Vehicle Communication Apparatus Authentication for Security Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems face a trade-off between responsiveness and security, where increasing bit rate to improve responsiveness degrades noise resistance, and the current authentication processes cause time loss and decline in responsiveness when executed frequently for user requests.
Innovation Solution
A communication apparatus that executes a first authentication process upon door closure to determine if a specific mobile device is inside the vehicle for high-security operations, allowing subsequent operations to be performed without re-authentication, and uses a second authentication process for lower-security operations like door locking, improving responsiveness while ensuring security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is executed every time a vehicle operation is requested, then security is ensured, but responsiveness to user requests declines due to time loss
Solution Approach 1:
The system executes the first authentication process in advance when the door is closed, determining whether the mobile device is inside the vehicle before operations are needed. This preliminary authentication result is then reused for subsequent operations, eliminating the need to repeat authentication and thus improving responsiveness while maintaining security.
2Speed
If bit rate is increased to improve responsiveness, then responsiveness is improved, but noise resistance degrades
Solution Approach 1:
The authentication system is divided into multiple authentication processes (first authentication process for high-security operations, second authentication process for lower-security operations) with different security levels and processing requirements. This segmentation allows the system to use appropriate authentication intensity for each operation type, improving overall responsiveness without compromising security where needed.
Solution Approach 2:
Different authentication processes are applied to different vehicle operations based on their security requirements. The first authentication process is used for high-security operations like vehicle startup, while the second authentication process is used for lower-security operations like door locking. This local differentiation of authentication quality optimizes both security and responsiveness for each specific operation.

AI summary
A communication apparatus executes authentication via wireless communication with a mobile device and, based on an authentication process, controls execution of a vehicle operation requested by a user. The communication apparatus includes a detection unit configured to detect closure of a door of a vehicle, an authentication processing unit configured to determine, in response to detection of the closure of the door by the detection unit, whether a specific mobile device is inside the vehicle by executing a first authentication process corresponding to a vehicle operation for which a highest security is set, among a plurality of vehicle operations that can be requested by the user, and an execution unit configured to execute, when the authentication processing unit has determined that the specific mobile device is inside the vehicle, a requested vehicle operation requestable from an inside of the vehicle and included in the plurality of vehicle operations.
