Sponsored Trust Management for Multi-Rack Data Centers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing trust relationships between multiple racks in a data center is inefficient and inflexible, requiring multiple operations and needing all management nodes to be online.
Innovation Solution
A sponsored trust relationship approach where a new management node can establish trust with other management nodes through a first management node, using public keys and access tokens to simplify and expedite the process, allowing any management node to sponsor a new node and enabling trust establishment even if only one node is online.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional trust establishment methods are used between multiple racks, then security and trust relationships are maintained, but the process requires multiple operations and all management nodes to be online, reducing efficiency
Solution Approach 1:
The patent introduces a sponsor management node as an intermediary that facilitates trust relationship establishment between new and existing management nodes. The sponsor node generates access tokens and public keys that enable the new node to establish trusted connections with other nodes in the system, eliminating the need for all nodes to be online simultaneously and reducing the number of direct operations required.
2Reliability
If traditional trust establishment methods are used, then comprehensive trust relationships are established, but the process is inflexible and requires all management nodes to be online
Solution Approach 1:
The sponsor management node performs preliminary actions by pre-generating access tokens and public keys before the new management node joins the system. This preliminary preparation allows the new node to establish trust relationships upon arrival without requiring all other nodes to be online, providing flexibility while maintaining complete trust relationship establishment.
3Reliability
If multiple operations are performed for trust establishment, then comprehensive security is achieved, but the complexity and time required increases
Solution Approach 1:
The patent merges multiple trust establishment operations into a single streamlined process. The sponsor node combines the generation of access tokens, public key distribution, and trust relationship validation into one coordinated operation, reducing the total time required while maintaining comprehensive security through the use of cryptographic mechanisms.

AI summary
A new management node associated with a new rack sends at least a public key of the new management node to a first management node associated with a first rack and a plurality of autonomous management nodes. The first management node sends the new management node an access token trusted by at least a portion of the plurality of autonomous management nodes and a set of public keys corresponding to at least a portion of the plurality of autonomous management nodes. The new management node can send its public key and the access token to at least a portion of the plurality of autonomous management nodes. In response, the new management node can establish a mutual trust relationship with at least a portion of the plurality of autonomous management nodes.
