Vehicle V2V Communication Key Exchange for Identification Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle (V2V) communication systems struggle to accurately identify and receive data from specific vehicles, particularly those ahead, leading to inefficiencies in sharing traffic information and views between vehicles.
Innovation Solution
A method and system that obtain identification information of a first vehicle from a second vehicle using spatial proximity, acquire a corresponding key pair, and process data signed with a second key to verify and display or transmit the identified data, enabling secure and specific data exchange between vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If V2V communication systems use traditional identification methods, then vehicles can exchange data, but they cannot accurately identify and receive data from specific vehicles ahead
Solution Approach 1:
The patent segments the V2V communication process into distinct phases: identification information acquisition, key pair acquisition, data identification, and data processing. This segmentation allows each phase to be optimized independently, improving both identification accuracy and communication efficiency.
Solution Approach 2:
The patent performs preliminary actions by acquiring identification information and key pairs before actual data exchange occurs. This preliminary setup enables accurate vehicle identification and secure communication to be established in advance, resolving the contradiction between identification accuracy and communication efficiency.
2Reliability
If V2V systems implement secure data exchange with key pairs, then data security is improved, but system complexity increases
Solution Approach 1:
The patent introduces key pairs as intermediary elements that mediate between vehicles for secure communication. The first key identifies data origin, while the second key verifies authenticity. This intermediary mechanism provides security without requiring complex direct verification protocols between vehicles.
Solution Approach 2:
The patent uses identification information (such as vehicle identifiers) as a copy or representation of the actual vehicle identity. This allows vehicles to be identified and authenticated without exposing sensitive information, simplifying the security system while maintaining reliability.
3Measurement precision
If V2V communication uses detailed vehicle identification, then data source verification is improved, but information processing time increases
Solution Approach 1:
The patent extracts only the essential identification information and key pair elements needed for verification, separating them from the actual data payload. This extraction allows rapid verification of data sources without processing unnecessary information, reducing time loss while maintaining verification accuracy.
Data Source
AI summary
A method, system and computer program product for wireless communication between vehicles are provided. In the method, identification information of a first vehicle by a second vehicle being spatially close to the first vehicle is obtained. And a first key associated with the first vehicle by using the identification information is acquired. Data originated from the first vehicle and signed with a second key corresponding to the first key are identified with the first key. And then the identified data is processed.
