NB-IoT terminal devices, including:

[0058] S201: Log in to the IoT cloud platform through the IoT platform user client, perform a product creation operation on the IoT cloud platform, and obtain a user identification code authorized by the IoT cloud platform;

[0059] S202: Add the NB-IoT terminal device and its corresponding device identification ID to the created product through the IoT platform user client;

[0060] S203: The IoT cloud platform synchronizes the user identification code and the device identification ID to the security service platform;

[0061] S204: The security service platform generates the ciphertext of the digital certificate file of the NB-IoT terminal device according to the user identification code and the device identification ID, specifically including:

[0062] S2041: The security serv...

Embodiment 3

[0078] On the basis of the above-mentioned embodiment 2, the difference from embodiment 2 is that in the embodiment of the present invention, the ciphertext of the digital certificate file is decrypted on the production line PC, and the decrypted digital certificate file is filled with To the corresponding NB-IoT terminal equipment, including four application scenarios, refer to figure 2 The working processes of the four application scenarios are introduced respectively.

[0079] The first application scenario: filling a digital certificate file of an NB-IoT terminal device on the PC of the production line, and the digital certificate file of the NB-IoT terminal device only needs one filling operation;

[0080] The second application scenario: filling a digital certificate file of an NB-IoT terminal device on the PC of the production line, but the digital certificate file of the NB-IoT terminal device needs multiple filling operations;

[0081] The third application scenario...

Abstract

The present invention provides a method and system for offline secure distribution of digital certificates of NB-IoT terminal equipment. The method includes: logging in to the IoT cloud platform through the IoT platform user client, performing the operation of creating a product on the IoT cloud platform, and obtaining a user identification code authorized by the IoT cloud platform; adding NB‑ to the created product through the IoT platform user client The IoT terminal device and its corresponding device ID; the IoT cloud platform will synchronize the user ID and device ID to the security service platform, so that the security service platform can generate a digital certificate for the NB‑IoT terminal device based on the user ID and device ID File ciphertext; operate on the IoT cloud platform through the IoT platform user client, choose to download the ciphertext of the digital certificate file of the relevant NB‑IoT terminal device, and transmit the ciphertext of the downloaded digital certificate file of the NB‑IoT terminal device offline To the production line PC, for decrypting the ciphertext of the digital certificate file on the production line PC, and filling the decrypted digital certificate file into the corresponding NB-IoT terminal device.

Description

technical field [0001] The present invention relates to the technical field of secure communication, in particular to a method and system for offline secure distribution of digital certificates of NB-IoT terminal equipment. Background technique [0002] In the era of the Internet of Everything, information interaction and communication between people and things and things and things can be realized through the Internet of Things, so as to obtain a more convenient life experience. As NB-IoT is officially incorporated into the 5G standard and becomes the core technology of the mMTC (Massive Machine Type Communication) scenario, the application of NB-IoT technology will develop faster, and the issue of network information security also poses new challenges to its development. In the scenario where a large number of NB-IoT terminal devices are connected to a unified IoT cloud platform, all kinds of collected data are transmitted through the NB-IoT network, and there is a risk of...
