Verified Analysis Log Management for Vehicle Cyberattack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to validate the validity of communication traffic data, leading to inappropriate storage and transmission of invalid logs, increasing storage capacity and inefficiencies in managing analysis logs.
Innovation Solution
A management device that includes an obtainer to collect logs and verification data, a verifier to validate the logs, and a controller to manage storage and transmission based on verification results, ensuring valid logs are stored and invalid logs are identified and managed appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all communication traffic data is stored without validation, then no valid logs are lost, but storage capacity increases and management efficiency decreases
Solution Approach 1:
The patent applies preliminary action by performing validation checks on logs before they are stored in the database. The validation process verifies the integrity and authenticity of logs using verification data (such as digital signatures or hash values) before storage, ensuring that only valid logs are stored. This prevents invalid logs from occupying storage space, thereby resolving the contradiction between maintaining reliability and reducing storage capacity requirements.
2Reliability
If all communication traffic data is stored without validation, then no valid logs are lost, but management efficiency decreases
Solution Approach 1:
The patent performs validation checks on logs before they are stored in the database. The validation process verifies the integrity and authenticity of logs using verification data (such as digital signatures or hash values) before storage, ensuring that only valid logs are stored. This prevents invalid logs from occupying storage space, thereby resolving the contradiction between maintaining reliability and reducing storage capacity requirements.
Solution Approach 2:
The patent extracts and removes invalid logs from the storage process by implementing a validation filter. The validation mechanism identifies and excludes invalid logs (those with mismatched verification data, tampered content, or unauthorized sources) before they can be stored or processed further. This extraction of harmful elements (invalid logs) improves management efficiency by reducing the volume of data that needs to be managed while maintaining high reliability through selective storage of only valid logs.
3Reliability
If verification process is implemented, then log validity is ensured, but processing complexity increases
Solution Approach 1:
The patent introduces an intermediary verification mechanism that acts as a mediator between log generation and log storage. The verification process uses pre-shared verification data (such as digital signatures, hash values, or authentication tokens) that were established during system initialization or key distribution. This intermediary validation layer ensures log authenticity without requiring complex real-time analysis, thereby maintaining reliability while controlling processing complexity through the use of established cryptographic or validation protocols.
Data Source
AI summary
A management device includes: an obtainer that obtains, from a processing device, a log of operation performed by the processing device and verification data for certifying that the log is valid information; a verifier that performs verification of whether the log is valid information, based on the verification data obtained by the obtainer; and a controller that performs storage control for storing the log as an analysis log for analyzing an anomaly into a storage device, in accordance with a result of the verification performed by the verifier.
