Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limited-performance electronic devices, such as wearable devices, face challenges in performing authentication due to restricted input capabilities, smaller screens, lower computation power, and increased vulnerability to external threats like hacking, making them unsuitable for reliable authentication processes.
Innovation Solution
An authentication method and apparatus that enables safe and reliable authentication by interworking between a limited-performance electronic device and a high-performance device, such as a smartphone, through mutual authentication requests, information storage, and reliability checks via an authentication server, ensuring secure service access when the authentication state is maintained.

Engineering Contradiction Analysis
1Weight of moving object
If authentication is performed using a limited-performance electronic device (e.g., wearable device), then portability is improved, but authentication reliability deteriorates due to limited input capabilities, smaller screens, lower computation power, and increased vulnerability to external threats
Solution Approach 1:
An authentication server acts as an intermediary between the limited-performance electronic device and the authentication system. The server receives authentication requests from the wearable device, performs the actual authentication processing, and returns authentication results. This mediator approach allows the wearable device to maintain portability while delegating complex authentication operations to a more powerful server, thereby resolving the contradiction between portability and authentication reliability.
Solution Approach 2:
The authentication system is segmented into multiple components: the limited-performance electronic device handles user interaction and basic communication, while the authentication server handles complex authentication processing. This segmentation allows each component to perform its specialized function optimally - the wearable device maintains portability while the server ensures authentication reliability through superior computational resources and security measures.
2Speed
If authentication processing is performed locally on the electronic device, then authentication speed is improved, but device complexity increases due to requirements for I/O interfaces, communication interfaces, and processors
Solution Approach 1:
The authentication server serves as an intermediary that centralizes complex authentication processing external to the electronic device. This approach reduces device complexity by eliminating or minimizing the need for sophisticated I/O interfaces, communication interfaces, and processors within the device itself, while maintaining efficient authentication speed through optimized server-side processing and streamlined client-server communication.
3Weight of moving object
If the electronic device is miniaturized to improve portability, then portability is improved, but computation capability deteriorates
Solution Approach 1:
The authentication server acts as an intermediary computational resource that compensates for the limited computation capability of miniaturized devices. By delegating authentication processing to the server, the system maintains the portability benefits of miniaturization while achieving adequate computation capability through external resources.
Solution Approach 2:
Computational tasks are segmented between the miniaturized device and the authentication server. The device handles only lightweight tasks such as user interaction and message transmission, while the server handles computationally intensive authentication operations. This segmentation allows the device to remain miniaturized for portability while the system as a whole maintains sufficient computation capability.

AI summary
An authentication method and apparatus for an electronic device. A first electronic device transmits a mutual authentication request for the first electronic device and a second electronic device communication-connected with the first electronic device to an authentication server. The first electronic device receives mutual authentication information for each of the first electronic device and the second electronic device from the authentication server, and stores the mutual authentication information in the first electronic device and the second electronic device. The first electronic device determines whether reliability of an authentication state between the first electronic device and the second electronic device is maintained. The first electronic device acquires an authentication result for a service using the second electronic device from the authentication server by using the mutual authentication information for each of the first electronic device and the second electronic device, when the reliability is maintained.
