Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by pre-distributing cryptographic keys to vehicles during manufacturing before they are deployed. This ensures that secure communication capabilities are established in advance, eliminating the need for complex runtime key distribution and reducing vulnerability to interception attacks.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical certificate-based authentication systems with a quantum-inspired cryptographic approach. This substitution introduces fundamentally secure key distribution mechanisms that are resistant to interception and decryption, addressing the vulnerability of conventional systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex quantum key distribution and blockchain verification operations from the vehicle's onboard systems and relocates them to centralized infrastructure components. This extraction reduces the computational burden and complexity within individual vehicles while maintaining the security benefits of these advanced cryptographic techniques.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a cryptographic service provider as an intermediary that manages the complex key distribution and verification processes. This mediator handles the computationally intensive quantum-inspired cryptographic operations, allowing vehicles to benefit from enhanced security without bearing the full complexity burden.

Inventive Principle:

Solution Approach 1:

The patent performs preliminary key distribution during the vehicle manufacturing process itself, integrating cryptographic module installation and key provisioning into the existing production line. This approach amortizes the manufacturing cost across the production process and avoids requiring expensive post-manufacturing interventions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cryptographic system is designed to be self-configuring and self-provisioning, automatically generating and distributing keys without requiring manual intervention during manufacturing. This self-service capability significantly reduces labor costs and simplifies the manufacturing process while maintaining high security standards.

AI summary

In accordance with an embodiment, a method for delivering a certificate to a vehicle comprising transmitting the certificate to the vehicle via near field coupling is provided. The near field coupling can be accomplished by transmitting data using a near field coupled antenna to a receiver. The near field coupled antenna can also be used for content delivery such as for example, a streaming video signal, a streaming webcast signal, non-streaming transfer of information, etc. The method can be used for location validation of land vehicles, marine vehicles, and pedestrians as well as content delivery, and payment mechanisms. In accordance with another embodiment a traffic control system is configured to control vehicles and pedestrians in an intelligent transportation system.
