Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common authentication manner is used for security verification, then security reliability is improved, but authentication time increases significantly
Solution Approach 1:
The patent implements dynamic authentication mode selection that adapts between simple and common authentication manners based on real-time conditions. The system determines whether to use simple authentication (faster) or common authentication (more secure) dynamically, allowing it to balance security requirements with time constraints, thus resolving the contradiction between security reliability and authentication time.
Solution Approach 2:
The patent changes the authentication parameter (authentication manner) from a fixed state to a variable state. By introducing multiple authentication modes (simple and common) and selecting appropriate modes based on conditions, the system can adjust the security level and time consumption parameters, thereby resolving the contradiction between high security reliability and low authentication time.
2Loss of time
If simple authentication manner is used, then authentication time is reduced, but security reliability may be compromised
Solution Approach 1:
The system dynamically switches between simple and common authentication modes based on determined conditions. When simple authentication is used to reduce time, the system ensures security through conditional logic and fallback mechanisms, thus maintaining reliability while benefiting from reduced authentication time.
Solution Approach 2:
The authentication process is segmented into two distinct modes (simple and common), each suitable for different scenarios. This segmentation allows the system to choose the appropriate level of security and time investment based on specific conditions, resolving the contradiction between speed and security.
3Reliability
If multiple authentication technologies are implemented, then security coverage is improved, but system complexity increases
Solution Approach 1:
The authentication system is segmented into two distinct authentication manners (simple and common), each with its own protocol and verification steps. This segmentation allows the system to provide comprehensive security coverage while maintaining clear, manageable structure, thus reducing perceived complexity despite multiple authentication technologies.
Solution Approach 2:
The system dynamically selects which authentication technology to apply based on conditions, rather than always executing all authentication protocols. This dynamic selection reduces the effective complexity experienced during operation, while maintaining comprehensive security coverage when needed.

AI summary
The present invention relates to a method for securely connecting a vehicle and a Bluetooth key, a vehicle Bluetooth module and a Bluetooth key. The method comprises: when a vehicle Bluetooth module successfully establishes a Bluetooth communication connection with a mobile terminal installed with a Bluetooth key, the vehicle Bluetooth module receiving an authentication request from the Bluetooth key, wherein an authentication manner of the authentication request is simple authentication or common authentication; when the authentication manner of the authentication request is simple authentication, the vehicle Bluetooth module performing security authentication on the Bluetooth key according to the simple authentication manner, and sending an authentication result to the Bluetooth key; and when the authentication result indicates that authentication fails, or the authentication manner of the authentication request is common authentication, the vehicle Bluetooth module performing security authentication on the Bluetooth key according to the common authentication manner.
