Solution Overview

Problem

Existing endpoint configurations for secure data transmission in overlay networks are complex, costly, and error-prone, requiring cumbersome reconfiguration when network units are added or removed, which can compromise data security.

Innovation Solution

A decentralized system with endpoints that encrypt and decrypt data, establishing secure connections based on predecessor and successor relationships, allowing for self-configuration and secure data transmission without relying on central management, using secure tunnels and cryptographic methods to ensure data integrity and privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional endpoint configurations are used for secure data transmission, then data security can be maintained, but the system complexity and reconfiguration effort increase significantly when networks are added or removed

Engineering Contradiction:
Improvedata securityVSAvoidconfiguration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The endpoint automatically performs self-configuration by generating its own cryptographic key pair, deriving encryption parameters from its public key, and autonomously establishing secure connections to neighboring endpoints without requiring manual configuration or centralized management. This eliminates the need for administrators to manually configure each endpoint while maintaining security through cryptographic methods.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The endpoint pre-generates its cryptographic key pair and stores it in non-volatile memory before joining the network. This preliminary action allows the endpoint to immediately participate in secure communications upon network attachment without requiring time-consuming configuration steps, resolving the contradiction between security and configuration complexity.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual reconfiguration is performed when networks are added or removed, then security parameters can be maintained, but time and administrative effort are consumed

Engineering Contradiction:
Improvesecurity parameter consistencyVSAvoidreconfiguration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

When an endpoint joins or leaves the network, the system automatically detects the change and the remaining endpoints self-reconfigure by establishing new secure connections to their new neighbors. This eliminates manual reconfiguration time while maintaining security parameter consistency through automated cryptographic key exchange and connection establishment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The network topology is designed to be dynamic, allowing endpoints to be added or removed without disrupting the overall security structure. The system adapts to topological changes in real-time through automated connection re-establishment, eliminating the need for static configuration and reducing reconfiguration time while maintaining security.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If centralized management is used to configure endpoints, then configuration control is improved, but the system becomes vulnerable to single points of failure and management bottlenecks

Engineering Contradiction:
Improveconfiguration controlVSAvoidsystem availability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The centralized configuration authority is segmented and distributed to each individual endpoint. Each endpoint independently generates its own cryptographic keys and configuration parameters, eliminating the single point of failure represented by a centralized configuration server. This distributed approach maintains configuration control at the endpoint level while improving system availability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Cryptographic public keys serve as intermediaries that enable secure communication and configuration exchange without requiring direct trust or centralized management. Endpoints can securely exchange configuration information and establish connections through public key verification, eliminating the need for a centralized configuration authority while maintaining operational control and system reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The method involves arranging secure networks (N1-N5) adjacent to each other, and associating end points (E1-E5) with the respective networks. The networks are integrated in a higher-level network structure via the end points. An inner network (N6) is arranged in the secure network (N1). An address of an end point (E6) of the inner network is made invisible and/or unreadable for an insecure network (Nu). A connection between the secure networks is established during an initialization process, where the connection is provided for data transport via a secure tunnel.
