Abstract

The invention discloses a firmware upgrading method and device. The method comprises the following steps of obtaining a target firmware file used for upgrading a firmware; determining first summary information according to summary data recorded in the target firmware file; extracting a summary of a manufacturer firmware content recorded in the target firmware file to obtain second summary information according to a preset digest algorithm; comparing the first summary information and the second summary information; and if the first summary information is consistent to the second summary information, utilizing the target firmware file to upgrade the corresponding firmware of a hardware device according to hardware device identification information recorded in the target firmware file. Through application of the technical scheme provided by the embodiments of the invention, the potential safety hazard brought to a kernel due to firmware upgrading through the unreliable firmware file can be avoided, and the security of a computer system is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a firmware upgrading method and device. Background technique [0002] In a computer, firmware, namely firmware, is usually stored and solidified in the EEPROM (Electrically Erasable Programmable Read-Only Memory) or FLASH chip of the hardware device, which bears the lowest and most basic work. [0003] Firmware can be regarded as the programming of hardware devices, which determines the working performance of hardware devices. As the design level of hardware devices gets higher and higher, firmware becomes more powerful and complex. In practical applications, there may be bugs in the firmware, or the corresponding firmware parameters need to be changed due to different application scenarios, all of which need to be resolved through firmware upgrades. [0004] In the Linux system, the kernel supports the online upgrade of the firmware, by obtaining and loading the firmware fi...
