Problems solved by technology
[0004] 1) The maintenance terminal of a PC or device is usually not a security device, which may store outdated configuration data version information, which may cause the configuration data version information displayed on it to be inconsistent with the version information read back;
[0005] 2) Even if the displayed configuration data version information is consistent with the one read back, there is a risk of human error in the manual confirmation link, for example, the data version configured on the device is wrong and the wrong version information has been maintained by the PC or The terminal reads back and displays correctly, but if the error is manually confirmed, it will also cause the wrong version of the data to be run on the device;
[0006] 3) Even if the data version information is correct, the data may not be configured on the correct device. For example, there are multiple same devices in a distributed system, but each device needs to be configured with different data. At this time, there is a data configuration risk of error

Embodiment Construction
[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0050] On the one hand, the present invention uses a security algorithm to generate the check word, and stores it in a special device. On the other hand, the above feature information is written into the configuration data. Check word, after configuring the data, in the process of device initialization, use the same algorithm to generate the check word online from the feature information written into the configuration data, and then compare it w...

The invention relates to an allocated data automatic verification method based on encryption equipment feature information, in which checksums are generated from the equipment feature information through the security algorithm, and the consistency between the checksums is determined through comparison so that whether data allocated to equipment is correct or not can be judged. The method specifically comprises the following steps: 1) generating an offline checksum; 2) adding the feature information to the data to be allocated; 3) generating an online checksum; and 4) carrying out online checking: the imported checksum is compared with the checksum which is generated in an online manner, initialization is successful if the checksums are consistent, and the initialization fails if the checksums are not consistent. Compared with the prior art, the method provided by the invention has the advantages that the work efficiency is improved, risks caused by human interference are avoided, and the like.
Description
technical field [0001] The invention relates to an automatic verification method for configuration data, in particular to an automatic verification method for configuration data based on encrypted device feature information. Background technique [0002] In a distributed system, the running devices need to update the configuration data frequently according to user requirements. In order to confirm the correctness of the updated configuration data on the device, the version information of the configuration data is usually read back on the PC or the maintenance terminal of the device. Then manually confirm it. [0003] Disadvantages of the above method: [0004] 1) The maintenance terminal of a PC or device is usually not a security device, which may store outdated configuration data version information, which may cause the configuration data version information displayed by it to be inconsistent with the version information read back; [0005] 2) Even if the displayed confi...
