Router Security Information Transmission via Local Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for acquiring router security information, such as Wi-Fi passwords, involve transmitting data through a cloud server, making it vulnerable to privacy leaks and unauthorized access when the server is compromised or user accounts are hacked.
Innovation Solution
Establishing a local area network for transmitting encrypted router security information directly between the router and the terminal device, using authentication tokens and encryption keys to ensure secure access and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If router security information is transmitted through a cloud server, then the information can be accessed remotely, but the security risk increases due to potential server compromise or account hacking
Solution Approach 1:
The patent extracts the security information transmission from the cloud server environment and relocates it to a direct peer-to-peer connection between the router and terminal device. This removes the vulnerable intermediate server node from the communication path, eliminating the security risks associated with server compromise while maintaining remote access capability through direct encrypted channels.
Solution Approach 2:
The patent introduces QR codes and encrypted communication protocols as intermediaries to enable secure direct connection between router and terminal device without requiring cloud server mediation. The QR code serves as a secure handshake mechanism that establishes an encrypted peer-to-peer channel, replacing the vulnerable cloud-based authentication process.
2Adaptability or versatility
If a cloud server is used to manage router security information, then centralized control is achieved, but vulnerability to remote attacks increases
Solution Approach 1:
The patent segments the centralized cloud-based security management system into distributed peer-to-peer connections. Each router- terminal device pair establishes an independent encrypted communication channel, eliminating the single point of failure represented by the cloud server while maintaining centralized control capabilities through direct device-to-device authentication and key management.
3Loss of information
If router security information is stored centrally on a server, then data accessibility is improved, but privacy leakage risk increases when the server is compromised
Solution Approach 1:
The patent extracts security information storage from centralized server repositories and places it locally within individual router and terminal device secure memory. This distribution of stored credentials eliminates the vulnerability of centralized data stores while maintaining accessibility through direct peer-to-peer retrieval during authentication processes.

AI summary
The present disclosure relates to a method and apparatus for transmitting router security information, relating to the technical field of router security. The present disclosure provides a method for transmitting router security information, which is applied in a router, comprising steps of: transmitting, to a terminal requesting to acquire router security information, a generated link of a local area network for transmitting the router security information; receiving an access request initiated by the terminal through a network address to which the link of the local area network is pointed; and, returning, through the local area network, a response to the access request to the terminal, the response containing encrypted router security information. In the technical solutions of the present disclosure, the encrypted router security information is transmitted by a local network established for transmitting security information by a router. In this security information transmission mode, the possibility of remotely acquiring router security information is eliminated. Moreover, the situation where the router security information is transmitted on the cloud is also avoided, and the security of privacy information of terminal devices is improved.
