Solution Overview

Problem

Current position-based routing technologies prioritize efficiency over security, making networks vulnerable to cyber attacks like man-in-the-middle attacks, especially in routing data through unauthenticated network nodes.

Innovation Solution

Implementing a method for secure routing that uses the physical locations of network nodes to enforce security constraints, such as routing data through nodes authenticated by satellite geolocation or network ping ranging measurements, and employing encrypted tunneling for unverifiable nodes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If position-based routing is used to optimize network route efficiency, then routing speed and resource utilization are improved, but network security deteriorates due to vulnerability to cyber attacks like man-in-the-middle attacks

Engineering Contradiction:
Improverouting efficiencyVSAvoidnetwork security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary authentication of network nodes using satellite geolocation and network ranging measurements before routing data through them. This advance verification ensures that only authenticated nodes are included in the routing path, preventing man-in-the-middle attacks while maintaining efficient position-based routing for authenticated nodes

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces encrypted tunneling as an intermediary mechanism for data transmission through unverifiable network nodes. The encryption layer acts as a mediator that protects data integrity and confidentiality even when passing through potentially compromised nodes, allowing efficient routing while mitigating security risks

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If satellite geolocation authentication is implemented for all network nodes, then network security is improved, but system complexity and authentication time increase

Engineering Contradiction:
Improveauthentication securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system applies different authentication methods based on the specific characteristics and location requirements of each network node. Satellite geolocation is used for nodes requiring high security, while network ping ranging is used for nodes where satellite authentication is unavailable or unnecessary, creating a tailored authentication approach that balances security with system complexity

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements selective authentication where not all network nodes require satellite geolocation authentication. Instead, authentication is applied partially to nodes based on security requirements and availability, reducing overall system complexity while maintaining security for critical nodes

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If encrypted tunneling is used for unverifiable nodes, then data security is improved, but transmission overhead and processing time increase

Engineering Contradiction:
Improvedata transmission securityVSAvoidtransmission delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Encrypted tunneling is applied selectively only to packets routing through unverifiable nodes, while packets through authenticated nodes use standard routing without additional encryption overhead. This partial application minimizes transmission delay for the majority of traffic while maintaining security for sensitive communications

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A system, method, and apparatus for secure routing based on the physical location of routers are disclosed herein. The disclosed method for secure data transmission of at least one data packet through a plurality of network nodes involves defining a source network node, a destination network node, and at least one security constraint, which is based on the physical location of at least one of the network nodes. The method further involves comparing available network nodes with the security constraint(s) to determine which of the available network nodes meet the security constraint(s) and, thus, are qualified network nodes. Additionally, the method involves determining a route comprising at least one of the qualified network nodes to route the data packet(s) through from the source network node to the destination network node. Further, the method involves transmitting the data packet(s) through the route of the qualified network node(s).
