Secure D2D Communication via Cellular Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device-to-device communication methods over public Internet face security vulnerabilities and challenges in network topology, firewall restrictions, and device mobility, especially for IoT devices, which can lead to breaches and impact multiple connected devices.
Innovation Solution
A system and method for secure device-to-device data communication using a Device Management Server and Security Enforcement Server on distributed cloud servers, establishing secure tunnels without public Internet connection, with anomaly detection and alert mechanisms, utilizing blockchain digital ledger for ownership and security policies, and employing IPSec, SSL, or TLS VPN for encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device-to-device communication is established over public Internet, then remote access and direct communication are enabled, but security vulnerabilities and firewall restrictions increase
Solution Approach 1:
The patent introduces a cellular network as an intermediary communication path between devices. Instead of direct Internet connectivity, devices establish connections through cellular network infrastructure, which acts as a trusted mediator providing inherent security and bypassing public Internet firewall restrictions while enabling remote access
2Adaptability or versatility
If IoT devices connect via home Wi-Fi network, then local device communication is simplified, but security breach impact spreads to multiple devices
Solution Approach 1:
The patent segments the communication architecture by assigning each device its own cellular network connection independent of local Wi-Fi networks. This segmentation isolates devices from each other at the network level, so that a security breach on one device cannot propagate to other devices through the same local network
3Object-affected harmful factors
If secure tunnels are established through cellular network, then security and firewall restrictions are mitigated, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent leverages the cellular network's inherent capabilities and existing infrastructure to provide secure communication. The cellular network itself provides the tunneling and security functions without requiring complex additional infrastructure at the device level, as the network operator's infrastructure handles the complexity
