Vehicle Secure Pairing via Multi-Key Startup Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for secure pairing of smartphones with vehicles are either too permissive, allowing unauthorized access, or overly restrictive with time delays, which can be inconvenient for authorized users.
Innovation Solution
A method that requires the use of two different vehicle keys to start the vehicle at different times to authorize a mobile device or application to access vehicle resources, ensuring only authorized users can pair and control vehicle functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct on-screen access via vehicle screen is used to pair a device, then pairing convenience is improved, but security is worsened allowing unauthorized access
Solution Approach 1:
The system requires the vehicle to be started with a key before pairing can occur. This preliminary action (starting the vehicle) ensures that only someone with physical access to a key can initiate pairing, preventing unauthorized pairing attempts without compromising the convenience of the pairing process itself.
2Reliability
If time delay is implemented following verification request, then security is improved to prevent immediate unauthorized access, but ease of operation is worsened making the process onerous
Solution Approach 1:
The patent extracts the time delay element from the verification process and replaces it with immediate verification based on key usage detection. The system continuously monitors for key-based vehicle startups and uses this information for immediate pairing decisions, eliminating the need for onerous time delays while maintaining security.
Solution Approach 2:
The system automatically detects when the vehicle is started with a key and uses this information to authorize pairing without requiring additional user actions or waiting periods. The verification process serves itself by utilizing the key startup event as the authentication mechanism, providing both security and convenience.
3Reliability
If multiple verification steps are required, then security is improved, but loss of time is increased
Solution Approach 1:
The key-based verification serves as a preliminary action that occurs naturally before pairing is requested. Since the user must start the vehicle with a key anyway to access vehicle functions, this preliminary action provides security verification without adding extra time to the pairing process.
Solution Approach 2:
The system continuously monitors for key-based vehicle startups and maintains readiness to authorize pairing immediately when the condition is met. This continuous monitoring eliminates gaps or delays in the verification process, allowing pairing to occur as soon as the security condition is satisfied without additional waiting time.

AI summary
A system includes a processor configured to receive a request from a mobile device to utilize a vehicle resource. The processor is also configured to determine that a first key has been used to start a vehicle a first time. The processor is further configured to determine that a second key has been used to start the vehicle a second time and approve the request based on the determination that both the first key and the second key were used to start the vehicle a first time and a second time respectively.
