Vulnerability mining method of charging pile operating system based on blemish analysis and fuzzy test

Electric vehicle charging pile is one of the energy Internet entrances, carrying the important missions of charging power supply, charging metering and charging, vehicle charging safety and charging data interconnection, etc. According to the characteristics of its embedded operating system, an improved fuzzy testing method based on blot analysis is proposed. The method firstly analyzes the attack surface of the firmware from the Angle of vulnerability exploitation, then derives the corresponding security rules according to the attack surface, carries on the stain analysis, and finally generates the fuzzy test case set according to the results of the stain analysis.
