Mesh Network Authentication Using Asymmetric Keys Across Router Brands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mesh network security mechanisms are inadequate, particularly in environments requiring high security, due to risks associated with hardware incompatibility between different router brands and the lack of effective security measures to ensure secure connections.
Innovation Solution
The implementation of an asymmetric cryptography mechanism in the connection establishing system for mesh networks, where transceivers use secure connection request and response signals with public and private keys to authenticate and authorize devices, ensuring only specific access points can establish secure online connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asymmetric cryptography mechanism is implemented for secure connection, then network security is improved, but device complexity increases
Solution Approach 1:
Public keys are pre-configured in access points and client devices before connection establishment. This preliminary action eliminates the need for complex real-time key generation and exchange, reducing connection complexity while maintaining security. The pre-provisioned keys enable immediate secure authentication without additional setup steps.
Solution Approach 2:
The patent uses public key copies distributed to multiple devices instead of sharing secret keys. Each device holds a copy of the other's public key, enabling mutual authentication without complex key management. This copying approach simplifies the security mechanism while ensuring reliable secure connections.
2Reliability
If hardware-specific security mechanisms are used, then connection security is improved, but adaptability between different router brands deteriorates
Solution Approach 1:
The patent implements a universal asymmetric cryptography-based authentication mechanism that works across different router brands and hardware platforms. By using standardized public key infrastructure instead of hardware-specific security protocols, the system achieves both high security and broad interoperability, allowing any device with the appropriate key to establish secure connections.

AI summary
A connection establishing system and method for a mesh network is provided, the mesh network includes a first transceiver and a second transceiver, the method includes performing a secure connection procedure including: transmitting, by the second transceiver, a secure connection request signal including a identifier to the first transceiver. The first transceiver encrypts the authentication message by using a public key corresponding to the identifier to generate a secure connection response signal and transmit the same to the second transceiver, the second transceiver decrypts the secure connection response signal by a private key to generate a decryption message and transmits an association request signal including the decryption message to the first transceiver. The first transceiver receives the association request signal, and determines whether the decryption message matches with the authentication message; if so, the first transceiver is allowed to establish a secure connection with the second transceiver.
