IoT Device Program Distribution for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security technologies for IoT devices are inadequate due to limited hardware resources, making them vulnerable to hacking and data leakage, with no effective solutions available to protect the devices themselves.
Innovation Solution
An electronic device and operation method that distribute and store program parts between devices, where a first part is stored locally and a second part is received from an external device to perform specific functions, enhancing security by reducing resource demands and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based security solutions (TEE, SE) are applied to IoT devices, then security protection is improved, but device complexity and hardware resource requirements increase
Solution Approach 1:
The patent replaces hardware-based security mechanisms (TEE, SE) with a software-based security approach. The security function is transferred from the hardware domain to the software domain by dividing the program into first and second parts, where the first part is stored in the IoT device's memory and the second part is received from an external device. This substitution eliminates the need for complex hardware security modules while achieving security protection through software-based program distribution and execution control.
2Speed
If complete programs are stored and executed locally in IoT devices, then execution speed is improved, but security vulnerability increases
Solution Approach 1:
The patent segments the complete program into two distinct parts: a first part stored locally in the IoT device's memory and a second part received from an external device. This segmentation allows the critical security-related portion of the program (second part) to be obtained externally, reducing the attack surface on the IoT device while maintaining execution capability. The processor executes the program by combining both parts, achieving both speed and security benefits.
3Device complexity
If security functions are implemented in software rather than hardware, then device complexity is reduced, but execution time and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-storing the first part of the program in the IoT device's memory before execution is needed. When the device needs to execute the program, it only needs to receive and load the second part from the external device, rather than loading the entire program. This preliminary storage of the first part reduces the time required for program loading and execution while maintaining the security benefits of software-based implementation.
Data Source
AI summary
An electronic device that prevents damage and an operation method thereof are provided. The electronic device includes a transceiver, a memory configured to store a first part of a first program, and a processor configured to receive, using the transceiver, a second part of the first program from a second electronic device and perform a first function of the first program by using the first part and the second part.
