Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not provide detailed methods for establishing wireless connections between devices using IP addresses beyond wired communication authentication.
Innovation Solution
A computer program for a terminal device that sends IP address and public key to a communication device via a shared network, enabling authentication and connection establishment through a series of steps involving address and key exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication authentication using IP address is implemented, then authentication reliability is improved, but wireless connection establishment capability deteriorates
Solution Approach 1:
The patent segments the authentication and connection establishment process into distinct phases: wired authentication phase (using IP address for reliability) and wireless connection phase (using MAC address for adaptability). This allows each phase to use the most appropriate communication method for its specific requirements.
Solution Approach 2:
The terminal device acts as an intermediary that bridges wired and wireless communication domains. It performs authentication via wired connection using IP address, then uses the authenticated session to establish wireless connections, thereby transferring the benefits of reliable wired authentication to wireless connectivity.
2Measurement precision
If detailed authentication methods for wired communication are specified, then authentication precision is improved, but documentation completeness for wireless communication deteriorates
Solution Approach 1:
The patent creates a universal authentication framework that works across both wired and wireless communication modes. The same authentication protocol and message formats are used regardless of whether the underlying transport is wired or wireless, eliminating the need for separate detailed specifications.
Solution Approach 2:
Instead of specifying different authentication methods for wired and wireless communications, the patent inverts the approach by specifying a unified authentication method that can operate over either communication type. The communication type becomes a parameter of the transport layer rather than determining the authentication layer behavior.

AI summary
A first terminal device may send address information which is an IP address of the first terminal device to the first communication device by using a communication network, and send a public key of the first terminal device to the first communication device by using the communication network. The first terminal device may receive a first authentication request in which the first public key is used from the first communication device by using the communication network. The first authentication request may be sent with the address information as a destination. The terminal device may send a first authentication response to the first communication device by using the communication network and send connection information to the first communication device by using the communication network. The connection information may be used by the first communication device to establish a first wireless connection between the first communication device and an external device.
