Secure Data Transmission via Operating System Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods in mobile phone terminals lack security, as the transmitter cannot determine if the reception environment is secure, leading to risks of data theft and eavesdropping.
Innovation Solution
Implementing a data transmission method that allows selection between normal and secure transmission modes, switching to a designated secure operating system for secure data transmission, and verifying the target terminal's support for secure transmission before establishing a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct connection is established between transmitter and receiver for data sharing, then data transmission efficiency is improved, but data security deteriorates due to inability to determine reception environment security
Solution Approach 1:
The patent performs preliminary security verification by checking whether the receiver is running a secure operating system before establishing the data transmission connection. This preliminary action prevents insecure receptions from receiving sensitive data, thereby resolving the contradiction between transmission efficiency and security.
2Reliability
If secure transmission mode is implemented with operating system switching, then data security is improved, but system complexity increases due to multiple operating systems and transmission modes
Solution Approach 1:
The patent segments the transmission process into distinct modes (normal transmission mode and secure transmission mode) with clearly defined switching conditions. This segmentation manages complexity by providing structured, rule-based transitions between states rather than requiring complex continuous control logic.
Solution Approach 2:
The patent implements dynamic switching between normal and secure transmission modes based on real-time conditions (whether secure reception is available). This dynamic approach allows the system to adapt its complexity level to the security requirements of the current transmission task.
3Reliability
If transmission mode switching between normal and secure modes is implemented, then data security is improved, but operation complexity increases for users
Solution Approach 1:
The patent implements automatic determination and switching between transmission modes based on the security status of the receiver. The system autonomously selects appropriate transmission modes without requiring manual user intervention, thereby maintaining ease of operation while ensuring data security.
Data Source
AI summary
A data transmission method and a terminal include multiple operating systems, and each operating system corresponds to a transmission module. The terminal determines a target transmission mode for data of the terminal when a data transmission command for transmitting the data of the terminal to a target terminal is received, and the target transmission mode includes a normal transmission mode and a secure transmission mode. The terminal switches to a designated operating system of the multiple operating systems when the target transmission mode is the secure transmission mode, establishes a connection with the target terminal via the designated operating system, determines whether the target terminal supports secure transmission, and transmits the data to the target terminal via the secure transmission mode when the determination result is that the target terminal supports the secure transmission.
