Device Pairing Authentication via Set ID and Identifying Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current short distance wireless communication methods, such as Bluetooth, require repetitive pairing processes for multiple devices, leading to inefficiencies and potential data security risks due to incorrect device pairing.
Innovation Solution
A device identifying method that establishes a connection with a member device to acquire a set ID and identifying keys, generates identifying data, and transmits it to candidate devices to determine whether they belong to a device set, ensuring secure and efficient pairing by authenticating candidate devices before pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional Bluetooth pairing method is used to connect with multiple devices, then connection capability is achieved, but pairing time increases significantly and security risks arise
Solution Approach 1:
The system performs preliminary actions by pre-establishing a trusted relationship between the identifying device and the first member device before actual pairing occurs. The set ID and identifying keys are acquired in advance from the first member device, creating a preparation phase that enables rapid authentication of subsequent candidate devices without repeating the full pairing process each time.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism using set ID and identifying keys that mediate between the identifying device and candidate member devices. This intermediary system verifies device identity without requiring direct trust establishment between each pair of devices, thereby streamlining the pairing process while maintaining security.
2Reliability
If traditional Bluetooth pairing method is used, then device connection is established, but risk of pairing with wrong device increases
Solution Approach 1:
The system implements feedback through the authentication process where the identifying device generates identifying data based on the set ID and identifying keys, transmits it to the candidate device, and verifies the response. This feedback loop confirms the candidate device's identity before allowing pairing, providing assurance that the correct device is being connected to and preventing unauthorized access.

AI summary
A device identifying method for identifying whether a candidate member device belongs to a device set or not by an identifying device. The device set comprising at least one member device. The method comprises: (a) establishing a connection between the identifying device and a first member device among the member device, to acquire a set ID and at least one identifying key from the first member device; (b) discovering the candidate member device according to the set ID; (c) generating identifying data according to the identifying key and transmitting the identifying data to the candidate member device; and (d) determining whether the candidate member device belongs to the device set or not according to a comparing result for the identifying data.
