Problems solved by technology

[0003] In the production process, in order to burn the firmware into the chip, it is necessary to obtain the firmware in advance. However, if the firmware itself does not have a protection mechanism, this method will easily lead to the firmware being copied, and the production process has certain security risks.

Abstract

The invention discloses a method for preventing firmware copying by burning a firmware signature. The method comprises the steps that the firmware signature is generated for to-be-burnt information through an encryption algorithm; the information is stored to be burnt and the firmware signature into firmware; the burning information and the firmware signature are written into a chip by a burning tool; the firmware verifies the firmware signature through the encryption algorithm; and when the signature is passed, the firmware works normally. Compared with the prior art, the method has the following advantages that the firmware signature information is additionally burnt for the module, then when the module is started, the firmware has the signature verification function, when verification succeeds, the firmware works normally, otherwise, verification fails, and it is indicated that the firmware or the module may be burnt successfully through other abnormal production processes, and thefirmware cannot work normally. Therefore, when the firmware is copied, the firmware cannot be operated normally, and the security of the firmware is improved.

Description

technical field [0001] This application relates to the field of intelligent module production, in particular to a method for preventing firmware copying by burning firmware signatures. Background technique [0002] With the rise of the Internet of Things and the advancement of technology, there are more and more networking module products. Networking modules have been more and more widely used in various fields because of their advantages of intelligence and convenient use. In the production of such products, it is generally necessary to burn the firmware into the chip. The burning process needs to be downloaded from the server or offline. The firmware file is obtained by exporting, and then imported into the burning tool, and then the firmware is burned into the chip through the burning tool. [0003] In the production process, in order to burn the firmware into the chip, it is necessary to obtain the firmware in advance. However, if the firmware itself has no protection m...
