Abstract

Embodiments include methods performed by a vehicle-to-everything (V2X) system for protecting proprietary data within misbehavior reports. The method includes receiving a misbehavior report from a V2X system participant, obtaining sensor data from the received misbehavior report indicating that a misbehavior condition has occurred, determining whether the sensor data indicating that a misbehavior condition has occurred includes encrypted proprietary information. In response to determining that the sensor data includes encrypted proprietary information, the V2X system identifies an entity that owns the encrypted proprietary information, transmits the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information, and receives a confirmation report from the entity that owns the encrypted proprietary information indicating whether the misbehavior report is accurate.

First claim

What is claimed is:

1 . A method of protecting proprietary information in vehicle-to-everything (V2X) system messages, comprising:
receiving a misbehavior report from a V2X system participant; obtaining sensor data from the received misbehavior report indicating that a misbehavior condition has occurred; determining whether the sensor data indicating that a misbehavior condition has occurred includes encrypted proprietary information; and in response to determining that the sensor data includes encrypted proprietary information:
identifying an entity that owns the encrypted proprietary information;
transmitting the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information; and
receiving a confirmation report from the entity that owns the encrypted proprietary information indicating whether the misbehavior report is accurate.

2 . The method of claim 1 , wherein:
identifying the entity that owns the encrypted proprietary information comprises identifying each entity that owns each instance of encrypted proprietary information included in the misbehavior report; transmitting the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information comprises transmitting the misbehavior report including the encrypted proprietary information to each entity that owns an instance of encrypted proprietary included in the misbehavior report; and receiving a confirmation report from the entity that owns the encrypted proprietary information indicating whether the sensor data is accurate comprises receiving a confirmation report from each entity that owns an instance of encrypted proprietary information indicating whether the misbehavior report is supported by that entity's encrypted proprietary information.

3 . The method of claim 1 , further comprising:
obtaining, from the received confirmation report, information or instructions for responding to a misbehavior condition identified in the misbehavior report; and transmitting the information or instructions for responding to a misbehavior condition to the V2X system participant.

4 . The method of claim 1 , wherein determining whether the sensor data indicating that a misbehavior condition has occurred includes encrypted proprietary information comprises identifying that the sensor data includes proprietary information based on a configuration setting.

5 . The method of claim 1 , wherein receiving a confirmation report from the entity that owns the encrypted proprietary information comprises receiving, over a separate secure communication link, information regarding the sensor data sufficient to confirm whether the misbehavior condition occurred.

6 . The method of claim 5 , further comprising:
evaluating the misbehavior report based on the confirmation report to determine whether the misbehavior report is confirmed.

7 . The method of claim 1 , wherein transmitting the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information comprises:
storing the encrypted proprietary information at a location in a memory associated with or controlled by the owner of the sensor data; and transmitting the owner of the sensor data the location in the memory containing the encrypted proprietary information.

8 . A computing device, comprising:
a processor configured with processor-executable instructions to:
receive a misbehavior report identifying a misbehavior condition has occurred from a V2X system participant;
obtain sensor data from the received misbehavior report indicating that the misbehavior condition has occurred;
determine whether the sensor data indicating that the misbehavior condition has occurred includes encrypted proprietary information; and
in response to determining that the sensor data includes encrypted proprietary information:
identify an entity that owns the encrypted proprietary information;
transmit the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information; and
receive a confirmation report from the entity that owns the encrypted proprietary information indicating whether the misbehavior report is accurate.

9 . The computing device of claim 8 , wherein the processor is further configured with processor-executable instructions to:
identify each entity that owns each instance of encrypted proprietary information included in the misbehavior report; transmit the misbehavior report including the encrypted proprietary information to each entity that owns an instance of encrypted proprietary information included in the misbehavior report; and receive a confirmation report from each entity that owns an instance of encrypted proprietary information indicating whether the misbehavior report is supported by that entity's encrypted proprietary information.

10 . The computing device of claim 8 , wherein the processor is further configured with processor-executable instructions to:
obtain, from the received confirmation report, information or instructions for responding to a misbehavior condition identified in the misbehavior report; and transmit the information or instructions for responding to a misbehavior condition to the V2X system participant.

11 . The computing device of claim 8 , wherein the processor is further configured with processor-executable instructions to determine whether the sensor data indicating that a misbehavior condition has occurred by identifying that the sensor data includes proprietary information based on a configuration setting.

12 . The computing device of claim 8 , wherein the processor is further configured with processor-executable instructions to receive the confirmation report from the entity that owns the encrypted proprietary information over a separate secure communication link information regarding the sensor data that is sufficient to confirm whether the misbehavior condition occurred.

13 . The computing device of claim 8 , wherein the processor is further configured with processor-executable instructions to evaluate the misbehavior report based on the confirmation report to determine whether the misbehavior report is confirmed.

14 . The computing device of claim 10 , wherein the processor is further configured with processor-executable instructions to transmit the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information by:
storing the encrypted proprietary information at a location in a memory associated with or controlled by the owner of the sensor data; and
transmitting the owner of the sensor data the location in the memory containing the encrypted proprietary information.

15 . A non-transitory processor-readable medium having stored thereon processor-executable instructions configured to cause a processor a of a computing device to perform operations comprising:
receiving a misbehavior report from a V2X system participant; obtaining sensor data from the received misbehavior report indicating that a misbehavior condition has occurred; determining whether the sensor data indicating that a misbehavior condition has occurred includes encrypted proprietary information; and identifying an entity that owns the encrypted proprietary information in response to determining that the sensor data includes encrypted proprietary information; transmitting the misbehavior report including the encrypted proprietary information to th
