Vehicle Quantum Encryption for Road-Cloud Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-road-cloud collaboration systems lack sufficient confidentiality in communication, making them vulnerable to hacking and data security threats, especially since traditional quantum encryption requires wired connections, which are not suitable for moving vehicles, and vehicle data ownership is contentious.
Innovation Solution
A system for vehicle encrypted communication using a vehicle-side communication unit with a first quantum random number generator, quantum key management module, on-vehicle communication module, user authorization module, certificate management module, and quantum encryption and decryption module, along with a second quantum random number generator on the visitor side, to establish secure communication connections using digital certificates and quantum keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional quantum encryption using fiber channels is used, then communication security is improved, but adaptability to moving vehicles deteriorates
Solution Approach 1:
The patent replaces the mechanical fiber optic connection system with a satellite-based quantum communication system. The quantum key distribution is achieved through satellite transmission rather than wired fiber connections, enabling secure communication for moving vehicles without requiring physical fiber infrastructure. This substitution resolves the contradiction by maintaining quantum security while removing the mobility constraint.
2Ease of operation
If vehicle data is stored in manufacturer servers, then data management is simplified, but data ownership control by users deteriorates
Solution Approach 1:
The patent segments data storage and management into multiple distributed locations including user devices, manufacturer servers, and third-party platforms. Each entity maintains appropriate levels of control over their portion of the data ecosystem. This segmentation allows simplified centralized management where needed while preserving user sovereignty and control rights over personal vehicle data through distributed architecture.
Solution Approach 2:
The patent introduces third-party data management platforms as intermediaries between users and manufacturers. These intermediaries facilitate data access and control according to user-defined policies, enabling users to maintain ownership and control while still allowing manufacturers and service providers to access necessary data through authorized channels.

AI summary
System for vehicle encrypted communication for vehicle-road-cloud collaboration is provided. The system includes a vehicle-side communication unit disposed on a vehicle and a second quantum random number generator disposed on a visitor. The vehicle-side communication unit includes a first quantum random number generator, a quantum key management module, an on-vehicle communication module, a user authorization module, a certificate management module, and a quantum encryption and decryption module. The visitor generates an access request and sends the access request to the vehicle, after the on-vehicle communication module receives the access request, the user checks the access request and decides whether to authorize the access request through the user authorization module, and in response to the access request of the visitor B being authorized, the certificate management module generates a digital certificate corresponding to the access request, and the on-vehicle communication module sends the digital certificate to the visitor.
