Home Gateway Authentication via Coding Decoding Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home network systems lack authentication processes for new devices, leading to potential exposure and security risks as they can be accidentally or intentionally connected to adjacent networks, compromising privacy and security.
Innovation Solution
A home device authentication system that includes a home gateway with input/output, device process, and application process units to authenticate devices using coding and decoding information, with user approval and storage for secure network settings, and a method to request decoding information from a service provider if needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no authentication process is implemented for new devices, then device connection speed and ease of connection are improved, but network security and privacy are worsened
Solution Approach 1:
The system performs preliminary authentication actions before allowing device connection. The home gateway authenticates new devices by verifying coding information and obtaining decoding information from service providers before the devices can access the network, preventing unauthorized connections while maintaining ease of use for authorized devices
Solution Approach 2:
The patent introduces an intermediary authentication mechanism between devices and the network. The home gateway acts as a mediator that verifies device credentials through coding/decoding information exchange with service providers, creating a security layer without requiring direct user intervention for each connection
2Object-affected harmful factors
If authentication process is added for new devices, then network security is improved, but device connection complexity and user operation difficulty are worsened
Solution Approach 1:
The authentication system operates autonomously without requiring user involvement. The home gateway automatically performs authentication by exchanging coding information with devices and obtaining decoding information from service providers, handling the complex verification process behind the scenes while presenting simple network access to users
Solution Approach 2:
The patent merges multiple authentication functions into a single integrated process at the home gateway. The gateway combines device verification, coding information validation, and service provider coordination into one unified authentication mechanism, simplifying the overall system architecture while maintaining security
3Device complexity
If unilateral authentication structure is used where only home gateway authenticates devices, then system simplicity is improved, but network exposure risk to adjacent networks is worsened
Solution Approach 1:
The authentication system incorporates feedback mechanisms where the home gateway receives and verifies coding information from devices, then obtains decoding information from service providers to validate authenticity. This feedback loop ensures that only authorized devices can access the network while maintaining structural simplicity
Solution Approach 2:
The system performs preliminary authentication verification before allowing any network communication. By verifying coding information and obtaining decoding information from service providers in advance, the system prevents unauthorized devices from establishing connections or exposing the network to adjacent networks
Data Source
AI summary
A home device authentication system and method, wherein the home device authentication system includes one or more home devices each having device information including coding information for authentication and information on a service provider providing authentication services; and a home gateway including decoding information corresponding to the coding information of the home devices, and for authenticating the home devices by using the decoding information. Further, if there exists no decoding information in the home gateway, the home gateway requests the decoding information from the service provider. Accordingly, privacy and security for the home network is secured.
