V2X Misbehavior Report Encryption for Proprietary Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-everything (V2X) communication systems, there is a challenge in protecting proprietary sensor data that indicates a misbehavior condition, as transmitting such data over public networks can compromise confidentiality, and existing methods do not adequately ensure the confidentiality and integrity of this information during misbehavior reporting.
Innovation Solution
The solution involves encrypting proprietary information in sensor data using public keys associated with the respective owners, allowing for secure transmission of misbehavior reports while maintaining confidentiality, and ensuring that only the owners can decrypt and verify the accuracy of the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary sensor data is transmitted over public networks for misbehavior reporting, then the misbehavior reporting function is enabled, but the confidentiality of proprietary information is compromised
Solution Approach 1:
The patent introduces an encryption intermediary mechanism where proprietary sensor data is encrypted using public keys before transmission. The encryption module acts as an intermediary between the data source and the misbehavior managing authority, transforming the data into a protected form that maintains confidentiality while enabling the reporting function. Only the intended recipient with the corresponding private key can decrypt and access the original proprietary information.
2Loss of information
If proprietary information is encrypted using public keys, then confidentiality is protected, but the complexity of the reporting system increases
Solution Approach 1:
The patent applies preliminary action by pre-distributing public keys to the misbehavior managing authority before the actual misbehavior reporting occurs. This advance preparation of cryptographic materials simplifies the reporting process itself, as the encryption and decryption mechanisms are already in place and configured, reducing the operational complexity during actual misbehavior events.
3Reliability
If only the owner can decrypt and verify the data, then data integrity is ensured, but the verification process becomes more complex
Solution Approach 1:
The patent implements feedback through the verification process where the misbehavior managing authority decrypts the proprietary sensor data using private keys and compares it against expected values or patterns. This feedback mechanism confirms data integrity by verifying that the decrypted information matches the anticipated misbehavior conditions, providing a systematic way to ensure accuracy while managing the complexity through structured verification protocols.

AI summary
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.
