Security certificate management and misbehavior vehicle reporting in vehicle-to-everything (V2X) communication

A method of operating a device at an edge of a vehicular communication network, the method comprising:

• monitoring communication messages within a coverage area of the device through the device;
• identifying vehicles currently within the coverage area based on the monitoring;
• generating vehicle security data to be distributed to the identified vehicles based at least in part on a context related to the vehicles, the identified vehicles, the monitored messages, and information from a server in the vehicular communication network, wherein the vehicle security data includes a misbehavior report (MBR), the MBR includes identities of one or more misbehaving vehicles;
• generating the MBR to include an identity of a misbehaving vehicle when a report on misbehavior of the misbehaving vehicle has been received from another vehicle, and the misbehaving vehicle is within the coverage area of the device or will be within the coverage area based on a prediction according to a trajectory of the misbehaving vehicle;
• announcing, on a control channel communicatively coupling the device and the vehicles, that the vehicle security data is available and a service channel to receive the vehicle security data;
• and
• distributing the vehicle security data to the vehicles via the service channel.

An apparatus disposed at an edge of a vehicular communication network, the apparatus comprising:

• network communication circuitry;
• memory circuitry;
• and
• processor circuitry connected to the memory circuitry and the network communication circuitry, the processor circuitry to:
• monitor communication messages within a coverage area of the apparatus through the network communication circuitry;
• identify vehicles currently within the coverage area based on the monitored communication messages;
• generate vehicle security data to be distributed to the identified vehicles based at least in part on a context related to the vehicles, the identified vehicles, the monitored messages, and information from a server in the vehicular communication network, wherein the vehicle security data includes a misbehavior report (MBR), the MBR includes identities of one or more misbehaving vehicles, and the method includes, and the MBR is to include an identity of a misbehaving vehicle when a report on misbehavior of the misbehaving vehicle has been received from another vehicle, and the misbehaving vehicle is within the coverage area or is predicted to be within the coverage area based on a trajectory of the misbehaving vehicle;
• and
• cause the network communication circuitry to:
• announce, via a control channel, that the vehicle security data is available and a service channel over which to receive the vehicle security data, and
• distribute, via the service channel, the vehicle security data to the vehicles.
