Terminal Device Message Encryption via Channel Key Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current messaging applications lack end-to-end encryption, making messages vulnerable to eavesdropping during transmission, especially for sensitive information like business communications, which are not adequately protected by existing secure transfer modes.
Innovation Solution
A method that involves linking a communication interface to a communication channel, encrypting messages with a key specific to that channel, and transmitting the encrypted messages, using a terminal device to secure message transmission, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If messaging applications use standard transmission modes, then ease of operation is improved, but message security deteriorates
Solution Approach 1:
The patent introduces an encryption module as an intermediary component between the communication interface and the messaging application. This module automatically encrypts messages using a key before transmission and decrypts received messages, providing security without requiring user intervention. The encryption module acts as a mediator that transparently secures communications while maintaining ease of operation.
2Reliability
If encryption is implemented at the application level, then message security is improved, but device complexity increases
Solution Approach 1:
The patent merges the encryption and decryption functions into the existing communication interface or messaging application structure. By integrating the encryption module with the existing communication infrastructure rather than adding a separate standalone system, the patent provides enhanced security while minimizing the increase in device complexity. The encryption key is generated and managed within the existing device architecture.
