Abstract

The invention discloses a firmware upgrade method, device and system thereof. The method comprises obtaining secret key and judging whether the obtained secret key is same as the target secret key or not, wherein the target secret key is used for opening the writing bus channel between the communication module and multiplexer to upgrade the firmware which is solidified in the target hardware, and the communication module and multiplexer are both installed on the target hardware. If obtained secret key is same as the target secret key, the target secret key is utilized to open the writing bus channel to upgrade the firmware. The firmware upgrade method, device and system thereof solve the technical problem of low safety when the firmware upgrades in upgrading process in the related art.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a firmware upgrading method, device and system. Background technique [0002] Firmware upgrade is an important way to improve firmware performance. It refers to improving the working program or source code in the hardware through a special upgrade program to improve compatibility, performance or function. This kind of upgrade can continuously improve the performance of the machine and continuously bring out the potential of the host system. However, if the firmware upgrade (or flashing) has no encrypted security control, there is a great risk. The biggest risk is that hackers maliciously modify or Misuse of the upgrade will cause the system to fail to work. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a firmware upgrade method, device, and system to at least solve ...
