摘要： A method for managing a plurality of imaging devices in a vehicle includes determining that a change of data security mode is indicated for frames of image data transmitted over a first data communication link, determining whether a sensor management system has sufficient processing capacity to support the change of data security mode, increasing the processing capacity of the sensor management system by modifying data security settings for at least one other data communication link when the processing capacity of the sensor management system is insufficient to support the change of data security mode, and initiating the change of data security mode when the sensor management system has sufficient processing capacity to support the change of data security mode. The change of data security mode may include a change from an application-based to a link-based data security mode or a change from the link-based to the application-based data security mode.

摘要： Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes determining, at the first network device, an estimated location of a second network device. The process may further include comparing, at the first network device, the estimated location with an expected location for the second network device. The process may include determining, at the first network device, whether the second network device is a misbehaving device based on the comparing. The process may further include generating, at the first network device, a report based on the determining of whether the second device is a misbehaving device.

摘要： Various embodiments include methods and systems for vehicle-to-everything (V2X) system of a vehicle for managing processing of a basic safety message (BSM). Various embodiments may include calculating a relevancy value of a received BSM prior to conducting security processing of the BSM, determining whether the relevancy value of the BSM meets a relevancy threshold, and stopping processing of the BSM in response to determining that the relevancy value of the BSM does not meet the relevancy threshold.

摘要： Systems and techniques are described for assigning a reputation score for vehicle-to-everything (V2X) communications. For example, a process may include receiving, at a receiving device (e.g., a vehicle, network entity, etc.), vehicle-based messages from a transmitting device (e.g., a vehicle, network-equipped infrastructure, etc.). Each of the vehicle-based messages includes information associated with the transmitting device. The process may include determining, at the receiving device, a reputation score for the transmitting device based on at least a portion of the information associated with the transmitting device from each vehicle-based message of the plurality of vehicle-based messages.

摘要： Methods, apparatuses, systems, and non-transitory computer-readable media are disclosed for V2X misbehavior detection at a device. A disclosed method comprises performing context detection to generate a determined context for the device. The method further comprises performing a plurality of plausibility checks to generate a plurality of plausibility outputs. At least one plausibility check of the plurality of plausibility checks is performed based on inputs including (1) a reported value obtained from a received V2X message and (2) the determined context for the device. The method further comprises weighing and combining the plurality of plausibility outputs, by applying at least one set of weights based on the determined context for the device, to generate at least one combined, weighted plausibility indicator value. The method further comprises performing at least one misbehavior detection based on the at least one combined, weighted plausibility indicator value, to generate at least one misbehavior detection result.

摘要： Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes detecting an object based on sensor data from at least one sensor of the network device. The process further includes receiving, by the network device, a vehicle-based message comprising message data related to the object. The process further includes comparing, by the network device, the sensor data and the message data and detecting, by the network device, malicious behavior based on the comparing.

摘要： A first UE may receive a V2X message from a second UE. The V2X message may be a suspicious message. The V2X message may include a plurality of values. Each value in the plurality of values may correspond to a respective field in a plurality of fields. The first UE may identify a health score associated with the V2X message. The first UE may adjust at least one value in the plurality of values if the health score is greater than a threshold. Accordingly, a health level of a suspicious V2X message may be analyzed quantitatively. A suspicious V2X message with a sufficiently low health level may be suppressed. Moreover, a correctable field value in a suspicious V2X message may be corrected based on a computed, measured, or prestored value.

摘要： Systems and techniques are described for validating object detection. For example, an apparatus can obtain sensor data corresponding to a field-of-view of a vehicle. The apparatus can receive a message from a wireless device. The message includes an indication of at least one object in the field-of-view of the vehicle and a reported location of the at least one object. The apparatus can further determine, based on the sensor data and the message from the wireless device, whether the wireless device has misreported the at least one object.

摘要： Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.
