Wireless Power Reception Authentication to Limit Unnecessary Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless power transmission systems, authentication processing between power transmitting and receiving apparatuses can lead to unnecessary processing when the validity of the target apparatus is not recognized, resulting in inefficiencies and potential issues like excessive heat generation.
Innovation Solution
A power receiving apparatus is designed with an authentication unit and a control unit that determines the content related to power reception based on the result of device authentication, allowing for the control of whether to perform subsequent authentication, thereby reducing unnecessary processing by limiting power transmission if initial authentication fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mutual authentication processing is performed between power transmitting and receiving apparatuses to enhance security, then authentication security is improved, but processing time increases and unnecessary processing occurs when the validity of the target apparatus is not recognized
Solution Approach 1:
The patent applies preliminary action by performing a first authentication (e.g., based on device identifiers) before the second authentication (e.g., based on cryptographic verification). This preliminary check allows the system to quickly determine whether the target apparatus is valid, avoiding unnecessary execution of the more time-consuming second authentication when the first authentication fails, thus reducing overall processing time while maintaining security
2Reliability
If multiple authentication protocols are executed to ensure secure power transmission, then authentication security is improved, but system complexity increases
Solution Approach 1:
The patent segments the authentication process into two distinct phases: a first authentication protocol (simpler, faster) and a second authentication protocol (more secure, more time-consuming). This segmentation allows the system to use the appropriate level of authentication complexity based on the results of the first phase, reducing overall system complexity while maintaining high security standards
3Reliability
If authentication processing continues regardless of initial validation results, then comprehensive security checking is ensured, but energy consumption increases due to unnecessary processing
Solution Approach 1:
The patent applies partial action by conditionally executing only the necessary authentication steps. When the first authentication fails, the system performs only the first authentication and stops, avoiding the energy consumption of executing the second authentication. This partial execution strategy maintains security by performing sufficient verification while reducing energy waste from unnecessary processing

AI summary
A power receiving apparatus 200 wirelessly receives power from a power transmitting apparatus 100, mutually performs device authentications with the power transmitting apparatus 100, and determines content related to power reception on the basis of a result of a performed device authentication. The apparatus 200 is capable of performing control such that in response to success in an earlier performed device authentication among the authentications, another device authentication among the authentications is performed, and performing control such that in response to failure in the earlier performed device authentication, said another device authentication is not performed.
