NFC Remote Control Rotating Access Pin Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NFC enabled remote controls cannot store dynamically changing rotating access pins, rendering them ineffective for connecting to peripheral devices that require such security measures.
Innovation Solution
An NFC enabled remote control establishes a connection with a compute device and a peripheral device by storing access credentials in its NFC tag, requesting and retrieving the current rotating access pin number from the peripheral device, and packaging these credentials for transmission to the compute device to establish a connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating access pin is used for security, then security is improved, but the convenience of NFC enabled remote control is lost because the pin cannot be stored in the static NFC tag
Solution Approach 1:
The patent applies dynamics by making the access pin dynamic rather than static. The remote control device dynamically requests and retrieves the current rotating access pin from the peripheral device before each connection attempt, allowing the pin to change over time while maintaining NFC convenience. This resolves the contradiction by enabling both security (through rotating pins) and convenience (through NFC remote control).
Solution Approach 2:
The remote control device serves as an intermediary between the compute device and the peripheral device. It retrieves the current rotating access pin from the peripheral device and packages it with other credentials to transmit to the compute device. This intermediary approach allows the static NFC tag to work with dynamic pins by having the remote control fetch and forward the current pin value.
2Ease of operation
If the access pin is stored in the NFC tag, then ease of operation is improved, but security is worsened because the pin can be read by anyone with an NFC reader
Solution Approach 1:
The system performs preliminary action by having the remote control device retrieve the current rotating access pin from the peripheral device before packaging and transmitting it to the compute device. This ensures that the pin used for connection is the current, unexpired pin, preventing the use of stolen or outdated pins while maintaining ease of connection through NFC.
Solution Approach 2:
The patent changes the parameter of the access pin from a static stored value to a dynamic retrieved value. Instead of storing a fixed pin in the NFC tag, the system retrieves the current pin value from the peripheral device at the time of connection, effectively changing the pin parameter to be time-dependent and thus more secure while maintaining convenient NFC operation.
3Ease of manufacture
If a static NFC tag is used in the remote control, then manufacturing simplicity is improved, but adaptability to rotating access pins is lost
Solution Approach 1:
The remote control device achieves universality by performing multiple functions: it stores static credentials (SSID, password) in the NFC tag for easy manufacturing, while also dynamically retrieving rotating access pins from the peripheral device. This multi-functionality allows the same simple NFC tag structure to work with both static and dynamic authentication requirements, maintaining manufacturing simplicity while achieving adaptability.
