Problems solved by technology

[0004] According to the existing device-specific feature information writing technology, the device-specific feature information is easy to be tampered with, which will be used by some criminals
They can directly modify the relevant content through the above commands to change the proprietary features of the product, making the proprietary feature information of the device no longer accurate, making it impossible to accurately identify the identity of the device, and thus gain improper interests, causing great losses to equipment manufacturers

Embodiment Construction

[0032] In order to solve the problems of the prior art, the present invention proposes a method for preventing the device-specific feature information from being tampered with. By setting the verification of the corresponding identification mark, the illegal writing of the device-specific feature information is restricted, thereby preventing the device-specific feature information from being tampered with. Occurrence of illegal modification of feature information protects the legal benefits of equipment manufacturers.

[0033] In the technical solution proposed by the present invention, the device encrypts the information carried in the received device-specific feature information writing request through a preset information encryption algorithm, generates a corresponding matching identifier, and stores the matching The consistency judgment is made between the identification and the corresponding identification identification, and only when the contents of the two identificatio...

Abstract

The invention discloses a method and a device for preventing proprietary feature information of equipment from being falsified, which limit the illegal writing of the proprietary information of the equipment by carrying out encryption calculation on the corresponding information through a preset encryption algorithm before the information of the equipment is written in according to the consistency verification of a result of the encryption calculation and a corresponding identification mark so as to prevent from illegally altering the information of the equipment and protect the legal benefit of the equipment manufacturer.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for preventing device-specific feature information from being tampered with. Background technique [0002] In order to distinguish between devices, they usually store relevant proprietary feature information in the storage carrier of the device, so that they can be queried during production and after-sales. These proprietary feature information are generally written through related commands during production and processing. For example: write device name parameter command, where parameter is the content that needs to be written into the device-specific feature information. When using this command to operate in the device, the device-specific feature information content of parameter will be directly written into the storage carrier by the device, and the original content will be overwritten at the same time, so as to complete the writing or modificati...
