Vehicle Data Access Control Using Local Blockchain Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing access to vehicle data are inefficient, requiring large storage space and cumbersome key management in cloud databases, and lack agility in granting or revoking user permissions.
Innovation Solution
A method involving a vehicle generating user keys based on a vehicle root of trust key and user mobile device key, using blockchain to authenticate requests, and wrapping user keys with validity periods, allowing secure and agile access control without external cloud reliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud-based access control lists are used to manage vehicle data access, then user permissions can be controlled, but large storage space is required and the system becomes cumbersome and non-agile
Solution Approach 1:
The patent extracts the access control logic from centralized cloud databases and implements it locally in the vehicle using blockchain technology. Each vehicle maintains its own access control list on the blockchain, eliminating the need for large centralized storage while maintaining permission management capabilities
Solution Approach 2:
The vehicle system autonomously manages its own access control lists using blockchain technology, generating and updating permission data without requiring external cloud services. This self-service approach reduces storage requirements and eliminates dependency on centralized cloud infrastructure
2Reliability
If cloud-based access control lists are updated for each permission change, then user permissions can be granted or revoked, but the process becomes cumbersome and not agile
Solution Approach 1:
The patent implements dynamic access control where the vehicle can autonomously update its access control list on the blockchain in real-time based on permission changes. This dynamic local update mechanism eliminates the lag and complexity of centralized cloud updates, enabling agile permission management
Solution Approach 2:
The system pre-establishes the blockchain infrastructure and access control logic within the vehicle, enabling immediate permission changes without requiring preliminary cloud communication. Permission updates are executed locally and instantly recorded on the blockchain
3Reliability
If encryption keys are generated and stored in cloud key management systems, then data can be encrypted, but expensive infrastructure is required
Solution Approach 1:
The patent extracts key generation and storage functions from expensive cloud key management systems and implements them locally in the vehicle using blockchain technology. Encryption keys are generated and stored on the vehicle's blockchain, eliminating dependency on external key management infrastructure
Solution Approach 2:
The vehicle system autonomously generates and manages its own encryption keys using blockchain technology, without requiring external cloud-based key management services. This self-service approach to key management eliminates infrastructure costs while maintaining strong encryption capabilities

AI summary
Provided are a method, system, and device for optimizing performance of a vehicle. The method may include, receiving vehicle condition data prior to operating the vehicle; generating, based on the vehicle condition data, input data for a machine learning (ML) model, wherein the ML model is configured to output at least one of predicted vehicle performance and vehicle parameters based on the vehicle condition data; suggesting, by the ML model, optimized vehicle parameters based on the input data; and sending, based on the optimized vehicle parameters, instructions to tune the vehicle.
