Cryptographic Identity Assignment for Multi-Node Complex Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Node-based systems suffer from increased latency and complexity in authentication and management due to individual node authentication, especially in multi-node complexes, and fail to efficiently handle node additions or removals.
Innovation Solution
Represent a multi-node complex as a single entity using a cryptographic identifier assigned to a controller node, allowing the complex to be authenticated and managed as a unified entity rather than individual nodes, thereby eliminating the need for repeated node authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual node authentication is performed in multi-node complexes, then security and authentication reliability are improved, but authentication latency and system complexity increase
Solution Approach 1:
The patent merges multiple individual node authentication operations into a single complex-level authentication operation. By creating a cryptographic representation of the entire multi-node complex and authenticating this single representation, the system maintains security (all nodes are verified) while dramatically reducing authentication latency from multiple sequential operations to one operation.
Solution Approach 2:
The patent performs preliminary actions by pre-computing cryptographic representations (hashes or signatures) of node identifiers and storing them in a database before authentication is needed. During authentication, the system simply compares the presented cryptographic representation against the pre-computed one, eliminating the need for real-time verification of each individual node and reducing authentication latency.
2Reliability
If individual node authentication is performed in multi-node complexes, then authentication security is improved, but device complexity increases
Solution Approach 1:
The patent merges the management of multiple individual node identities into a single complex-level cryptographic identity. Instead of tracking and managing authentication credentials for each node separately, the system creates one cryptographic representation that encompasses all nodes in the complex, thereby reducing system complexity while maintaining security through the use of cryptographic verification.
Solution Approach 2:
The patent creates a cryptographic copy or representation of the multi-node complex's identity that can be used for authentication purposes. This cryptographic representation (hash or signature) serves as a simplified surrogate for the complex's actual composition, allowing the system to authenticate the entire complex without directly managing or tracking each individual node's credentials, thus reducing complexity.
3Adaptability or versatility
If nodes are dynamically added or removed from the complex, then system adaptability is improved, but management complexity increases due to tracking individual nodes
Solution Approach 1:
The patent implements a dynamic system where the cryptographic representation of the complex can be updated as nodes are added or removed. The system recalculates the cryptographic hash or signature based on the current set of node identifiers, allowing the complex's identity to automatically adapt to changes in its composition without requiring manual reconfiguration or complex tracking logic for individual nodes.

AI summary
Examples disclosed herein relate to systems and methods for assigning an identifier to a node-based system. For example, systems and methods may: discover the plurality of nodes; determine a node of the plurality of nodes to be a controller node: authenticate, at a management component of the controller node, a respective identifier associated with each node of the plurality of nodes; and based on the authentication, assign a complex identifier to a complex comprising the plurality of nodes, wherein the complex identifier comprises the identifier associated with the controller node.
