Solution Overview

Problem

Current methods for validating vehicle authenticity are not cryptographically based, making modern vehicles susceptible to cyber and reverse engineering threats due to their increased software and firmware complexity, leading to vulnerabilities in wireless and cellular interfaces, and potential attacks through OTA updates and aftermarket devices.

Innovation Solution

A system and method for cryptographic verification of vehicle authenticity using a Vehicle Identification Number (VIN)-Key, which involves generating a VIN-Key for individual vehicles, applying it to components, validating authenticity through a security module, and logging operations to ensure immutable and cryptographically verified authenticity, using a symmetric split key for secure updates and firmware validation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cryptographic verification using VIN-Key is implemented, then vehicle authenticity and security are improved, but device complexity increases

Engineering Contradiction:
Improvevehicle authenticity verificationVSAvoidcryptographic system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-generating unique cryptographic key pairs for each vehicle during manufacturing. The public keys are embedded in the vehicle's hardware before deployment, establishing a root of trust that enables subsequent cryptographic verification operations without requiring complex real-time key generation or distribution infrastructure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces cryptographic certificates as intermediaries that bridge the vehicle's hardware identity and the verification system. These certificates contain public keys and vehicle identifiers, serving as mediating artifacts that enable secure authentication between vehicles and external systems without exposing private keys or requiring direct trusted communication channels.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If cryptographic verification is implemented across all vehicle components, then security against cyber threats is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecyber security protectionVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the cryptographic verification system into distinct modular components: hardware security modules for key storage, certificate management systems, and verification protocols. This segmentation allows each component to be developed, tested, and manufactured independently, reducing overall manufacturing complexity while maintaining comprehensive security coverage across vehicle components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a universal cryptographic verification framework that can be applied across diverse vehicle components and systems. The same VIN-Key infrastructure and certificate validation mechanism serve multiple functions including authentication, integrity verification, and authorization, eliminating the need for separate security implementations for different vehicle subsystems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If immutable cryptographic verification is applied to software and firmware updates, then protection against malicious code is improved, but update processing time increases

Engineering Contradiction:
Improvesoftware authenticity protectionVSAvoidupdate validation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-signing software and firmware updates with the vehicle's private key before deployment. The cryptographic signatures are attached to update packages in advance, allowing receiving systems to perform rapid verification by simply checking the signature against the stored public key, rather than performing complex authentication protocols during the update process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex mechanical or procedural verification methods with efficient cryptographic signature validation. Instead of requiring physical inspection, manual authentication, or multi-step verification processes, the system uses mathematical signature verification that can be performed rapidly by processors, significantly reducing update validation time while maintaining strong security guarantees.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
