Wireless Charging Pad Secure Element Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging systems lack secure communication and verification capabilities, making it difficult for providers to authenticate and charge devices, especially in public settings where payment or loyalty programs are involved, and there is a need for secure data transmission between charging pads, receivers, and servers.
Innovation Solution
A wireless charging pad with a secure element for decrypting encrypted information and a method for secure communication between the pad, receiver, and server, using techniques like NFC, Bluetooth, or data modulation, to authenticate and verify payment information before charging, with the server validating transactions and updating loyalty databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging is implemented without secure communication, then charging functionality is simple and easy to operate, but security and authentication capabilities are insufficient
Solution Approach 1:
A secure element is introduced as an intermediary component within the charging pad to handle encrypted communication and authentication. This secure element acts as a mediator between the receiver and the external server, managing cryptographic operations and secure data exchange without requiring the entire charging system to be complex
2Reliability
If encrypted communication is added to wireless charging, then security and authentication are improved, but device complexity increases
Solution Approach 1:
The charging pad is segmented into distinct functional components: a standard controller for charging operations and a dedicated secure element for cryptographic operations. This segmentation allows the secure element to handle authentication and encrypted communication independently, preventing security complexity from overwhelming the entire system
3Reliability
If direct communication between pad and receiver is lost, then system simplicity is maintained, but charging reliability in public settings deteriorates
Solution Approach 1:
The system performs preliminary authentication and establishes secure communication channels before initiating charging. The secure element pre-establishes trusted relationships with authorized receivers and servers, so that even if direct pad-receiver communication is lost during charging, the pre-established security framework ensures transaction integrity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures secure and authenticated wireless charging transactions, enabling providers to manage payments and loyalty programs effectively, even in scenarios where direct communication between the pad and receiver is lost, by using encrypted communication and authentication procedures.

AI summary
A wireless charging apparatus and method utilizing a secure element is disclosed. Illustratively, a receiver containing a secure element securely communicates with a charging pad also equipped with a secure element. The communication can be used to establish the identity of the receiver and facilitate billing for the wireless charging. The charging pad may further communicate in a secure manner with a server to authenticate the identity and other information about the receiver before providing wireless charging. Direct communication between the receiver and server is also contemplated.
