Distributed Domain Management Information Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current domain management systems burden the domain authority with storage and maintenance tasks, requiring online access for domain management information exchange, which is inefficient and inconvenient, especially when domain managers need to be replaced.
Innovation Solution
Storing domain management information in member devices instead of the domain authority, using techniques like secret sharing to distribute and recover this information, allowing offline access and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If domain management information is stored in the domain authority, then the domain manager can retrieve information online, but the workload and storage burden on the domain authority becomes heavy
Solution Approach 1:
The patent segments the domain management information by distributing it across multiple member devices rather than centralizing it in the domain authority. Each member device holds a portion of the information (e.g., secret shares), which collectively reconstruct the full domain management information. This segmentation reduces the storage burden on the domain authority while maintaining online retrieval capability through distributed access.
2Adaptability or versatility
If domain management information is stored in the domain authority, then information can be centrally managed, but the system requires continuous online access which reduces convenience
Solution Approach 1:
The patent applies preliminary action by pre-distributing domain management information to multiple member devices before any domain manager needs to access it. This way, when a domain manager needs to retrieve information, they can do so offline from local member devices without requiring continuous online access to the domain authority, while the information remains centrally managed through the distributed architecture.
3Ease of operation
If domain management information is stored in a single location, then access is simple, but security is compromised if that location is breached
Solution Approach 1:
The patent segments domain management information into multiple parts and distributes them across different member devices. This segmentation maintains access simplicity because domain managers can still retrieve and reconstruct the information through standard protocols, while simultaneously improving security since compromising a single device does not expose the entire information set. The information remains reliable and secure through this distributed architecture.

AI summary
The invention proposes methods and devices for managing domains. The domains comprise a plurality of member devices, and the method comprises the steps of: storing (S500, S501), by a first domain manager (M1), domain management information (P1, P2, P3, P4 and P5) in said plurality of member devices; and obtaining (S510, S511), by a second domain manager (M2), said domain management information from at least one of said plurality of member devices. In comparison with the prior art, where the domain management information is maintained in the domain authority, the embodiment decreases the work load of the domain authority and provides conveniences.
