Abstract

The embodiment of the invention discloses a firmware protection method and device for embedded equipment of Internet of Things, equipment and a medium. The method comprises the steps of generating a first calculation result according to at least one hardware identifier ID through Boot firmware, and storing the first calculation result to a preset position; starting business firmware, and reading the first calculation result; generating a second calculation result according to the at least one hardware identifier ID through the service firmware; and comparing the first calculation result with the second calculation result, and executing a corresponding firmware protection operation according to a comparison result. By utilizing the method, the firmware can be effectively protected from being copied or plagiarized, so that the security of the firmware is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of firmware security, and in particular, to a firmware protection method, device, device, and medium for embedded devices in the Internet of Things. Background technique [0002] With the continuous development of embedded devices such as Internet of Things gateways, copy boards often occur, such as firmware being copied or plagiarized. Firmware can refer to programs written in embedded devices, which can be understood as solidified in embedded devices. The software program code inside an integrated circuit that controls and coordinates the functions of the integrated circuit. At present, a mature copy board industry chain has even been developed in the market, which can copy the products of other manufacturers 1:1 through the firmware copy method, paste their own brand and sell them, and shoddy them as good ones, so as to influence the embedded device sales market. A harmful effect wa...
