Wireless Display Authentication via Distributed Key Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display systems for conferences face security issues due to the risk of unauthorized access and data theft when using wireless connections, as encryption keys can be mismanaged or intercepted, and authentication methods lack robust protection against malicious third parties.
Innovation Solution
An information output apparatus and method that produces and securely distributes key information for authentication, using units for producing, outputting, and receiving authentication information, ensuring only authorized communication devices can access and display presentation data, employing cryptographic systems like Public Key or Common Key Cryptosystems to verify authentication and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless connection is used to connect communication apparatus to information output apparatus, then ease of operation and positioning flexibility are improved, but security and reliability deteriorate due to risk of unauthorized access and data theft
Solution Approach 1:
The system performs preliminary authentication by verifying authentication information (such as passwords or certificates) before allowing wireless connection and data transmission. This preliminary security check ensures that only authorized communication apparatus can connect to the information output apparatus, preventing unauthorized access while maintaining wireless convenience
Solution Approach 2:
The invention introduces an authentication information verification mechanism as an intermediary between the communication apparatus and information output apparatus. This intermediary layer validates authentication information and controls the establishment of wireless connections, thereby securing the wireless communication channel without compromising operational ease
2Adaptability or versatility
If encryption keys are distributed in advance to authorized participants, then authentication capability is improved, but security deteriorates due to risk of key leakage and unauthorized access
Solution Approach 1:
The system distributes authentication information (such as passwords or certificates) in advance to authorized participants before the actual authentication event. This preliminary distribution enables participants to be prepared for authentication without exposing sensitive encryption keys, as the authentication information can be securely stored and used without revealing underlying cryptographic secrets
Solution Approach 2:
The invention uses authentication information that can be securely distributed and consumed without exposing long-term secrets. The authentication information acts as a disposable credential that can be verified without revealing the underlying authentication mechanism or long-term keys, thereby maintaining security while enabling authentication
3Ease of operation
If discrimination information is transmitted without encryption to prevent accidental interference, then ease of operation is improved, but security deteriorates due to risk of information theft by unauthorized third parties
Solution Approach 1:
The system performs preliminary authentication by verifying authentication information before allowing communication apparatus to access the information output apparatus. This preliminary verification ensures that even if discrimination information is transmitted in plain text, only authenticated participants can receive and use this information, preventing unauthorized theft while maintaining operational simplicity
Data Source
AI summary
An apparatus for displaying information received from a communication apparatus including a key information producing unit configured to produce key information used to authenticate the communication apparatus; a key information distributing unit configured to distribute the key information; an authentication information receiving unit configured to receive authentication information; an authenticating unit configured to authenticate the communication apparatus by verifying whether or not the authentication information was formed based upon the key information; and a display information receiving unit configured to receive display information from the authenticated communication apparatus, wherein the authenticated communication apparatus has a distribution range during reception of the key information such that the outputted key information can be acquired.
