Decentralized Ledger Synchronization for Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security technologies face challenges in managing and controlling local area network security effectively, particularly due to the reliance on third-party servers which can lead to increased maintenance costs and potential security failures if the server is down or experiences abnormalities.
Innovation Solution
A device abnormality detection method and system that synchronizes ledger data changes among network devices, allowing any network device to determine if the system is abnormal based on difference data, thereby decentralizing security control and reducing reliance on a single server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a third-party server is introduced to manage and control network security, then security management capability is improved, but system reliability deteriorates due to single point of failure
Solution Approach 1:
The patent divides the centralized security management function into distributed segments across multiple network devices. Each network device maintains local ledger data and can independently perform security control operations, eliminating dependency on a single third-party server and improving system reliability while preserving security management capabilities.
Solution Approach 2:
The patent enables network devices to perform self-management of security control functions. Each device can synchronize its own ledger data, detect abnormalities, and execute security policies independently without requiring continuous server intervention, thereby improving reliability while maintaining operational capability.
2Ease of operation
If a third-party server is used for security control, then centralized security management is improved, but device complexity increases due to server maintenance requirements
Solution Approach 1:
The patent extracts the security control functionality from the third-party server and distributes it to individual network devices. Each device maintains local copies of ledger data and can independently execute security policies, eliminating the need for complex server maintenance while preserving centralized management capabilities through peer-to-peer coordination.
Solution Approach 2:
The patent implements multiple copies of ledger data across different network devices instead of relying on a single server database. This replication approach allows any device to function independently even if others are unavailable, reducing maintenance complexity while maintaining centralized security management through data synchronization.
3Reliability
If ledger data is synchronized to all network devices, then security control reliability is improved, but data transmission overhead increases
Solution Approach 1:
The patent implements selective synchronization where network devices transmit only the necessary ledger data changes rather than synchronizing entire datasets. This partial action approach maintains security control consistency across all devices while significantly reducing data transmission overhead and energy consumption compared to full synchronization.

AI summary
The present disclosure provides a device abnormality detection method and a device networking system. The method includes if ledger data of a specific network device in the plurality of network devices changes, synchronizing, by the specific network device, ledger data after the change or difference data to other network devices than the specific network device in the device networking system, where the specific network device is any network device in the device networking system, and the difference data is changed data in the ledger data; and further includes determining whether the plurality of network devices is abnormal according to the difference data.
