Secure Portal Device for Home Network Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Virtual Private Networks (VPNs) are costly, difficult to set up and maintain, and incur performance overhead due to encryption requirements, leading to slower internet connectivity and difficulties in accessing local resources when used for remote access to home networks.
Innovation Solution
A secure portal device paired with a home router that establishes a direct and encrypted VPN connection, using a processor and wireless radio to extend the home network securely and conveniently, operating as a local access point to provide level 2 access and reduce bandwidth overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional VPN service is used for remote network access, then security and encrypted connection are improved, but cost and setup complexity increase
Solution Approach 1:
The portal device automatically performs VPN connection establishment, authentication, and network configuration without requiring manual setup by the user. The device self-configures the encrypted tunnel connection to the home network, eliminating complex setup procedures while maintaining security.
Solution Approach 2:
The patent introduces a portal device as an intermediary component between the remote user and the home network. This portal device simplifies the interaction by handling all VPN protocol complexities, authentication mechanisms, and encryption/decryption operations, making the system easy to use while maintaining strong security.
2Reliability
If encryption protocols are implemented for secure VPN connection, then security is improved, but bandwidth and performance deteriorate
Solution Approach 1:
The patent implements encryption selectively for only the control and authentication traffic between the portal device and home network, rather than encrypting all data traffic. This localized approach to encryption maintains security for critical communications while minimizing the bandwidth overhead impact on overall network performance.
3Area of stationary object
If VPN is run from router for whole-house solution, then network coverage is improved, but access to local resources becomes more difficult
Solution Approach 1:
The patent segments the network architecture by introducing a portal device that operates independently from the main home router. The portal device creates a localized encrypted access point that users can connect to, while the home network continues to operate normally. This segmentation allows users to access local resources directly through the portal device without interfering with the main network's resource sharing mechanisms.
