Secure Storage Segmentation for Communication Device Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices connected to the Internet are vulnerable to unauthorized access, leading to potential malicious use and increased social harm due to the inability to prevent unauthorized rewriting of programs and data transmission.
Innovation Solution
A communication device with a storage unit having a secure area where reading and writing from a non-secure area are prohibited, storing a communication program and destination information, and allowing data transmission only through a controlled privileged mode to prevent unauthorized access and ensure secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device is connected to the Internet to enable automatic data collection and communication, then data transmission capability is improved, but vulnerability to unauthorized access and malicious use increases
Solution Approach 1:
The storage unit is divided into a first area (secure area) and a second area (non-secure area). The communication program and destination information are stored in the first area which is protected from reading and writing by programs in the second area. This segmentation isolates critical communication functions from unauthorized modification while allowing the device to remain connected to the Internet for data transmission.
2Adaptability or versatility
If a communication program is stored in a writable storage area to allow updates, then adaptability is improved, but security against unauthorized rewriting deteriorates
Solution Approach 1:
The storage unit is divided into a first area (secure area) and a second area (non-secure area). The communication program is stored in the first area which is protected from reading and writing by programs in the second area, ensuring program integrity while allowing the second area to remain writable for other purposes.
Solution Approach 2:
The communication program and destination information are pre-stored in the first area during device manufacturing or initial setup. This preliminary action ensures that critical communication functions are established before any potential unauthorized access occurs, and the protected area prevents subsequent unauthorized modifications.
3Ease of operation
If destination information is stored in an accessible storage area to enable flexible data transmission, then ease of operation is improved, but security against unauthorized data transmission deteriorates
Solution Approach 1:
The storage unit is divided into a first area (secure area) and a second area (non-secure area). Destination information is stored in the first area which is protected from access by programs in the second area. This ensures that data can only be transmitted to authorized destinations while maintaining the ability to update other parts of the system.
Solution Approach 2:
The first area acts as an intermediary layer between the communication unit and the second area. It mediates access to destination information by allowing the communication program (also in the first area) to read destination information while preventing programs in the second area from accessing or modifying it, thus controlling data transmission flows.

AI summary
It is desired to provide a technology that suppresses the possibility of unauthorized use of an electronic device.Provided is a communication device that includes a communication unit configured to transmit/receive data, and a storage unit that includes a first area and a second area different from the first area, and in the communication device, the first area is an area in which reading and writing from a program in the second area is prohibited, and the first area stores both of a communication program configured to control the transmission/reception and destination information of the data.
