Virtual Device Information for Wireless Connection Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection methods for electronic devices, such as smartphones and wearables, require individual authentication and link key generation for each device, leading to delayed connections and user inconvenience, especially when multiple devices are connected to a hub that needs to be replaced in a network.
Innovation Solution
A method involving the use of virtual device information and connection information to establish connections through short-range wireless communication, allowing a first electronic device to acquire and utilize virtual device information associated with a second electronic device to connect with third devices, thereby eliminating the need for individual authentication and link key generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual authentication and link key generation is performed for each device connection, then connection security is ensured, but connection time increases and user convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-generating link keys between the hub device and each connected device before actual connection is needed. When a device connects to the hub, the pre-generated link keys are immediately used, eliminating the need for real-time key generation and authentication, thus reducing connection time while maintaining security
Solution Approach 2:
The patent uses copying by creating virtual device information that includes pre-generated link keys. Instead of performing authentication procedures with the actual device each time, the system copies and uses virtual connection credentials that have been prepared in advance, allowing rapid reconnection without repeating the full authentication process
2Reliability
If authentication and link key generation is performed for each hub replacement, then network security is maintained, but network reconfiguration time increases and user inconvenience increases
Solution Approach 1:
When the hub device is replaced, the new hub obtains virtual device information from the old hub that contains pre-generated link keys. This copying of virtual connection credentials allows the new hub to immediately establish secure connections with all previously connected devices without requiring them to undergo authentication procedures again, thus maintaining security while enabling rapid network reconfiguration
Solution Approach 2:
The system performs preliminary action by pre-generating and storing link keys in virtual device information before hub replacement occurs. This allows the new hub to inherit these pre-prepared credentials, eliminating the need for time-consuming re-authentication with each device during hub replacement, thereby improving network reconfiguration speed

AI summary
Disclosed are an electronic device for making a connection with an external electronic device and a method of operating the same. A method of operating a first electronic device includes acquiring virtual device information associated with a second electronic device and connection information between the second electronic device and one or more third electronic devices, which is generated based on the virtual device information, and making a connection with the one or more third electronic devices through short range wireless communication by using the virtual device information and the connection information.
