Abstract

Embodiments include methods performed by vehicle-to-everything (V2X) system for protecting proprietary data within misbehavior reports. Various embodiments may include detecting misbehavior conditions based on received sensor data, determining whether the received sensor data that supports a conclusion that a misbehavior condition has occurred is or includes proprietary information, and encrypting the sensor data that supports the conclusion that the misbehavior condition has occurred in response to determining that the received sensor data is or includes the proprietary information. Various embodiments may further include generating a misbehavior report including the received sensor data that supports the conclusion that the misbehavior condition has occurred in response to determining that the misbehavior condition has occurred, in which the received sensor data included in the misbehavior report is encrypted in response to determining that the received sensor data is or includes proprietary information, and transmitting the generated misbehavior report to a misbehavior managing authority.

First claim

What is claimed is:

1. A method of protecting proprietary information included in vehicle-to-everything (V2X) system messages, comprising: encrypting proprietary information included in sensor data obtained from one or more sensors indicating that a misbehavior condition has occurred; determining whether transmitting a misbehavior report including the encrypted proprietary information to a misbehavior managing authority is inappropriate; in response to determining that transmitting the misbehavior report including the encrypted proprietary information to the misbehavior managing authority is inappropriate: generating a first misbehavior report to include a field indicating that the sensor data indicating that the misbehavior condition has occurred is or will be transmitted separately; uploading the encrypted proprietary information included in the sensor data over a secure communication link; and transmitting the first misbehavior report to the misbehavior managing authority.

2. The method of claim 1 , further comprising; determining whether the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred includes the proprietary information, wherein encrypting the proprietary information included in the sensor data comprises encrypting portions of the sensor data that include the proprietary information in response to determining that the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred includes the proprietary information.

3. The method of claim 1 , further comprising: identifying each entity that owns an instance of the proprietary information included in the sensor data indicating that the misbehavior condition has occurred, wherein encrypting the proprietary information included in the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred comprises encrypting instances of the proprietary information included in the sensor data using a public key associated with the entity that owns respective instances of the proprietary information.

4. The method of claim 1 , further comprising generating a second misbehavior report to include the encrypted proprietary information in response to determining that transmitting the misbehavior report including the encrypted proprietary information to the misbehavior managing authority is appropriate.

5. The method of claim 1 , further comprising generating a second misbehavior report identifying the misbehavior condition and including information regarding the encrypted proprietary information, wherein determining whether transmitting the misbehavior report to the misbehavior managing authority is inappropriate comprises determining that the second misbehavior report is inappropriate to transmit in response to determining that the encrypted proprietary information that supports a conclusion that the misbehavior condition has occurred is too large to transmit in the second misbehavior report.

6. The method of claim 1 , further comprising generating a second misbehavior report identifying the misbehavior condition and including information regarding the encrypted proprietary information, wherein determining whether transmitting the misbehavior report to the misbehavior managing authority is inappropriate comprises determining that the second misbehavior report is inappropriate to transmit in response to determining that the encrypted proprietary information that supports a conclusion that the misbehavior condition has occurred should not be transmitted over an unsecure wireless communication link.

7. The method of claim 1 , wherein the field that indicates that the sensor data supporting a conclusion that the misbehavior condition has occurred is transmitted separately includes information identifying a location to which the encrypted proprietary information was uploaded over the secure communication link.

8. A vehicle-to-everything (V2X) processing device, comprising: a processor configured with processor-executable instructions to: encrypt proprietary information included in sensor data obtained from one or more sensors indicating that a misbehavior condition has occurred; determine whether transmitting a misbehavior report including the encrypted proprietary information to the misbehavior managing authority is inappropriate; in response to determining that transmitting the misbehavior report including the encrypted proprietary information to the misbehavior managing authority is inappropriate: generate a first misbehavior report to include a field that indicates that the sensor data indicating that the misbehavior condition has occurred is or will be transmitted separately; upload the encrypted proprietary information included in the sensor data over a secure communication link; and transmit the first misbehavior report to the misbehavior managing authority.

9. The V2X processing device of claim 8 , wherein the processor is further configured with processor-executable instructions to: determine whether the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred includes the proprietary information; and encrypt the proprietary information included in the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred by encrypting portions of the sensor data that include the proprietary information in response to determining that the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred includes the proprietary information.

10. The V2X processing device of claim 8 , wherein the processor is further configured with processor-executable instructions to: identify each entity that owns an instance of the proprietary information included in the sensor data indicating that the misbehavior condition has occurred; and encrypt the proprietary information included in the sensor data obtained from the one or more sensors indicating that the misbehavior condition has occurred by separately encrypting each instance of the proprietary information included in the sensor data using a public key associated with the entity that owns each respective instance of the proprietary information.

11. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to generate a second misbehavior report to include the encrypted proprietary information in response to determining that transmitting the misbehavior report including the encrypted proprietary information to the misbehavior managing authority is appropriate.

12. The V2X processing device of claim 8 , wherein the processor is further configured with processor-executable instructions to: generate a second misbehavior report configured to provide the encrypted proprietary information to the misbehavior managing authority; and determine that the second misbehavior report is inappropriate to transmit in response to determining that the encrypted proprietary information that supports a conclusion that the misbehavior condition has occurred is too large to transmit in a misbehavior report.

13. The V2X processing device of claim 8 , wherein the processor is further configured with processor-executable instructions to: generate a second misbehavior report configured to provide the encrypted proprietary information to the misbehavior managing authority; and determine that the second misbehavior report is inappropriate to transmit in response to determining that the encrypted proprietary information that supports a conclusion that the misbehavior condition has occurred should not be tr
