Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Various embodiments include methods and systems for performing misbehavior detection in a vehicle-to-everything (V2X) message. Various embodiments may include a V2X system of a vehicle comparing a first field in a first V2X message of a first V2X message type to a second field in a second V2X message of a second V2X message type, wherein the second V2X message type is different from the first V2X message type, identifying misbehavior in either the first V2X message or the second V2X message based on the comparison, and taking an action in response to identifying misbehavior in the first V2X message or the second V2X message.

Abstract: Embodiment methods implemented in vehicle-to-everything (V2X) systems may include detecting multiple indications of V2X misbehavior by multiple misbehavior detection mechanisms, aggregating misbehavior indications output from the misbehavior detection mechanisms, determining whether a reportable or actionable misbehavior condition exists based on aggregated misbehavior indications, and acting on a determined misbehavior condition. Aggregating misbehavior indications may include determining whether any of the misbehavior detection mechanisms outputs a misbehavior indication, determining whether any one of a select subset of the one or more misbehavior detection mechanisms outputs a misbehavior indication, aggregating misbehavior indications output from multiple misbehavior detection mechanisms and comparing the number to a threshold, applying a weight to misbehavior indication outputs and aggregating the weighted outputs, or determining a number of events classified as an attack or misbehavior indications output by each of a plurality of misbehavior detection mechanisms within a window of time or set number of events.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a misbehavior condition in a local vehicle-to-everything (V2X) information source. The UE may receive an incoming V2X message. The UE may generate a misbehavior decision for the incoming V2X message based at least in part on the misbehavior condition in the local V2X information source. Numerous other aspects are described.

Abstract: Embodiments include methods performed by vehicle-to-everything (V2X) system for evaluating V2X information. Some embodiments may include receiving from a V2X entity a length value and width value of the V2X entity, determining whether the received length value and width value are reliable, and performing a position overlap check using the received length value and width value in response to determining that the received length value and width value are reliable.

Abstract: In various embodiments, a vehicle-to-everything (V2X) processing device may receive V2X messages from intelligent transportation system (ITS) stations, analyze information in received V2X messages to detect misbehavior conditions, and add a station identifier associated with a V2X message received from an ITS station to a local blocking list in response to detecting a misbehavior condition in the V2X message received from the ITS station. In some embodiments, the V2X processing device may transmit a misbehavior report to a management entity in response to detecting the misbehavior condition in the V2X message.

Abstract: 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.
