IoT Cross-Connect Token Handshake for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Things (IoT) network, securing data transmission is challenging due to the difficulty in detecting compromised IoT devices, which can lead to compromised communications, especially since these devices are often interconnected and lack central control, making it hard to ensure secure data paths.
Innovation Solution
A method utilizing cross-connect tokens, which are hardware or software constructs that enable secure communication between devices, involves generating and validating one-time security codes across multiple tokens to verify the security of communication paths before data transmission, ensuring that only authorized connections are established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT devices are interconnected without central control to enable flexible communication, then adaptability and ease of operation are improved, but security and reliability deteriorate because compromised devices can transmit malicious communications
Solution Approach 1:
The system performs preliminary security validation by generating and verifying one-time security codes through cross-connect tokens before establishing any data transmission path. This advance security check ensures that even in a decentralized IoT environment, communication paths are pre-validated for security, preventing compromised devices from establishing malicious connections.
Solution Approach 2:
Cross-connect tokens act as intermediary security validators between IoT devices. These tokens generate and verify one-time security codes, serving as a mediating layer that authenticates communication paths without requiring central control. This intermediary mechanism maintains security while preserving the decentralized, flexible nature of IoT communications.
2Ease of operation
If traditional security validation methods are used in IoT networks, then ease of operation is maintained, but security deteriorates because compromised devices can still transmit malicious communications
Solution Approach 1:
Cross-connect tokens autonomously generate and validate one-time security codes without requiring manual intervention or complex security configurations. Each token independently performs security validation, making the system both secure and easy to operate. The self-service nature of token validation eliminates the need for centralized security management while maintaining operational simplicity.
3Productivity
If communication paths are established without validation to improve transmission speed, then productivity is improved, but security deteriorates because unauthorized access cannot be prevented
Solution Approach 1:
Security validation through one-time code verification is performed preliminarily and in parallel during the connection establishment phase, rather than sequentially after path selection. This allows security checks to occur without significantly impacting data transmission speed, maintaining both productivity and security.

AI summary
Methods for securing data transmission are provided. Methods include utilizing a plurality of cross-connect tokens. Methods include receiving a communication line validation communication at a source device. Methods include powering a first passive cross-connect token located at the source device. The first passive cross-connect token may draw power from the communication. The first token may generate a first OTSC (“onetime security code”). The first token may transmit the first OTSC to a second token. The first OTSC may power the second token. The second token may validate the first OTSC, and generate a second OTSC. The second token may transmit the second OTSC to a third token. The third token may be located on a target device. The second OTSC may power the third token. The third token may validate the second OTSC, and transmit, upon validation, a communication line validated communication to the source device.
