Solution Overview
Problem
There is a need for enhanced data security in vehicle communication environments, particularly as more vehicles are equipped with extra-vehicular communication systems, where existing technologies lack effective security measures to protect data transmission and storage.
Innovation Solution
A blockchain system is implemented, utilizing a mesh network of vehicles with a center node and member nodes, where cryptographic data is exchanged using a star network topology and a gossip algorithm, enabling secure blockchain transactions and distributed storage across vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles are equipped with extra-vehicular communication systems, then communication capability is improved, but data security deteriorates
Solution Approach 1:
The system segments the communication network into a mesh network topology where multiple vehicles act as independent nodes. Each vehicle computer independently validates and stores blockchain transactions, distributing security responsibilities across multiple segmented units rather than relying on a centralized security mechanism. This segmentation allows the system to maintain communication versatility while improving data security through distributed validation.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between communication systems and data storage. The blockchain acts as a mediator that provides cryptographic verification and immutable recording of transactions, separating the communication function from the security function. This intermediary mechanism enables vehicles to communicate freely while maintaining robust data security through cryptographic protocols.
2Reliability
If blockchain transactions are disseminated to all member nodes, then data integrity is improved, but communication overhead increases
Solution Approach 1:
Each vehicle computer in the mesh network serves multiple functions: it acts as a communication node, a validation node, and a storage node for the blockchain. This multi-functionality allows the system to disseminate transactions to all member nodes for integrity verification while utilizing the existing communication infrastructure efficiently, reducing the need for separate dedicated communication channels and minimizing additional overhead.
Solution Approach 2:
The system implements a self-service mechanism where each vehicle computer autonomously validates incoming blockchain transactions and stores them locally. Member nodes independently verify transactions using cryptographic proofs without requiring centralized coordination for each validation step. This self-service approach distributes the computational workload across all nodes, maintaining data integrity through universal validation while reducing communication overhead by eliminating the need for centralized verification requests.
