How to implement traffic analysis attack in OMNeT++

To implement a traffic analysis attack in OMNeT++ has needs to encompass the network simulation wherever the attacker tries to get the data about the communication patterns or content by evaluating the traffic among the nodes. This contains the timing analysis, volume analysis, or pattern recognition. The given below is the detailed procedures on how to implement the traffic analysis attack in OMNeT++ tool:

Step-by-Step Implementation:

Step 1: Set Up the OMNeT++ Environment

1. Install OMNeT++ and INET: Make sure that OMNeT++ and the INET framework are installed and configured.
2. Create a New Project: Open the OMNeT++ IDE and generate a new project for executing the traffic analysis attack.

Step 2: Define the Network Topology

1. Create Network Nodes: state the nodes in network such as clients, servers, and attackers in the .ned file.
2. Define Connections: Create connections among the nodes to mimic the network topology.

network TrafficAnalysisNetwork

{

submodules:

client1: StandardHost;

client2: StandardHost;

server: StandardHost;

attacker: AttackerNode;

connections:

client1.pppg++ <–> { delay = 10ms; datarate = 100Mbps; } <–> server.pppg++;

client2.pppg++ <–> { delay = 10ms; datarate = 100Mbps; } <–> server.pppg++;

attacker.pppg++ <–> { delay = 1ms; datarate = 100Mbps; } <–> client1.pppg++;

attacker.pppg++ <–> { delay = 1ms; datarate = 100Mbps; } <–> client2.pppg++;

}

Step 3: Implement the Attacker Node

1. Create Attacker Module: Describe the attacker node in a .ned file.

simple AttackerNode

{

gates:

input fromNetwork;

output toNetwork;

}

1. Write the C++ Code for the Attacker Node: To execute the attacker’s logic in a corresponding C++ class.

class AttackerNode : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

 

private:

void analyzeTraffic(cPacket *packet);

};

1. Implement Traffic Analysis Logic:
   • Intercept Packets: The attacker node intercepts packets that pass through it.
   • Analyze Traffic Patterns: Implement approaches to evaluate timing, size, and flow patterns to infer information about the communication.

void AttackerNode::initialize()

{

// Initialization code here

}

void AttackerNode::handleMessage(cMessage *msg)

{

if (auto packet = dynamic_cast<cPacket*>(msg)) {

analyzeTraffic(packet);

// Optionally, forward the packet to maintain the network operation

send(packet, “toNetwork”);

} else {

delete msg;

}

}

void AttackerNode::analyzeTraffic(cPacket *packet)

{

EV << “Attacker analyzing packet from ” << packet->getSenderModule()->getFullPath() << endl;

// Example: Log packet size and timestamp

simtime_t timestamp = simTime();

int packetSize = packet->getByteLength();

EV << “Packet size: ” << packetSize << ” bytes, Timestamp: ” << timestamp << endl;

// Perform additional analysis such as:

// – Timing analysis

// – Traffic volume analysis

// – Protocol or pattern recognition

}

Step 4: Integrate with the Network

1. Integrate Attacker with Network: Make sure that the attacker node is connected to the network and can observe traffic passing through it.
2. Simulate Legitimate Traffic: Make sure traffic-generating applications on the client nodes to mimic normal communication with the server.

void generateTraffic()

{

// Example: Generate a periodic request from the client to the server

cMessage *msg = new cMessage(“request”);

scheduleAt(simTime() + par(“requestInterval”).doubleValue(), msg);

}

Step 5: Test and Validate

1. Run Simulations: Run the simulation to see how the attacker node intercepts and analyses traffic.
2. Observe Attack Impact: Use OMNeT++’s logging and tracing features to monitor the impact of the attack on network communication.

Step 6: Analyse Results

1. Analyse Traffic Patterns: Review the logs and output from the attacker node to measure the patterns of communication it has intercepted.
2. Measure Effectiveness: measure the efficiency of the traffic analysis attack based on the data collected.
