Assignee: INTEL CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 6:
7. A system, comprising:
an in-vehicle-network (IVN);
a plurality of electronic control units (ECUs) communicatively coupled via the IVN;
an intrusion detection system (IDS) circuitry coupled to the IVN, the IDS circuitry to identify an attack on the IVN;
a vehicle-to-vehicle (V2X) communication circuitry comprising a processor and memory, the memory comprising instructions that when executed by the processor cause the processor to:
receive from the IDS circuitry, a notification of the attack on the IVN, the notification to indicate an ECU is under attack, the ECU to provide information representing a physical characteristic of a vehicle;
generate a message comprising an information element with a request for the physical characteristic of the vehicle provided by the ECU;
broadcast the information element to a connected vehicle;
receive a response from the connected vehicle, the response comprising an indication of the physical characteristic; and
initiate recovery from the attack based in part on the response using the indication of the physical characteristic to estimate the information for the ECU.
