Vehicle Authentication Switching During Server Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation systems face a decline in functionality when communication with a server is interrupted, leading to a state where vehicle operations become impossible.
Innovation Solution
A terminal system that switches between using tokens for authentication based on communication status, employing tokens when connected to a server and omitting tokens for low-security operations when disconnected, while ensuring secure authentication and notifying users of token depletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tokens are used for authentication when communication with the server is interrupted, then security of the vehicle is improved, but the terminal may decline into a state in which operation of the vehicle is not possible due to insufficient tokens
Solution Approach 1:
The patent applies local quality by differentiating authentication methods based on the operation type. Low-security operations (door locking) use token-less authentication when disconnected, while high-security operations (engine starting) require tokens. This localized approach to security ensures vehicle operability for essential functions while maintaining security for critical functions, resolving the contradiction between operation availability and token conservation.
2Reliability
If tokens are used for every authentication operation, then security of the vehicle is assured, but operation of the vehicle becomes impossible when communication with the server is interrupted and tokens are depleted
Solution Approach 1:
The patent segments authentication operations into two categories: high-security operations (engine starting, vehicle movement) requiring tokens, and low-security operations (door locking, window control) that can use token-less authentication when disconnected. This segmentation allows the system to maintain security for critical functions while ensuring operability for essential functions, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The patent changes the authentication parameter dynamically based on communication status and operation type. When connected to the server, the system uses token-based authentication. When disconnected, it switches to token-less authentication for low-security operations. This parameter change enables the system to adapt to different conditions, maintaining both security and operability.
3Reliability
If communication with the server is maintained continuously to ensure token supply, then vehicle operation is always possible, but the system becomes vulnerable to frequent communication interruptions in areas like underground parking garages
Solution Approach 1:
The patent makes the authentication system dynamic by adapting to communication conditions. When the terminal is connected to the server, it uses token-based authentication. When communication is interrupted, it dynamically switches to token-less authentication for low-security operations. This dynamic adaptation ensures the system remains functional across varying communication environments, from well-connected areas to underground parking garages.

AI summary
A vehicle operation device comprises a storage section and an authentication section. The storage section stores a token to be used for authentication to a vehicle. The token is received from a server. The authentication section, when an operation of the vehicle is performed in a state in which communication with the server is possible, uses the token to conduct authentication to the vehicle. Further, the authentication section, when a predetermined operation of the vehicle is performed in a state in which communication with the server is interrupted, conducts authentication to the vehicle without using the token.
