SWAP Signaling Server for Secure WebRTC Session Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in ensuring secure and efficient establishment of Web Real-Time Communication (WebRTC) sessions between endpoint computing devices, particularly in preventing unauthorized connections and mitigating security threats like DDoS and man-in-the-middle attacks.
Innovation Solution
Implementing a Simple WebRTC Application Protocol (SWAP) server that acts as a signaling server, using a shared secret key for authentication and encryption, and a Message Authentication Code (MAC) to authenticate messages, while enabling endpoint computing devices to verify each other's identity before establishing a session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a signaling server is implemented to establish WebRTC sessions between endpoint computing devices, then session establishment efficiency is improved, but security risks increase due to potential unauthorized connections and attacks
Solution Approach 1:
The patent introduces a signaling server as an intermediary that mediates all communication between endpoint computing devices. The server receives session requests, verifies matching criteria, and forwards requests only after validation. This intermediary role enables efficient session establishment while maintaining security through centralized control and verification of connection requests.
2Reliability
If matching criteria verification is implemented for all session requests, then connection security is improved, but processing complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring matching criteria for each endpoint computing device before session establishment attempts. The signaling server stores these criteria in advance, allowing rapid verification when session requests arrive. This pre-preparation reduces real-time processing complexity while maintaining rigorous security checks.
3Speed
If the signaling server forwards all verified session requests, then session establishment speed is improved, but exposure to attacks increases
Solution Approach 1:
The patent applies preliminary anti-action by implementing security measures before forwarding session requests. The signaling server verifies matching criteria and validates session requests against predefined security policies before any forwarding occurs. This preemptive security approach enables fast session establishment while blocking malicious requests before they can reach endpoint devices.
