Wi-Fi Direct User Equipment Automatic Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in initiating wireless communication between devices using Wi-Fi Direct, as they need to perform authentication processing with parent equipment, which is challenging if they are unaware of the parent equipment's location.
Innovation Solution
User equipment is designed with detection, notification, and communication modules to automatically detect nearby devices, perform authentication, and establish wireless communication without requiring user-operated authentication on the parent equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic detection and authentication is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The child equipment automatically performs detection and authentication of other child equipment without requiring user intervention. The system serves itself by having the child equipment independently identify and authenticate peer devices, eliminating the need for manual user operations while managing the complexity within the device's automated protocols
Solution Approach 2:
The child equipment performs preliminary authentication with the parent equipment before attempting to communicate with other child equipment. This preliminary action establishes the necessary credentials and permissions in advance, allowing subsequent automatic authentication with peer devices to proceed smoothly without user involvement
2Productivity
If authentication processing is automated, then productivity is improved, but reliability may worsen due to security concerns
Solution Approach 1:
Authentication with the parent equipment is performed in advance before peer-to-peer communication begins. This preliminary authentication establishes secure credentials and permissions that are then reused for automatic authentication with other child equipment, enabling rapid productivity improvement while maintaining security through the pre-established trusted relationship
Solution Approach 2:
The parent equipment serves as an intermediary that vouches for the authenticity of child equipment. When one child equipment needs to authenticate with another, the parent equipment's prior authentication acts as a mediator, allowing the system to maintain high reliability through trusted intermediation while achieving fast automatic authentication

AI summary
The present disclosure relates to user equipment for, a communication method of, a program for, and a communication system for starting wireless communication among pieces of user equipment without placing operational load on a user. In the communication system according to the present disclosure, child equipment includes a detection module that detects different user equipment and performs authentication processing with the different user equipment that is detected, a notification module that notifies the parent equipment of identification information indicating the different user equipment that has been authenticated, and a communication module that performs the wireless communication with the different user equipment that is caused to belong to the group that is managed by the parent equipment, and the parent equipment includes an obtainment module that obtains the identification information which is notified from the child equipment, and an authentication module that, if there is a connection request from different user equipment that does not belong to the group, authenticates connection of the different user equipment that does not belong to the group, based on the identification information that is notified from the child equipment. The present disclosure, for example, can be applied to the user equipment that performs the wireless communication according to Wi-Fi Direct.
