[0002] Currently, in the field of intelligent driving, there is a potential for side-channel attacks, particularly from acoustic, optical, and electromagnetic sources. The widespread application of multimodal autonomous driving technologies creates a need for assessing vehicles' defense capabilities against these attacks, i.e., a requirement for effective side-channel attack security testing. If side-channel attack defense capabilities are not assessed before mass production, attacks on vehicles on the road will directly affect steering, speed changes, and other aspects, directly impacting the safety of those involved in traffic.

[0018] If all the surface acoustic wave sensors in the current test vehicle have been traversed, it indicates that all the surface acoustic wave sensors in the current test vehicle have completed the safety test.

[0019] If all the surface acoustic wave sensors in the current test vehicle have not been traversed, then the step of performing side-channel interference testing on all the surface acoustic wave sensors in the current test vehicle using test acoustic waves of different frequency bands continues.

[0020] Optionally, the surface acoustic wave sensor includes:

[0023] If the monitoring results indicate that the current test vehicle can drive according to the preset driving mode, then the current test vehicle is determined to have passed the side channel security test.

[0024] If the monitoring results indicate that the current test vehicle is unable to drive according to the preset driving mode, then the current test vehicle is determined to have failed the side-channel security test.

[0025] Secondly, the present invention discloses a vehicle safety testing device, comprising:

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Currently, there is a need to effectively address the security testing of vehicle side-channel attacks. If the side-channel attack defense capability is not evaluated before vehicle mass production, side-channel attacks on vehicles on the road will directly affect the steering, speed change, etc., directly impacting the personal safety of traffic personnel. Therefore, evaluating the side-channel attack defense capability of vehicles before mass production is extremely important. To this end, the present invention provides a vehicle safety testing scheme that can solve the security problems caused by side-channel attack risks in existing intelligent driving systems.

[0041] This invention discloses a vehicle safety testing method, see [link to relevant documentation]. Figure 1 As shown, the method includes:

[0042] Step S11: During the vehicle road test, side-channel interference tests are conducted on all surface acoustic wave sensors in the current test vehicle using test sound waves of different frequency bands.

[0043] In this embodiment, the safety testing of automotive sensors is based on the principle of acoustic resonance. During vehicle road testing, test sound waves of different frequencies emitted from inside or outside the vehicle are used to conduct safety tests on all surface acoustic wave (SAW) sensors in the vehicle. In other words, by using test sound waves of different frequencies, acoustic resonance is achieved, thereby interfering with the normal operation of the automotive sensors and thus achieving the purpose of evaluating their safety performance. For example, the principle of acoustic resonance can be used to interfere with vehicle acceleration commands, tire pressure warnings, vehicle steering, and power delivery. It should be noted that the entire testing process must be conducted in a dedicated vehicle testing area to prevent any accidents from occurring during the testing process.

[0044] In this embodiment, the surface acoustic wave (SAW) sensor in the test vehicle is an active sensor, specifically including a resonant accelerometer, a SAW pressure sensor, a steering angle sensor, an ultrasonic flow sensor, an ultrasonic level sensor, a SAW temperature and humidity sensor, a vehicle tilt angle sensor, and an ultrasonic sensor. It should be noted that the resonant accelerometer is used to detect vibrations during vehicle acceleration and deceleration, and the SAW pressure sensor is used to detect tire pressure and brake master cylinder pressure. Pressure sensors are categorized into capacitive sensors, piezoresistive sensors, differential transformer sensors, and SAW sensors. Tire pressure is used in electronic stability control systems, brake sensors, side airbags, engine control related to increasingly stringent emission standards, atmospheric pressure, and exhaust gas recirculation pressure. A vibrating gyroscope, also known as a steering angle sensor, is used to detect changes in the vehicle's steering angle. Several types exist, including vibrating and rotor types, with vibrating gyroscopes being the most widely used. Vibrating gyroscopes utilize the Coriolis effect generated when a vibrating mass of monocrystalline or polycrystalline silicon is rotated by a base to sense angular velocity. Ultrasonic flow sensors are used to detect the amount of air intake and fuel injection in an engine, thereby controlling the air-fuel ratio near its optimal value. Furthermore, ultrasonic flow sensors are widely used in exhaust gas recirculation, anti-slip drive systems, anti-lock braking systems, and electronically controlled suspensions. Ultrasonic level sensors are used to detect the levels of fuel, coolant, brake fluid, and battery fluid. Types of level sensors include float type, pressure type, ultrasonic type, capacitive type, and magnetic type. Surface acoustic wave (SAW) temperature and humidity sensors are used to detect engine intake air temperature, engine oil temperature, and transmission oil temperature. Vehicle tilt angle sensors detect the vehicle's tilt angle during cornering or driving and transmit this information to the ECU (Electronic Control Unit). When the vehicle tilt angle exceeds a preset angle, such as 60°, the ECU immediately disconnects the fuel supply circuit. Vehicle tilt angle sensors can be classified into three types based on their working principle: solid pendulum type, liquid pendulum type, and gas pendulum type. Ultrasonic sensors are used for parking distance control in APA (Auto Parking Assist), which automatically parks the vehicle by controlling its acceleration, deceleration, and steering angle.

