Message Segmentation for Secure Network Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security measures are inadequate in preventing data interception and decoding by packet sniffers and impersonation attacks, as they fail to effectively secure message transport over networks.
Innovation Solution
A method and apparatus that divide data into blocks of arbitrary size, assign unique identifiers, and generate reconstruction keys, which are then transmitted using various transport mechanisms, incorporating compression and encryption to enhance security and confuse interceptors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted as a single message over a network, then transmission is simple and fast, but security is vulnerable to packet sniffing and decoding
Solution Approach 1:
The patent applies segmentation by dividing the original message into multiple smaller blocks before transmission. Each block is independently encrypted and transmitted, making it difficult for packet sniffers to reconstruct the complete message. The receiver reassembles the blocks in the correct order using sequence numbers to restore the original message. This directly resolves the contradiction by improving security through segmentation while managing complexity through systematic block management.
2Reliability
If data is divided into multiple blocks for security, then security against packet sniffing improves, but transmission time and complexity increase
Solution Approach 1:
The message is segmented into blocks that can be transmitted in parallel or at different times, with sequence numbers enabling efficient reassembly. This segmentation allows for selective transmission and reduces the impact of any single block interception.
Solution Approach 2:
The sender pre-processes the message by dividing it into blocks, assigning sequence numbers, and preparing encryption keys before transmission begins. This preliminary segmentation and preparation enables faster transmission compared to real-time processing, as the blocking and numbering operations are performed in advance.
3Reliability
If encryption keys are transmitted separately from data blocks, then security is enhanced, but transmission complexity and potential vulnerability increase
Solution Approach 1:
The patent uses an intermediary approach by establishing a secure communication channel or using a key exchange protocol that allows the receiver to obtain the encryption key without direct transmission over the vulnerable network. The key is made available through a secure side-channel or pre-established mechanism, separating the key transmission from the data block transmission to enhance security while managing complexity.
Data Source
AI summary
Data is divided into a plurality of blocks. A unique identifier is assigned to each of the plurality of blocks. A key is generated that identifies how to reconstruct the data from the plurality of blocks. The key and each of the plurality of blocks are transmitted to a recipient.
