Abstract

The embodiment of the invention provides an Internet of Things device component version information extraction method for MIPS architecture. The method comprises the following steps: collecting Internet of Things device firmware, and determining a component binary string of an Internet of Things device based on the firmware; determining a binary character string with version information of the Internet of Things device based on the component binary character string; and determining component version information of the Internet of Things device based on the binary character string with versioninformation, wherein the component version information comprises a component version number and a component version name. According to the method provided by the embodiment of the invention, automaticextraction of the component version information of the Internet of Things device is realized, and the component version information extraction efficiency of the Internet of Things equipment can be improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things devices, in particular to a method for extracting component version information of Internet of Things devices for MIPS architecture. Background technique [0002] With the widespread application of IoT technology, the number of IoT devices is also increasing year by year. The open source components used in IoT firmware pose new challenges for IoT device security. With the increasing number of open source components, in order to better analyze the firmware, it is necessary to accurately collect firmware and component information in the firmware. Therefore, component version analysis has become a top priority in firmware security analysis. [0003] In general, the version information of the component can be obtained by running the component when the device is actually running or simulated running. However, due to different types of devices, the firmware simulation depends on the ...
