Secure Vehicular Services Communication via Key Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular communication systems are insecure and vulnerable to nefarious activities due to unverified and public communication, which can negatively affect vehicle operations, especially in inclement weather conditions where camera and sensor operations are compromised.
Innovation Solution
A secure vehicular services communication system using external and vehicular communication components that exchange public keys for encrypting data and utilize private keys for decryption, along with certificates and signatures to verify identities and ensure data integrity, thereby preventing unauthorized access and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If public and unsecured communication is used between vehicular entities, then communication simplicity and ease of operation are improved, but security and reliability deteriorate due to vulnerability to nefarious activities
Solution Approach 1:
The patent introduces certificates and digital signatures as intermediary mechanisms between communicating vehicular entities. These intermediaries enable secure authentication and data integrity verification without requiring complex peer-to-peer cryptographic key management, thus maintaining ease of operation while significantly improving communication security and reliability
Solution Approach 2:
The system performs preliminary authentication actions by verifying certificates and digital signatures before establishing communication channels or accepting data exchanges. This preliminary verification prevents unauthorized access and ensures the reliability of subsequent communications, resolving the security-reliability contradiction
2Reliability
If cameras and sensors are used to obtain surrounding information, then vehicle operation safety is improved, but reliability deteriorates in inclement weather conditions where sensor operations are compromised
Solution Approach 1:
The patent uses V2X communication as an intermediary information source that provides surrounding vehicle and environmental data independent of weather conditions. This intermediary channel compensates for sensor failures in inclement weather, maintaining operational safety when primary sensors are compromised
Solution Approach 2:
The system obtains copied information about surrounding entities through V2X communication messages from other vehicles and infrastructure. These digital copies of environmental data provide redundant information that can be used when direct sensor observation is impaired by weather conditions

AI summary
Secure vehicular services communication is described herein. An example apparatus can include a processor and an external communication component. The external communication component can be coupled to the processor and can be configured to, in response to determining a vehicular entity is within a particular proximity to the external communication component, generate an external private key and an external public key, provide the external public key and data to a vehicular communication component associated with the vehicular entity, receive data from the vehicular communication component in response to providing the external public key and data to the vehicular communication component, decrypt the received data using the external private key, and provide a service to the vehicular entity based on the decrypted received data.
