Trusted Computing Cluster Formation via Parallel Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a trusted computing cluster involving a large number of trusted computing units is time-consuming under conventional methods.
Innovation Solution
The method involves grouping N trusted computing units into groups with each group having a number of units not greater than K+1, performing parallel inter-unit and inter-group trust authentications, and propagating a secret key among units that successfully authenticate, allowing all units to obtain the same secret information to form the trusted cluster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to establish a trusted computing cluster with a large number of trusted computing units, then the trust authentication can be performed sequentially, but the time required for establishing the cluster becomes very long
Solution Approach 1:
The patent divides the N trusted computing units into multiple groups, where each group contains at most K+1 units. This segmentation allows parallel trust authentication within each group, reducing the overall time required while maintaining reliable authentication for all units.
Solution Approach 2:
The patent transitions from sequential authentication to parallel authentication by introducing multiple groups that can authenticate simultaneously. This dimensional change from single-threaded to multi-threaded processing significantly reduces the time required to establish the trusted computing cluster.
2Productivity
If parallel trust authentication is performed among multiple groups, then the time required for establishing the cluster is reduced, but the system complexity increases
Solution Approach 1:
By segmenting units into groups of at most K+1 units, the patent manages complexity through structured organization. Each group performs authentication independently, and the grouping strategy provides a clear framework for coordinating multiple parallel operations without overwhelming system complexity.
Solution Approach 2:
The patent introduces group-level coordination as an intermediary mechanism between individual unit authentication and final cluster formation. This intermediary layer simplifies the overall system by providing structured coordination protocols for parallel operations.
3Quantity of substance
If a large number of trusted computing units are involved, then the cluster becomes more powerful, but the time required for trust authentication and key propagation increases
Solution Approach 1:
The patent segments N units into multiple groups of at most K+1 units each, enabling parallel authentication across all groups. This segmentation allows the system to scale with the number of units while maintaining constant authentication time per group, thus reducing overall establishment time as N increases.
Solution Approach 2:
The patent introduces parallel processing as a new dimension of operation, transforming the authentication process from sequential to concurrent. This allows the system to handle larger numbers of units efficiently by performing multiple authentication operations simultaneously rather than sequentially.

AI summary
The implementations provide a method and an apparatus for establishing a trusted cluster. The method is used to form a trusted computing cluster by using N trusted computing units, the method including: grouping the N trusted computing units into a plurality of groups; identifying a first trusted computing unit in each group, and causing first trusted computing units in the plurality of groups to each respectively perform inter-unit trust authentication with other trusted computing units in a same group in parallel; performing inter-group trust authentication between/among the plurality of groups in parallel to obtain the N trusted computing units on which trust authentication succeeds; and propagating secret information in the N trusted computing units on which trust authentication succeeds, so that the N trusted computing units obtain the same secret information to form the trusted computing cluster.
