Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of various electronic apparatuses in IoT technologies poses security vulnerabilities due to the potential for hacking, necessitating a method to enhance communication security.
Innovation Solution
An electronic apparatus and method that utilizes a secure operating system (OS) to establish secure communication connections by searching for and selecting terminals with secure and normal OS installations, generating and managing key values for secure communication, and maintaining connections through secure OS networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT services use various electronic apparatuses with normal OS, then service versatility is improved, but security vulnerability increases
Solution Approach 1:
The system divides electronic apparatuses into two segments: secure apparatuses with secure OS and normal apparatuses with standard OS. Secure apparatuses form a protected communication network that can selectively interact with normal apparatuses, allowing versatile IoT services while maintaining security boundaries through the dual-network architecture
Solution Approach 2:
Secure apparatuses act as intermediary nodes between normal apparatuses and the secure network. They receive control commands from the secure network and execute them on normal apparatuses, serving as a security mediator that enables normal apparatuses to participate in IoT services without directly exposing them to security risks
2Reliability
If secure OS is installed on all terminals, then communication security is improved, but device compatibility deteriorates
Solution Approach 1:
The secure OS apparatus is designed with multi-functionality to serve dual roles: it operates within the secure network using secure protocols and can also interface with normal OS apparatuses using standard protocols. This universal capability allows a single secure apparatus to communicate with both secure and normal devices, maintaining high device compatibility while ensuring security

AI summary
Provided are an electronic apparatus in which a normal operating system (OS) and a secure OS are installed and a method for controlling the electronic apparatus. The method for controlling the electronic apparatus includes searching for at least one external terminal in which a secure OS is installed, selecting a first terminal from among the at least one external terminal in which a secure OS is installed, in response to a first terminal being selected from the retrieved at least one external terminal, performing communication connection with the first terminal, searching for at least one terminal in which only a normal OS is installed, from among at least one external terminal that is capable of being communication-connected to the first terminal, and performing communication with a second terminal of the at least one terminal in which only the normal OS is installed, through the first terminal.
