Distributed Trust-Based Message Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based communication systems are vulnerable to eavesdropping and modification by malicious actors, as messages transmitted over networks can be intercepted and altered during transmission, compromising privacy and security.
Innovation Solution
Implementing distributed trust-based message transmission by generating encrypted messages that can only be decrypted by the intended receiving device and data transmission service, ensuring secure communication through multi-layered encryption and decryption processes across various networks and messaging services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If messages are transmitted over a network, then communication between devices is enabled, but messages may be read by eavesdroppers or improperly modified by malicious actors
Solution Approach 1:
The message is segmented into multiple shares using secret sharing technology. Each share is distributed to different devices, and the original message cannot be reconstructed unless a threshold number of shares are combined. This segmentation prevents eavesdroppers from obtaining the complete message through interception of individual transmissions.
Solution Approach 2:
The patent implements nested encryption where the message is first encrypted with a secret key, then the ciphertext is further encrypted with public keys of multiple recipient devices. This multi-layered nesting ensures that even if outer layers are compromised, the core message remains protected until the correct number of shares are combined.
2Object-affected harmful factors
If encrypted messages are used to prevent eavesdropping, then security is improved, but the complexity of the communication system increases
Solution Approach 1:
Each participant device autonomously generates its own public-private key pairs and secret shares without requiring coordination with other devices. The system leverages the inherent capabilities of each device to perform cryptographic operations independently, reducing the need for complex centralized key management infrastructure.
Solution Approach 2:
The patent employs universal cryptographic primitives such as public-key infrastructure and secret sharing schemes that can be implemented across different device types and platforms. These standardized algorithms provide a unified approach to security that works consistently across diverse communication environments without requiring device-specific customizations.
3Object-affected harmful factors
If multiple encryption layers are applied to messages, then security against malicious actors is enhanced, but the processing time and computational resources increase
Solution Approach 1:
Public keys and secret shares are generated and distributed to devices before the actual message transmission occurs. This preliminary setup phase allows the expensive cryptographic materials to be prepared in advance, so that during actual message transmission, only the relatively lightweight encryption and decryption operations using pre-computed keys are required, reducing real-time processing delays.
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.
