step S101, when receiving a certificate writing instruction, extracting the extended area information and the corresponding device identifier in the certificate writing instruction.

It should be noted that the certificate write instruction is to perform certificate extension on a standard certificate, so that custom setting can be performed in an extension area, for example, writing an equipment identifier in a custom extension area, so as to obtain an extended equipment certificate, thereby implementing personalized setting of the certificate, and improving flexibility of use of the equipment certificate.

Step S102, extracting the standard certificate information in the certificate writing instruction, and acquiring the certificate data structure information in the standard certificate information.

In this embodiment, when writing in a certificate, the certificate includes extended area information and a corresponding device identifier, that is, the extended area information and the device identifier written in the extended area information, and also includes standard certificate information when writing in a certificate, that is, the certificate is extended based on the standard certificate information, and generation of the certificate is not required again, and only the extension is performed on the basis of the standard certificate information, so that the efficiency of certificate generation is improved.

Step S103, according to the extended area information, extending the certificate data structure information to obtain extended standard certificate information.

In this embodiment, since the device identifier needs to be written in the device certificate, the identification of the device of the internet of things to be connected can be realized, that is, the device identifier is written in the extended area information in the extended standard certificate information, so that the identification of the device certificate is realized, for example, the OID written in the objectaltname in the extended area is 1.2.3.4.x.y, so that the device certificate with the device identifier is obtained, the limitation of the conventional device certificate is avoided, and the device information of the device of the internet of things to be connected can be more comprehensively displayed.

In an embodiment, before the step S103, the method further includes:

and when an extended area adjusting instruction is received, updating the extended area information according to the extended area adjusting instruction to obtain updated extended area information.

In this embodiment, as the parameter information of the device information is more and more, the more parameter contents that need to be written in the extended area, naturally, the requirement for the capacity of the extended area is brought, if on the conventional basis, only after the certificate is extended, the extended area is fixed and cannot be adjusted, but in this implementation, when an extended area adjustment instruction is received, the extended area information is updated according to the extended area adjustment instruction, so as to obtain updated extended area information, for example, when the extended area information is 10K, 10K can be adjusted to 15K according to the extended area adjustment instruction, thereby implementing flexible adjustment of the extended area.

The step S103 includes:

Further, before the step S104, the method further includes:

and when an equipment identification adjusting instruction is received, updating the equipment identification according to the equipment identification adjusting instruction to obtain the updated equipment identification.

In this embodiment, as more and more functions are supported by the device, when the device of the internet of things to be connected is upgraded, the functions supported by the device of the internet of things to be connected are different from the functions supported by the original device identifier, and under such a condition, the original device identifier cannot meet the device requirement of the current device of the internet of things to be connected.
