Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Apparatuses that form wireless networks often lack an imaging function, making it difficult to share encryption information for secure communication parameter settings, as existing methods require imaging to decode and share encryption keys.
Innovation Solution
A communication apparatus that operates as an access point, providing and receiving communication parameters, including encryption methods and authentication methods, using captured image-based encryption information, allowing secure encrypted communication without the need for an imaging function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an imaging function is added to network-forming apparatuses to enable sharing of encryption information through code imaging, then security of communication parameters is improved, but device complexity increases
Solution Approach 1:
A mobile terminal is introduced as an intermediary device that performs the imaging function to capture code information from the network-forming apparatus. This mediator enables secure sharing of encryption information without requiring the network-forming apparatus itself to have imaging capabilities, thus maintaining security while avoiding increased device complexity at the network-forming end.
Solution Approach 2:
The imaging function is segmented from the network-forming apparatus and assigned to a separate mobile terminal. This segmentation allows the network-forming apparatus to remain simple while still enabling secure parameter sharing through the coordinated action of the mobile terminal capturing and processing the code information.
2Reliability
If code information including public key is used to share encrypted communication parameters, then security during parameter exchange is improved, but ease of operation deteriorates when apparatus lacks imaging function
Solution Approach 1:
The mobile terminal serves as an intermediary that handles the complex imaging and code decoding operations. The network-forming apparatus simply needs to display the code information, while the mobile terminal captures and processes it, maintaining both security through encrypted parameter exchange and ease of operation by eliminating the need for imaging functionality in the network-forming apparatus.
3Reliability
If imaging function is required for sharing encryption information, then encryption information can be shared securely, but adaptability of apparatus decreases
Solution Approach 1:
By introducing a mobile terminal as an intermediary, the system achieves both secure encryption information sharing and enhanced adaptability. The network-forming apparatus can be any device without imaging capabilities (printers, servers, etc.), while the mobile terminal provides the necessary imaging and code processing functions, making the system versatile across different apparatus types.

AI summary
A communication apparatus receives information encrypted based on encryption information obtained by capturing an image of code information about the communication information from a different communication apparatus operating as an access point to form a wireless network. The communication apparatus and the different communication apparatus perform encrypted communication based on the information.
