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 information within 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 information in sensor data is transmitted over public networks for misbehavior reporting, then the misbehavior reporting function is enabled, but the confidentiality and security of proprietary information is compromised
Solution Approach 1:
The patent introduces encryption as an intermediary mechanism between the sensor data and the public network transmission. The proprietary information is encrypted before transmission, and only the misbehavior managing authority possesses the decryption keys. This intermediary encryption layer enables the misbehavior reporting function while protecting the confidentiality of proprietary information during transmission over public networks.
2Object-affected harmful factors
If proprietary information is encrypted before transmission, then the confidentiality of sensor data is protected, but the complexity of the reporting system increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing encryption keys and encryption schemes before the misbehavior reporting process begins. The proprietary information is encrypted in advance using predetermined keys, and the encrypted data is stored ready for transmission. This preliminary preparation reduces the complexity during actual reporting operations, as the encryption infrastructure is already in place rather than being established ad hoc.
3Reliability
If encrypted proprietary information is transmitted in misbehavior reports, then the security of V2X communication is improved, but the processing and verification complexity at the receiving end increases
Solution Approach 1:
The patent introduces a key management intermediary system where the misbehavior managing authority holds and manages the decryption keys. Rather than requiring complex verification processing at multiple receiving endpoints, the key management intermediary centralizes the decryption capability. This allows encrypted proprietary information to be transmitted securely while simplifying the verification process at the receiving end, as only the authorized authority needs to perform decryption.

AI summary
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.
