Problems solved by technology

[0003] Among them, the bin file is the embedded device firmware compiled by the development tool, but it uses multiple files to open, which has poor confidentiality. At the same time, it needs to provide a programming address when upgrading, and the operability is poor.
At present, some manufacturers will encrypt the bin file, but the encryption method is fixed and easy to crack, and at the same time, the binary file has not been completely packaged.

Abstract

The invention provides an embedded device firmware security upgrading method and system, a terminal and a storage medium, and the embedded device firmware security upgrading method comprises the steps: setting an encryption algorithm library, and storing a plurality of encryption algorithms in the encryption algorithm library; randomly selecting an encryption algorithm from the encryption algorithm library as a primary encryption algorithm to perform primary encryption on an upgrade file, and encoding and packaging the primary encryption file and the primary encryption algorithm into a temporary file; randomly selecting an encryption algorithm from the encryption algorithm library as a secondary encryption algorithm to encrypt the temporary file, and encoding and packaging the encrypted file and the secondary encryption algorithm into an encrypted upgrade file; and sending the encrypted upgrading file to a terminal to which embedded equipment to be upgraded belongs, wherein the encrypted upgrading file is decrypted and decompressed by the terminal and then burnt to the embedded equipment to be upgraded. According to the embedded device firmware security upgrading method and system,the security of the firmware upgrading file can be improved, so that the security upgrading of the firmware of the embedded equipment is realized.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method, system, terminal and storage medium for safely upgrading firmware of an embedded device. Background technique [0002] The firmware upgrade of the embedded device is to use the serial port, USB or air interface to burn the compiled bin file into the device. [0003] Among them, the bin file is the embedded device firmware compiled by the development tool, but it uses multiple files to open, which has poor confidentiality. At the same time, it needs to provide a programming address when upgrading, so the operability is poor. At present, some manufacturers will encrypt the bin file, but the encryption method is fixed and easy to crack, and at the same time, the binary file has not been completely packaged. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method, system, terminal and storag...