[0045] In one specific implementation, the generation of test sound waves in different frequency bands may include: generating test sound waves in different frequency bands by controlling the operation of an executable test program; the executable test program is a program pre-installed in the vehicle-mounted speaker device or non-vehicle-mounted speaker device on the current measurement vehicle for running sound wave signals within a preset frequency band range. For example, in a car smart speaker, an executable test program can be installed with developer privileges, or a high-power networked speaker can be placed within the receiving range of the current test vehicle, or a high-power networked speaker with a pre-installed executable test program can be directly placed in the current test vehicle. This executable test program can be used to run sound wave signals from 100Hz to 10MHz. If the vehicle testers are unsure of the vehicle's sensor parameters, they can choose to traverse the sound wave interference signal. That is, by traversing the test sound waves, different frequency bands of test sound waves are generated sequentially according to a preset traversal interval. The side-channel interference test of each surface acoustic wave sensor in the current test vehicle is then performed using the test sound waves of different frequency bands. For example, the traversal interval can be set to 1000Hz. If the resonant frequencies of all sensors are known, the corresponding sound wave test area can be directly set. That is, different frequency bands of test sound waves are generated according to the preset sound wave test area, and the side-channel interference test of each surface acoustic wave sensor in the current test vehicle is then performed using the test sound waves of different frequency bands. This can reduce the test time. It should be noted that the executable test program can be remotely started and stopped via a host computer. That is, the host computer can remotely control the operation of the executable test program to generate test sound waves of different frequency bands, and each test frequency is an interference signal message with the same carrier.

[0046] In another specific implementation, the generation of test sound waves in different frequency bands may include: adjusting the vehicle's in-vehicle broadcasting system to the test broadcasting frequency band to generate test sound waves in different frequency bands. For example, adjusting the in-vehicle radio to the test broadcasting frequency band. The broadcast carrier frequency band is 100Hz to 10MHz. Similarly, if the vehicle testing personnel are unsure of the vehicle's sensor parameters, they can choose to traverse the sound wave interference signals; if they know the resonant frequencies of all sensors, they can directly set the corresponding sound wave test area, thereby reducing the testing time.

[0047] In this embodiment, after performing side-channel interference testing on all surface acoustic wave (SAW) sensors in the current test vehicle using test sound waves of different frequency bands during vehicle road testing, the process may further include: checking the current test progress to determine whether all SAW sensors in the current test vehicle have been traversed; if all SAW sensors in the current test vehicle have been traversed, it indicates that all SAW sensors in the current test vehicle have completed the safety test; if all SAW sensors in the current test vehicle have not been traversed, the step of performing side-channel interference testing on all SAW sensors in the current test vehicle using test sound waves of different frequency bands continues. It is understood that remotely checking the test progress of the current test vehicle is used to determine whether all SAW sensors in the current test vehicle have been tested. If all SAW sensors in the current test vehicle have not been tested, the step of performing side-channel interference testing on all SAW sensors in the current test vehicle using test sound waves of different frequency bands continues. If all SAW sensors in the current test vehicle have been tested, it indicates that the entire automotive sensor safety test based on the acoustic resonance principle is complete.

[0048] Step S12: During the side-channel interference test, monitor whether the current test vehicle is driving according to the preset driving mode and obtain the corresponding monitoring results.

[0049] It is understandable that during the side-channel interference test, the safety attribute assessment of the current test vehicle is determined by monitoring whether the current test vehicle is driving according to the preset driving mode.

[0050] Step S13: Determine whether the current test vehicle has passed the side-channel security test based on the monitoring results.

[0051] Understandably, if the monitoring results indicate that the current test vehicle can drive according to the preset driving mode, then the current test vehicle is deemed to have passed the side-channel safety test; if the monitoring results indicate that the current test vehicle cannot drive according to the preset driving mode, then the current test vehicle is deemed to have failed the side-channel safety test. In other words, if the vehicle experiences a loss of control during the side-channel interference test, such as abnormal phenomena like abnormal speed changes, abnormal steering, abnormal tire pressure warnings, or abnormal instrument panel warnings, then the current test vehicle is deemed to have failed the side-channel safety test, indicating that the vehicle's safety attributes assessment is inadequate. Furthermore, after the current test vehicle exhibits abnormal phenomena, the current test is remotely paused, and the test driver and tester record the abnormal situation and the corresponding acoustic resonance frequency band from the monitoring results. The abnormal frequency is displayed on the remote control console, and then the surface acoustic wave sensor with a safety risk is identified based on the abnormal situation and the acoustic resonance frequency band. That is, after the test is completed, the location of the problematic sensor can be determined through the abnormal phenomena and frequencies, and the dashcam and operator monitoring videos are collected and stored for later exclusion of human error. After the entire automotive sensor safety test based on the acoustic resonance principle is completed, the surface acoustic wave (SAW) sensors with potential safety risks are reviewed, and a corresponding review report is output. If the vehicle operates according to its settings during all resonance tests for all SAW sensors in the vehicle, then the vehicle passes the acoustic side-channel safety test.

