How to Implement Privacy Preserving Networking in OMNeT++

To Implement Privacy Preserving Networking in OMNeT++, we need to design and emulate the network protocols and configure that select the user privacy and data protection and it can completed by integrating the algorithms like encryption, anonymization, and secure multiparty computation. The given below are the brief procedures on how to implement the Privacy Preserving Networking in OMNeT++ using the INET framework:

Step-by-Step Implementation

Understand Privacy Preserving Techniques

Privacy preserving techniques include:

Encryption: Make sure data is encrypted during transmission.
Anonymization: Protecting user identities and data.
Secure Multiparty Computation: To let the parties to jointly calculate a function over their inputs while keeping those inputs private.

Install OMNeT++ and INET Framework

Make sure we have OMNeT++ and the INET Framework installed.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project. Name the project like PrivacyPreservingNetworkSimulation.

Define the Network Topology

Generate a new NED file to describe the network topology that contain clients, servers, and routers.

Example: Privacy Preserving Network Topology (PrivacyPreservingNetwork.ned)

package privacypreservingnetwork;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

network PrivacyPreservingNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

client1: StandardHost {

@display(“p=100,300”);

}

client2: StandardHost {

@display(“p=300,300”);

}

router: Router {

@display(“p=200,200”);

}

server: StandardHost {

@display(“p=400,100”);

}

connections:

client1.ethg++ <–> Eth10M <–> router.ethg++;

client2.ethg++ <–> Eth10M <–> router.ethg++;

router.ethg++ <–> Eth10M <–> server.ethg++;

}

Configure the Simulation

Generate an OMNeT++ initialization file to configure the parameters of the simulation.

Example: Configuration File (omnetpp.ini)

network = privacypreservingnetwork.PrivacyPreservingNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Client Configuration

*.client*.numApps = 1

*.client*.app[0].typename = “PrivacyPreservingApp”

*.client*.app[0].destAddresses = “server”

*.client*.app[0].destPort = 5000

*.client*.app[0].messageLength = 1024B

*.client*.app[0].sendInterval = 1s

# Server Configuration

*.server.numApps = 1

*.server.app[0].typename = “PrivacyPreservingApp”

*.server.app[0].localPort = 5000

# UDP Configuration

*.client*.hasUdp = true

*.server.hasUdp = true

# IP Address Configuration

*.client1.ipv4.config = xmldoc(“client1.xml”)

*.client2.ipv4.config = xmldoc(“client2.xml”)

*.router.ipv4.config = xmldoc(“router.xml”)

*.server.ipv4.config = xmldoc(“server.xml”)

Create IP Address Configuration Files

Generate XML files to state the IP address configuration for each node.

Example: IP Configuration File for client1 (client1.xml)

</interface>

</config>

Example: IP Configuration File for client2 (client2.xml)

</interface>

</config>

Example: IP Configuration File for router (router.xml)

</interface>

</config>

Example: IP Configuration File for server (server.xml)

</interface>

</config>

Implement Privacy Preserving Application Logic

To mimic the privacy preserving communication so we need to execute the logic for data encryption, anonymization, and secure communication.

Example: Privacy Preserving Application (Pseudo-Code)

#include <omnetpp.h>

using namespace omnetpp;

class PrivacyPreservingApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void sendData();

void encryptData(cMessage *msg);

void anonymizeData(cMessage *msg);

};

Define_Module(PrivacyPreservingApp);

void PrivacyPreservingApp::initialize() {

// Initialization code

scheduleAt(simTime() + 1, new cMessage(“sendData”));

}

void PrivacyPreservingApp::handleMessage(cMessage *msg) {

if (strcmp(msg->getName(), “sendData”) == 0) {

sendData();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void PrivacyPreservingApp::sendData() {

// Logic to create and send a data packet

cMessage *msg = new cMessage(“data”);

encryptData(msg);

anonymizeData(msg);

send(msg, “out”);

}

void PrivacyPreservingApp::encryptData(cMessage *msg) {

// Logic to encrypt data

}

void PrivacyPreservingApp::anonymizeData(cMessage *msg) {

// Logic to anonymize data

}

Run the Simulation

Build the Project: Right-click on project and choose Build Project.
Run the Simulation: Click on the green play button in the OMNeT++ IDE to start the simulation.
