Communication System Authentication Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when registering multiple apparatuses with a mobile device as the registration process needs to be performed manually for each device, leading to increased effort and time.
Innovation Solution
A communication system where one apparatus performs registration processing and shares the obtained authentication information with other apparatuses, reducing the need for individual registration on each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If registration processing is performed individually for each apparatus, then authentication security is maintained, but user operation complexity increases and registration time is extended
Solution Approach 1:
The patent merges the registration operations across multiple apparatuses by enabling one apparatus to perform registration that automatically applies to other apparatuses. The mobile terminal performs single registration processing, and the system combines this authentication information across multiple apparatuses through information sharing, eliminating the need for separate registration at each device while maintaining security.
Solution Approach 2:
The patent introduces a server as an intermediary that facilitates information sharing between apparatuses. The server receives authentication information from the mobile terminal during registration and distributes it to multiple apparatuses, acting as a mediator that enables single registration to validate multiple devices without compromising security.
2Reliability
If registration processing is performed individually for each apparatus, then device-specific authentication is ensured, but registration time increases
Solution Approach 1:
The patent implements preliminary action by performing registration processing at a central point (mobile terminal or server) before the user needs to access multiple apparatuses. The authentication information is obtained and shared in advance, so when the user approaches any apparatus, the authentication is already established, eliminating repeated registration time.
Solution Approach 2:
The patent combines the registration process into a single operation performed by the mobile terminal, which then shares the authentication information across multiple apparatuses. This merging reduces the total registration time from multiple separate operations to one unified registration process.
3Ease of operation
If authentication information is shared among multiple apparatuses, then user convenience is improved, but system complexity increases
Solution Approach 1:
The patent uses a server as an intermediary to manage the complexity of information sharing. Instead of creating complex direct communication channels between multiple apparatuses, the server centralizes the authentication information storage and distribution, simplifying the system architecture while enabling convenient cross-device authentication.

AI summary
A communication system includes a plurality of apparatuses each performing wireless communication with a mobile apparatus. Each of the plurality of apparatuses performs authentication processing for determining whether the mobile apparatus is a mobile apparatus registered beforehand. At least one apparatus of the plurality of apparatuses performs registration processing for obtaining mobile key information to be used for the authentication processing from the mobile apparatus and registering the mobile key information, and sharing processing for transmitting the mobile key information obtained by the registration processing to the other apparatus.
