A state monitoring device and method for program vulnerability testing of unmanned aerial vehicles

Abstract

The invention discloses a state monitoring device and method for program vulnerability testing of an unmanned aerial vehicle. Using the present invention can detect the operation state of the control logic of the drone in real time, provide more dimensional feedback information for the test tool, and expand the depth of the network information security test. The device of the present invention includes a communication monitor and a logic monitor; the communication monitor is used to detect whether the communication service of the DUT is normal; the logic monitor collects the ESC and steering gear signals sent by the core module of the DUT, and utilizes the DUT dynamics and kinematics numerical model Calculate its attitude angle, acceleration, angular velocity and other information, and compare the real-time calculation results of the numerical model with the historical calculation results to identify abnormalities in the flight control logic in time and realize the state monitoring of the DUT control logic.

Description

technical field [0001] The invention relates to the technical field of computer software vulnerability mining, in particular to a state monitoring device and method for program vulnerability testing of drones. Background technique [0002] UAV is a new type of equipment that integrates computer technology, communication technology, sensor technology and automatic control theory. It is widely used in disaster relief, urban management, power inspection, agriculture, forestry and plant protection and other industries. UAVs have strong mobility. Once it is hijacked by hackers, it is likely to cause serious consequences such as hitting people, breaking into restricted areas, interfering with air routes, and even leaking information. Program vulnerability testing on UAVs can dig out software vulnerabilities, which helps manufacturers to patch vulnerabilities and upgrade firmware in a timely manner, thereby reducing the network information security risk of UAVs. [0003] Since the...

Problems solved by technology

The advantage of this type of method is that it has a high degree of generalization and is easy to operate stably. However, due to the coupling between the communication component and the flight control component of the UAV, there may be situations where the flight control component is abnormal but the communication component still responds normally (mostly in Hacker hijacking, stall crash and other scenarios), at this time, this kind of method cannot detect the abnormal state generated by the deeper control logic, resulting in missed detection
