Distributed Trust-Based Communication Encryption Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based communication systems are vulnerable to eavesdropping and malicious modifications during message transmission, as messages can be intercepted and altered by unauthorized devices.
Innovation Solution
Implementing distributed trust-based communication by generating a first encrypted message for the receiving device, coupling it with addressing data, and then generating a second encrypted message for the data transmission service, ensuring secure transmission and decryption at the intended endpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If messages are transmitted over the network in unencrypted form, then transmission simplicity and speed are improved, but security against eavesdropping and malicious modification deteriorates
Solution Approach 1:
The message transmission process is segmented into multiple encryption layers: first encryption for the receiving device, second encryption for the data transmission service, and optional third encryption for intermediate devices. Each layer serves a specific security function while maintaining transmission efficiency.
Solution Approach 2:
Multiple encrypted messages are nested within each other, with each encrypted message containing another encrypted message. The innermost message is encrypted for the receiving device, surrounded by外层加密 for intermediate services, creating a nested structure that protects the core message while enabling secure transmission through multiple parties.
2Object-affected harmful factors
If multiple encryption layers are applied to messages, then security against unauthorized access is improved, but device complexity and processing overhead increase
Solution Approach 1:
A data transmission service acts as an intermediary between the sending and receiving devices, handling the complex multi-layer encryption and decryption processes. This intermediary manages the nested encrypted messages, stripping outer encryption layers and forwarding inner messages, thereby reducing the complexity burden on endpoint devices.
Solution Approach 2:
The sending device performs preliminary encryption actions by applying multiple encryption layers to the message before transmission. This preliminary action prepares the message for secure transmission through various intermediaries, with each encryption layer pre-configured for specific decryption keys that will be available at different points in the transmission chain.
3Object-affected harmful factors
If encrypted messages are transmitted through intermediate services, then security during transmission is improved, but transmission time and processing duration increase
Solution Approach 1:
The encryption and decryption process is designed to maintain continuous useful action throughout the transmission chain. Instead of stopping and restarting processing at each intermediate node, the system continuously strips encryption layers and forwards messages, minimizing idle time and maintaining steady-state processing flow.
Solution Approach 2:
The system creates copies of the encrypted message at different encryption layers, with each copy prepared for specific intermediaries. This copying approach allows parallel processing where multiple encryption/decryption operations can occur simultaneously at different nodes, reducing overall transmission time compared to sequential processing.
Data Source
AI summary
A computer generates a first encrypted message by encrypting an unencrypted message for decryption at a receiving device. The computer couples the first encrypted message with addressing data associated with the receiving device to generate a coupled message. The computer generates a second encrypted message by encrypting the coupled message for decryption at a data transmission service. The computer transmits the second encrypted message via the data transmission service to enable the receiving device to read the unencrypted message.
