Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an efficient and secure method for verifying the configuration information of in-vehicle devices, which is crucial for ensuring vehicle security and preventing tampering.
Innovation Solution
A data verification method and apparatus that involves a first in-vehicle device receiving verification information from a second in-vehicle device, using this information to verify the configuration data of the second device stored in both devices, thereby ensuring secure and efficient verification without the need for additional verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional verification methods are used for configuration information of in-vehicle devices, then verification can be performed, but the verification process becomes complex and security is not sufficiently improved
Solution Approach 1:
The patent applies preliminary action by pre-storing configuration information of the second in-vehicle device in the first in-vehicle device before verification is needed. This allows the verification process to simply compare the received configuration information against the pre-stored copy, eliminating complex verification procedures while maintaining high security standards.
2Reliability
If additional verification processes are implemented to improve security, then security of configuration information is enhanced, but verification difficulty and system complexity increase
Solution Approach 1:
The patent implements self-service by having the first in-vehicle device automatically perform verification of the second device's configuration information using the pre-stored configuration data. The system serves itself by comparing configurations without requiring external verification authorities or complex multi-step validation processes, thereby maintaining high security while simplifying operations.
3Reliability
If configuration information is stored only in the original device, then storage is simplified, but security protection against tampering is insufficient
Solution Approach 1:
The patent uses an intermediary approach by introducing the first in-vehicle device as a verification intermediary that holds a copy of the second device's configuration information. This intermediary device enables security verification without requiring the second device to carry its own verification mechanisms, thus enhancing security while keeping the verification process simple.
Data Source
AI summary
Example data verification methods and apparatus are described. One example method is applied to a first device in a vehicle, where the vehicle includes the first device and a second device. The first device receives a first message from the second device, where the first message includes first verification information, the first verification information is used to perform verification on first data, and the first data is configuration information of the second device that is stored in the second device. The first device performs verification on the first data based on configuration information of the second device that is stored in the first device and the first verification information.
