Abstract

The application provides an FPGA embedded terminal device bit stream attack detection method, device and electronic equipment, the method comprising: obtaining the image data of the bit stream data received by the FPGA embedded terminal device; determining the data frame segmentation granularity, and segment the image data based on the segmentation granularity to obtain a plurality of data frames; generate a bit stream attack feature set corresponding to the image data based on the plurality of data frames; The bit-stream attack feature set and the known bit-stream attack feature set are used to detect the bit-stream attack on the FPGA embedded terminal device. This method can improve the detection rate of bitstream attack on FPGA embedded terminal equipment.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a method, device and electronic equipment for bitstream attack detection of FPGA embedded terminal equipment. Background technique [0002] FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array) is a large-scale programmable digital integrated circuit, which can be reprogrammed by end users to realize the semiconductor device of the required digital system. It emerged as a semi-custom circuit in the field of ASIC (Application-specific Integrated Circuit, application-specific integrated circuit), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of original programmable device gates Combined with short time-to-market, low non-recurring engineering overhead, and high flexibility. [0003] With the rapid development of semiconductor technology and IC (Integrated Circuit, app...
