Device Authentication Control Using Battery and Link Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication technologies between devices often result in unnecessary authentication processes, leading to power wastage due to insufficient information transmission and poor communication conditions, such as low battery levels or poor signal quality in portable devices.
Innovation Solution
A control device and method that perform authentication only when predetermined conditions are met, such as the presence of necessary communication functions and sufficient battery charge, by using information obtained through communication to determine if the authentication process should be executed, thereby preventing unnecessary authentication and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is performed between devices, then security and device verification are improved, but power consumption increases and unnecessary authentication may occur
Solution Approach 1:
The control device performs preliminary checks of communication conditions (signal quality, battery level, communication function presence) before initiating the authentication process. This preliminary action prevents unnecessary authentication attempts that would waste power, while still ensuring security by verifying conditions are suitable for authentication when it does occur.
2Reliability
If authentication process is performed between devices, then device verification is improved, but communication time increases
Solution Approach 1:
The control device evaluates communication conditions (signal quality, battery level, communication function presence) before initiating authentication. This preliminary assessment prevents time-wasting authentication attempts when conditions are poor, reducing overall communication time while maintaining verification reliability when authentication is actually performed.

AI summary
A control device and control method prevent an unnecessary authentication process from being executed. The control device includes a control section configured to perform an authentication process of authenticating another device by using information obtained through communication with the other device. In the case where a predetermined condition is satisfied, the control section performs control in such a manner that the authentication process is not performed.
