Dynamic Authentication for Multi-Application Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle to specify the correct application to start when multiple applications correspond to a single protocol, leading to ambiguity in data transmission.
Innovation Solution
A communication device and system that dynamically changes authentication information based on the type of data selected, allowing it to select a suitable protocol and transmit this information to another device to initiate the appropriate application, even if multiple applications are available for the protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If protocol designation is used to specify the application to be started, then the application can be specified when there is only one application corresponding to the protocol, but the application cannot be specified when there are multiple applications corresponding to the protocol
Solution Approach 1:
The patent changes the authentication information parameter dynamically based on the type of data selected on the application. By modifying the authentication information to include data type information, the system enables the receiving device to distinguish between different applications that support the same protocol, thus resolving the ambiguity in application specification while maintaining multi-application support
2Reliability
If authentication information is dynamically changed according to data type, then the correct application can be specified even when multiple applications correspond to the protocol, but the complexity of the authentication system increases
Solution Approach 1:
The patent makes the authentication information serve multiple functions: it not only performs mutual authentication between devices but also conveys the type of data selected on the application. This multi-functionality allows the system to specify the correct application without adding separate signaling mechanisms, thereby improving reliability while limiting the increase in system complexity
