Linking Server Mediator for Secure P2P Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote surveillance and control technologies using Power Line Communication (PLC) require complex IP and domain name management, making them vulnerable to hacker attacks and difficult to scale, as devices need fixed IPs and users must manually manage IP changes.
Innovation Solution
A communication system that establishes Point-to-Point (P2P) connections using a linking server and administration server, allowing devices to connect without revealing IP addresses or domain names, with the administration server managing linking server registrations and load balancing, enabling secure and scalable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PLC technology with fixed IP addresses is used for remote device communication, then devices can be connected and controlled, but the system becomes vulnerable to hacker attacks and requires manual IP management
Solution Approach 1:
The patent introduces a linking server as an intermediary between remote devices and client devices. The linking server manages connection information and enables P2P communication without exposing actual IP addresses. This mediator architecture allows devices to communicate securely while the server handles the complexity of connection management, eliminating the need for fixed IPs and manual IP updates.
2Stability of the object's composition
If devices use fixed IP addresses for stable connections, then connection reliability is improved, but scaling the system requires manual IP updates and increases operational complexity
Solution Approach 1:
The patent implements a dynamic connection management system where the linking server maintains real-time connection information and dynamically routes communications. Instead of static IP assignments, the system uses dynamic connection establishment where the server provides current connection details to both parties. This allows the system to scale efficiently as devices are added or removed, while maintaining stable connections through the server's dynamic coordination.
3Ease of operation
If IP addresses and domain names are exposed for direct device access, then connection establishment is simplified, but the system becomes susceptible to hacker sniffing and attacks
Solution Approach 1:
The linking server acts as a privacy-protecting intermediary that shields actual device IP addresses and domain names from direct exposure. When a client device wants to connect to a remote device, it requests connection information from the linking server, which provides anonymized or temporary connection details. This maintains ease of connection establishment while protecting against hacker sniffing and attacks on exposed network identifiers.
4Ease of operation
If manual IP management is implemented for device connections, then connection control is precise, but operational complexity increases and user burden grows
Solution Approach 1:
The linking server implements self-service connection management by automatically tracking device connections, generating connection information, and providing it to relevant parties without human intervention. When devices are added, removed, or move networks, the server automatically updates its records and provides current connection details to maintaining stable connections. This eliminates the need for users to manually manage IPs, saving time and reducing operational complexity.

AI summary
A communication system for establishing a P2P connection is disclosed, wherein the communication system comprises: a networked device or service device having an identification; a linking server for providing connecting information to enable a terminal device or client device to establish a P2P connections between the service device and the client device, wherein the identification of service device is registered in the linking server, wherein the client device communicates with the link server to establish a P2P connection to the service device according to the connecting information provided by the linking server, wherein the client device has not been registered into the linking server when the P2P is established. In addition, A UID (Unique Identification) can be embedded in a processor, wherein the UID can be stored in a non-volatile memory device inside the processor and the UID will be programmed and tested after the processor is fabricated, so that it can be readily used for establishing A P2P connection.
