Communication System Dummy Packet Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using multiple paths in a network face challenges in securing data transmission effectively, particularly in public networks, where security measures are complex and resource-intensive.
Innovation Solution
A communication system that employs a transmitter and receiver with multiple communication units and processors to selectively transmit packets through different paths, inserting dummy packets to enhance security by making it difficult for external devices to determine valid data, thereby simplifying the security configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dummy packets are inserted into packet groups transmitted through multiple communication paths, then security is improved by making it difficult for external devices to determine valid data, but device complexity increases due to the need for multiple communication units and processors
Solution Approach 1:
The communication system is divided into multiple independent communication paths (first and second communication paths) with separate communication units. Each path can independently transmit packet groups with dummy packets, allowing the system to achieve security through distributed transmission rather than centralized complex processing.
Solution Approach 2:
The system changes the transmission parameters by inserting dummy packets into packet groups at different communication paths. The first communication unit inserts dummy packets into first packet groups, while the second communication unit inserts dummy packets into second packet groups, altering the packet composition to enhance security without requiring complex processing logic.
2Reliability
If multiple communication paths are used for packet transmission, then security is improved, but communication load increases due to transmitting both valid and dummy packets
Solution Approach 1:
The system applies partial action by selectively inserting dummy packets into only some packet groups transmitted through each communication path, rather than all packets. This partial insertion provides sufficient security obscuration while avoiding the excessive communication load that would result from dummy packets in every transmission.
3Reliability
If dummy packets are inserted into packet groups, then security is improved by obscuring valid data, but manufacturing precision requirements increase for synchronizing communication patterns
Solution Approach 1:
The receiver creates a copy of the transmission-side communication pattern information and stores it in its own storage unit. This copied pattern information allows the receiver to synchronize and identify valid packets without requiring high-precision manual configuration or complex real-time synchronization mechanisms.

AI summary
In order to ensure security even when packet communication is performed using a plurality of communication paths of a public network, a transmitter stores a first communication pattern. First and second communication units perform packet communication with third and fourth communication units. The packet communication is performed in accordance with the first communication pattern, with dummy packets being inserted into at least one of the groups of packets to be transmitted. A processor restores original data from valid packets, which are remaining packets after the dummy packets are removed, in accordance with a second communication pattern.
