Wireless Terminal Authentication Control for Ad Hoc Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially in ad hoc mode, users face difficulties in setting up secure and exclusive data communication with specific devices due to the need for complex network setup and the risk of unnecessary data communication with multiple devices, leading to resource, security, and privacy issues.
Innovation Solution
A wireless communication terminal equipped with a recognition unit, authentication unit, communication unit, selection unit, and authentication control unit that allows users to select and authenticate only specific devices for data communication, using protocols like WPS to manage network settings and prevent unauthorized connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless communication terminal performs authentication processing with all existing wireless communication terminals in an ad hoc network, then data communication can be established with any terminal, but unnecessary data communication and security risks increase
Solution Approach 1:
The patent segments the authentication process by introducing a selected terminal list that divides all wireless communication terminals into two groups: selected terminals (for authentication) and non-selected terminals (for rejection). This segmentation allows the system to maintain authentication capability with specific terminals while preventing unnecessary authentication attempts with others, thereby reducing security risks and resource consumption.
Solution Approach 2:
The patent applies local quality by making the authentication behavior terminal-specific rather than uniform. Each terminal in the selected list receives authentication treatment, while terminals outside the list are automatically rejected. This creates different authentication qualities for different terminals based on their presence in the selected list, enabling secure and efficient communication only with intended partners.
2Reliability
If complex network setting information is manually configured in the wireless communication terminal, then secure and exclusive data communication can be established, but the ease of operation decreases
Solution Approach 1:
The patent implements self-service by enabling the wireless communication terminal to automatically manage the selected terminal list and authentication process without manual configuration. The terminal autonomously determines which terminals to authenticate with based on pre-stored selection criteria or user-friendly interfaces, eliminating the need for users to manually configure complex network settings while maintaining secure and exclusive communication.
Solution Approach 2:
The patent applies preliminary action by pre-storing selected terminal information in the wireless communication terminal before actual data communication occurs. This preliminary preparation of the selected terminal list allows the terminal to automatically perform authentication with the correct terminals without requiring users to manually configure settings at the time of use, thus simplifying operation while ensuring security.
3Ease of operation
If the wireless communication terminal automatically performs authentication with all detected terminals, then network participation is simplified, but resource consumption and security exposure increase
Solution Approach 1:
The patent segments the set of detected wireless communication terminals into selected terminals (for authentication) and non-selected terminals (for rejection) based on pre-stored information. This segmentation enables the terminal to automatically participate in the network while limiting authentication attempts to only the selected terminals, thereby reducing energy consumption and avoiding unnecessary resource expenditure on terminals that should not be communicated with.

AI summary
A wireless communication terminal may include a recognition unit that recognizes terminals that are located in its own vicinity and that are capable of performing wireless communication, an authentication unit that performs authentication at a data link level for the recognized terminals that are capable of performing wireless communication, a communication unit that receives authentication requests from the recognized terminals that are capable of performing wireless communication, and performs data communication with the recognized terminals, a selection unit that selects any one of the recognized terminals that are capable of performing wireless communication, and an authentication control unit that, if the authentication request is received from a terminal that has not been recognized, causes the authentication unit to perform the authentication for the selected terminal, and at the same time prohibits the authentication unit from performing the authentication for terminals other than the selected terminal.
