Electronic Device Pairing Verification via Reference Data Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems with high security requirements face complex pairing and pairing monitoring processes, leading to increased time and effort in design, installation, and function checks, making them less user-friendly and prone to illegal sub-device replacements that can compromise confidentiality.
Innovation Solution
An electronic device with a control unit that utilizes reference data stored in sub-device memory sections, allowing the control unit to create, transmit, and compare reference data to ensure legitimate pairing and detect illegal sub-devices, thereby simplifying the pairing process and preventing unauthorized operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pairing process is implemented to ensure high security, then security reliability is improved, but device complexity and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-storing reference data in the sub-device memory sections before the actual pairing operation. The control unit creates and stores reference data corresponding to each sub-device in advance, so that during operation, pairing verification can be performed quickly by simply comparing current data against the pre-stored reference data, eliminating complex real-time pairing processes
Solution Approach 2:
The patent segments the pairing verification process into independent comparison operations for each sub-device. The control unit separately compares reference data for each sub-device against stored data, allowing modular and simplified processing of pairing verification for multiple sub-devices rather than handling them as a single complex process
2Reliability
If a conventional pairing monitoring process is implemented to detect illegal sub-devices, then security reliability is improved, but processing time increases
Solution Approach 1:
The patent replaces complex mechanical pairing monitoring procedures with a simple data comparison mechanism. Instead of performing elaborate verification routines, the control unit simply compares current sub-device data against pre-stored reference data in memory, achieving rapid and accurate detection of illegal sub-device connections through straightforward data matching
Solution Approach 2:
The patent uses copying by creating reference data copies that are stored in the control unit memory and sub-device memory sections. These copied reference data sets enable rapid comparison and verification without needing to access or process the original complex pairing information, significantly reducing processing time while maintaining monitoring accuracy
3Ease of operation
If reference data is pre-stored in sub-devices to simplify pairing, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the reference data storage structure to serve multiple functions: it enables pairing verification, supports monitoring of multiple sub-devices, and provides a template for future expansions. The same memory structure and comparison mechanism work universally across different sub-device types and scenarios, reducing the need for separate complex structures for each function
Data Source
AI summary
An electronic device and its pairing process and pairing monitoring process is provided, which, though relatively simple, can correctly judge if the electronic device connected to a host device and multiple sub-devices is a certified pair so that the replacement by an illegal sub-device can be detected. An electronic device that implements the process according to the command from the host device has a control unit. The control unit controls the electronic device and multiple sub-devices. The sub-devices have reference data memory sections that store reference data specific to the sub-devices. The control unit has a comparing section that refers to the reference data of each of the multiple sub-devices.
