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.

Notifying local vehicle-to-everything misbehavior to receive-side local misbehavior detection system

A method of wireless communication at a first V2X device is described herein. The method includes obtaining a message including a MAC header, an L1 source ID, and an L1 destination ID. The method includes decoding the MAC header to produce an L2 source ID associated with the message based on at least one of (1) the L1 destination ID of the message matching a first number of bits of an L2 source ID of the first V2X device or (2) the L1 source ID of the message matching a second number of bits of the L2 source ID of the first V2X device. The method includes outputting an indication of a MAC cloning attack based on the L2 source ID of the message matching the L2 source ID of the first V2X device.

MAC address cloning attack detection for V2X devices

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.

Managing processing of a basic safety message

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.

Misbehavior detection service for sharing connected and sensed objects

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.

Reputation score assignment for vehicle-based communications

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.

Cross-type misbehavior detection in a vehicle-to-everything (V2X) message

Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a process may include determining a potential position overlap between a first vehicle and a second vehicle and determining a characteristic of at least one of the first vehicle or the second vehicle based on information from a vehicle-based message. The process may include determining whether the potential position overlap is an actual position overlap between the first vehicle and the second vehicle based on the characteristic.

Detection of position overlap (PO) between objects

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.

Error correction system for a misbehavior detection system

Methods, systems, and devices for wireless communications are described. A communication device may detect vehicle-to-everything (VX) fuzzing attacks. The communication device may receive a set of packets. Each packet of the set of packets includes a set of information element (IE) fields. The communication device determine a change to one or more IE fields of the set of IE fields and associated with at least a subset of packets of the set of packets based on comparing a respective value associated with each of the one or more IE fields to a respective default value associated with each of the one or more IE fields. As a result, the communication device may transmit a report indicating a plurality of fuzzing attacks at the communication device.

Techniques for misbehavior detection in wireless communications systems

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.