[0052] For example, see Figure 2 As shown, test sound waves of different frequencies are emitted via smart speakers or in-vehicle broadcasting to conduct side-channel interference tests on all active surface acoustic wave sensors on the test vehicle, such as surface acoustic wave pressure sensors, vibrating gyroscopes (i.e., steering angle sensors), ultrasonic flow sensors, ultrasonic level sensors, surface acoustic wave temperature and humidity sensors, vehicle tilt angle sensors, and ultrasonic sensors. During the test, the success of the test is determined by observing any abnormalities in the vehicle. If an abnormality is found, the corresponding sensor's function has a safety hazard, requiring timely enhancement of safety features or replacement of the technical solution. The safety test points for automotive sensors based on the principle of acoustic wave resonance are shown in Table 1.

[0053] Table 1

[0054]

[0055]

[0056] For example, see the entire safety test for automotive sensors based on the principle of acoustic resonance. Figure 3As shown, if the test program is pre-installed on the current test vehicle, it can be installed on the in-vehicle smart speaker with developer privileges. If the test program is not pre-installed on the current test vehicle, but test sound waves of different frequency bands are generated through an external device, a high-power networked speaker with the pre-installed test program can be directly placed on the current test vehicle. If test sound waves of different frequency bands are not generated through an external device, they can be generated by tuning the car radio to the test broadcast frequency band. For example, tuning the car radio to the test broadcast frequency band. The broadcast carrier frequency band is 100Hz to 10MHz, and the test program can be used to run sound wave signals of 100Hz to 10MHz. Furthermore, some in-vehicle speaker functions are integrated into the smart cockpit domain control. Assuming the vehicle tester is unfamiliar with the vehicle's sensor parameters and selects to traverse acoustic interference signals with an interval of 1000, the test program will traverse the acoustic resonance signals of all surface acoustic wave (SAW) active sensors to perform side-channel interference testing. The test vehicle then travels at a constant speed along the test track while the test program runs or a test signal is broadcast to the test optical frequency band. During the test, the system monitors the vehicle's movement in real time for any abnormal phenomena. If the test vehicle deviates from its course (i.e., abnormal steering) during the test, the test is remotely paused, and the test driver and tester record the abnormal behavior and the test acoustic resonance frequency band displayed on the remote control console. After the test, the location of the problematic sensor can be determined by the abnormal phenomena and frequencies. Simultaneously, dashcam footage and operator monitoring video are collected and stored for later investigation to rule out human error. If the test vehicle, traveling at a constant speed, does not experience any abnormalities during the test, it indicates that the current frequency interference acoustic wave test is complete. The test progress is then remotely monitored to determine if all vehicle sensors on the current test vehicle have been tested. If not, the relevant tests continue. If the testing is complete, the entire automotive sensor safety test based on the acoustic resonance principle is finished. Subsequent checks are performed against sensors with safety risks according to Table 1, and relevant reports are output. This effectively addresses the side-channel ambiguity safety testing requirements for all acoustic-related sensors in vehicles. Furthermore, by simulating risk scenarios of real vehicle road operation, the safety test results are made more convincing.

[0057] As can be seen from the above, in this embodiment of the application, the side-channel interference test is performed on all surface acoustic wave sensors in the current test vehicle using test sound waves of different frequency bands based on the principle of acoustic resonance. During the side-channel interference test, the driving status of the current test vehicle is monitored, and the test vehicle passes the side-channel security test based on the monitoring results. This can solve the problem of assessing the security defense capability against acoustic side-channel attacks before mass production of vehicles, and can also solve the security problems caused by side-channel attack risks in existing intelligent driving systems.

[0062] As can be seen from the above, in this embodiment of the invention, based on the principle of acoustic resonance, test acoustic waves of different frequency bands are used to conduct side-channel interference tests on all surface acoustic wave sensors in the current test vehicle. During the side-channel interference test, the driving status of the current test vehicle is monitored, and the test vehicle passes the side-channel security test based on the monitoring results.

The test judgment module is used to determine whether the current test vehicle has passed the side-channel security test based on the monitoring results; The interference testing module includes: The first interference test unit is used to generate test sound waves of different frequency bands sequentially according to a preset traversal interval by means of test sound wave traversal, and to use the test sound waves of different frequency bands sequentially to perform side channel interference tests on each surface acoustic wave sensor in the current test vehicle. Alternatively, the second interference test unit is used to generate test sound waves of different frequency bands according to a pre-set sound wave test area, and sequentially use the test sound waves of different frequency bands to perform side channel interference tests on each surface acoustic wave sensor in the current test vehicle. Also includes: The judgment module is used to check the current test progress to determine whether all the surface acoustic wave sensors in the current test vehicle have been traversed. The first processing module is configured to indicate that all surface acoustic wave sensors in the current test vehicle have completed the safety test if all of the surface acoustic wave sensors in the current test vehicle have been traversed. The second processing module is used to continue executing the step of performing side-channel interference testing on all surface acoustic wave sensors in the current test vehicle using test sound waves of different frequency bands if all the surface acoustic wave sensors in the current test vehicle have not been traversed.
