Secure Connection Authorization via Logical Identifier Certificates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large clusters of interconnected computers, managing secure connections between nodes without specific node configurations, certificate pinning, or user input is impractical, especially when nodes are frequently replaced, scaled, or regrouped.
Innovation Solution
Nodes exchange device identifier certificates as part of a preliminary process to determine authorization for secure connections, relying on logical identifiers within the certificates to establish whether nodes belong to the same cluster or group, thereby automating the secure connection setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration and certificate pinning are used to manage secure connections, then connection security is improved, but device complexity and ease of operation deteriorate in large clusters
Solution Approach 1:
The system enables nodes to automatically establish secure connections by exchanging certificates and comparing logical identifiers without manual configuration. Each node independently determines whether to establish secure connections by validating certificates and comparing its own logical identifiers with those in received certificates, eliminating the need for centralized certificate pinning or manual setup.
Solution Approach 2:
Logical identifiers are pre-configured in nodes before they join the cluster. When nodes exchange certificates, they can immediately determine compatibility by comparing these pre-configured identifiers, enabling rapid automatic connection establishment without requiring manual certificate pinning or configuration during node addition.
2Reliability
If manual configuration is used for secure connections, then connection authorization is improved, but productivity and ease of operation worsen when nodes are frequently replaced or scaled
Solution Approach 1:
Nodes automatically determine authorization to establish secure connections by comparing logical identifiers in exchanged certificates. When a node receives a certificate, it extracts the logical identifier, compares it with its own pre-configured identifier, and autonomously decides whether to establish a secure connection, eliminating manual authorization steps.
Solution Approach 2:
Logical identifiers are configured in advance in each node, enabling immediate authorization verification when nodes are added, replaced, or scaled. This preliminary configuration allows nodes to rapidly determine connection authorization through automatic certificate comparison without requiring manual setup or approval processes.
3Reliability
If certificate pinning is used to manage secure connections, then security is improved, but adaptability worsens in dynamic cluster environments
Solution Approach 1:
Nodes are pre-configured with logical identifiers that represent their cluster membership. When nodes join or leave the cluster, they exchange certificates containing these identifiers, and automatic comparison determines secure connection eligibility. This approach maintains security through identifier verification while adapting automatically to cluster changes without requiring certificate updates or re-pinning.
Solution Approach 2:
The system dynamically adapts to cluster changes by enabling nodes to automatically establish or terminate secure connections based on real-time certificate exchange and logical identifier comparison. When nodes are added, removed, or regrouped, the automatic verification process immediately determines new connection relationships, providing both security and adaptability to dynamic environments.

AI summary
A process includes communicating by a first device, with a second device. The communicating includes the first device receiving data from the second device that represents a certificate. The certificate binds a hierarchy of logical identifiers to a cryptographic key. The hierarchy of identifiers includes a first logical identifier that corresponds to a group membership. The process includes authenticating, by the first device, the second device based on the certificate. The process includes allowing, by the first device, a secure connection to be set up between the first device and the second device based on whether the first logical identifier represents that the second device is a member of a first group of devices of which the first device is a member.
