Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-device authentication methods lack certainty and security, particularly when the authentication process is repeated multiple times, leading to potential gaps in signal recognition and reduced accuracy in distance calculation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the authentication process is repeated more than once to improve certainty, then authentication reliability is improved, but the risk of signal misrecognition and authentication failure increases
Solution Approach 1:
The system performs preliminary actions by preparing multiple authentication processes in advance and executing them sequentially. The control device is configured to repeat the authentication process multiple times before making a final determination, allowing it to gather sufficient evidence for reliable authentication while maintaining signal recognition accuracy through consistent methodology across repetitions.
Solution Approach 2:
The system incorporates feedback mechanisms where each authentication process result is fed back into the decision-making process. The control device evaluates outcomes from multiple authentication attempts and uses this feedback to determine whether authentication should be approved or rejected, improving overall reliability while maintaining precision through systematic evaluation.
2Reliability
If the authentication process is repeated more than once to improve certainty, then authentication reliability is improved, but security may be compromised due to potential gaps in signal recognition
Solution Approach 1:
The control device is pre-configured with the authority and methodology to execute multiple authentication processes before making a final decision. This preliminary setup ensures that security protocols are consistently applied across all authentication attempts, preventing security gaps that might occur with ad-hoc authentication methods.
Solution Approach 2:
The system uses feedback from each authentication attempt to inform subsequent decisions. By systematically evaluating results from multiple authentication processes and using this feedback to determine final authentication outcomes, the system improves reliability while maintaining security through consistent, rule-based decision-making that prevents arbitrary security compromises.
3Object-affected harmful factors
If authentication information is changed for each process group, then security is improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into multiple process groups, where each group uses distinct authentication information. This segmentation allows the system to enhance security by ensuring that compromise of authentication information in one group does not affect other groups, while the modular structure manages complexity through organized separation of authentication processes.
Solution Approach 2:
The system changes authentication information parameters for each process group, using different credentials or verification data across separate authentication sequences. This parameter variation strengthens security by preventing replay attacks and information leakage, while the systematic management of parameter changes keeps device complexity controllable through structured implementation.
Data Source
AI summary
A control device controls an authentication process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device. The control device performs the control in such a manner that authentication information is changed for each process group in which the authentication process is repeated more than once. Signals transmitted or received in the authentication process include a trigger signal, a request signal, and a response signal. The control device executes the process group in which the authentication process is repeated more than once for the trigger signal, the request signal, and the response signal, and changes the authentication information to be used for each of the trigger signal, the request signal, and the response signal each time the process group is executed.
