To implement the Big Data security in ns3, a node that signifies the big data components like data producers, data processors and data consumers together with potential attackers by simulating secure communication amongst them. The mechanisms contain encryption, authentication and breach detection. We are responsible for implementing Big Data security in the ns3 program drop us your project details for more guidance.
Below, we provide a step-by-step guide to implement big data security in ns3:
Step-by-Step Implementation
Step 1: Set Up the ns3 Environment
Make certain, ns3 is installed in your computer.
Step 2: Define the Network Topology
Create a network topology which contains nodes representing Big Data components and possibly an attacker.
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/point-to-point-module.h”
#include “ns3/applications-module.h”
using namespace ns3;
NS_LOG_COMPONENT_DEFINE (“BigDataSecurityExample”);
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer dataProducers;
dataProducers.Create (2); // Data producers
NodeContainer dataProcessors;
dataProcessors.Create (2); // Data processors
NodeContainer dataConsumers;
dataConsumers.Create (2); // Data consumers
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (0), dataProcessors.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (1), dataProcessors.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (0), dataConsumers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (1), dataConsumers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataConsumers.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (dataProducers);
stack.Install (dataProcessors);
stack.Install (dataConsumers);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure applications…
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 3: Simulate Communication
Simulate communication between Big Data components by creating an application.
Data Producer Application:
class DataProducerApplication : public Application {
public:
DataProducerApplication () : m_socket (0) {}
virtual ~DataProducerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&DataProducerApplication::HandleRead, this));
Simulator::Schedule (Seconds (2.0), &DataProducerApplication::SendData, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
} }
private:
void SendData () {
Ptr<Packet> packet = Create<Packet> ((uint8_t*)”data”, 4);
m_socket->SendTo (packet, 0, InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080)); // Send to data processor
Simulator::Schedule (Seconds (5.0), &DataProducerApplication::SendData, this);
}
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Data Producer received: ” << packet->GetSize ());
}
}
Ptr<Socket> m_socket;
};
Data Processor Application:
class DataProcessorApplication : public Application {
public:
DataProcessorApplication () : m_socket (0) {}
virtual ~DataProcessorApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&DataProcessorApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Data Processor received: ” << packet->GetSize ());
// Process data and respond if necessary
std::string responseData = “processed-data”;
Ptr<Packet> responsePacket = Create<Packet> ((uint8_t*)responseData.c_str (), responseData.size ());
m_socket->SendTo (responsePacket, 0, InetSocketAddress::ConvertFrom (from));
}
}
Ptr<Socket> m_socket;
};
Data Consumer Application:
class DataConsumerApplication : public Application {
public:
DataConsumerApplication () : m_socket (0) {}
virtual ~DataConsumerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&DataConsumerApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Data Consumer received: ” << packet->GetSize ());
}
}
Ptr<Socket> m_socket;
};
Step 4: Implement Security Mechanisms
Simulate security mechanisms like encryption, authentication, and intrusion detection.
Authentication:
class AuthApplication : public Application {
public:
AuthApplication () : m_socket (0) {}
virtual ~AuthApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 7070);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&AuthApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
if (Authenticate (data)) {
NS_LOG_INFO (“Authentication successful from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
ForwardPacket (packet);
} else {
NS_LOG_WARN (“Authentication failed from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
}
bool Authenticate (const std::string& data) {
// Simplified authentication logic
return data == “valid-credentials”;
}
void ForwardPacket (Ptr<Packet> packet) {
Ptr<Socket> socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress remote = InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080); // Forward to another node
socket->Connect (remote);
socket->Send (packet);
socket->Close ();
}
Ptr<Socket> m_socket;
};
Encryption:
class EncryptionApplication : public Application {
public:
EncryptionApplication () : m_socket (0) {}
virtual ~EncryptionApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 6060);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&EncryptionApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
std::string decryptedData = Decrypt (data);
NS_LOG_INFO (“Received encrypted data: ” << data << “, decrypted data: ” << decryptedData);
}
}
std::string Decrypt (const std::string& data) {
// Simplified decryption logic
return data; // Assume data is already decrypted for simplicity
}
Ptr<Socket> m_socket;
};
Intrusion Detection System (IDS):
class IDSApplication : public Application {
public:
IDSApplication () : m_socket (0) {}
virtual ~IDSApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 5050);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&IDSApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
if (DetectIntrusion (data)) {
NS_LOG_WARN (“Intrusion detected from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
} else {
NS_LOG_INFO (“Normal traffic from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
}
bool DetectIntrusion (const std::string& data) {
// Simplified intrusion detection logic
return data == “malicious-pattern”;
}
Ptr<Socket> m_socket;
};
Step 5: Deploy Applications
In this network, inside the suitable nodes we have initialize and deploy the applications:
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer dataProducers;
dataProducers.Create (2); // Data producers
NodeContainer dataProcessors;
dataProcessors.Create (2); // Data processors
NodeContainer dataConsumers;
dataConsumers.Create (2); // Data consumers
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (0), dataProcessors.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (1), dataProcessors.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (0), dataConsumers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (1), dataConsumers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataConsumers.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (dataProducers);
stack.Install (dataProcessors);
stack.Install (dataConsumers);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Data Producer application
for (uint32_t i = 0; i < dataProducers.GetN (); ++i) {
Ptr<DataProducerApplication> producerApp = CreateObject<DataProducerApplication> ();
dataProducers.Get (i)->AddApplication (producerApp);
producerApp->SetStartTime (Seconds (1.0));
producerApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Data Processor application
for (uint32_t i = 0; i < dataProcessors.GetN (); ++i) {
Ptr<DataProcessorApplication> processorApp = CreateObject<DataProcessorApplication> ();
dataProcessors.Get (i)->AddApplication (processorApp);
processorApp->SetStartTime (Seconds (1.0));
processorApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Data Consumer application
for (uint32_t i = 0; i < dataConsumers.GetN (); ++i) {

dataConsumers.Get (i)->AddApplication (consumerApp);
consumerApp->SetStartTime (Seconds (1.0));
consumerApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Auth application

idsApp->SetStartTime (Seconds (1.0));
idsApp->SetStopTime (Seconds (20.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 6: Simulate an Attack
Simulate an attack to examine the security mechanisms that comes from the attacker node:
class AttackerApplication : public Application {
public:
AttackerApplication () : m_socket (0) {}
virtual ~AttackerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
m_peer = InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080); // Target data processor
m_socket->Connect (m_peer);
Simulator::Schedule (Seconds (3.0), &AttackerApplication::SendMaliciousPacket, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void SendMaliciousPacket () {
std::string maliciousData = “malicious-pattern”; // Simplified malicious pattern
Ptr<Packet> packet = Create<Packet> ((uint8_t*)maliciousData.c_str (), maliciousData.size ());
m_socket->Send (packet);
}
Ptr<Socket> m_socket;
Address m_peer;
};
int main (int argc, char *argv[]) {

dataProcessors.Create (2); // Data processors
NodeContainer dataConsumers;
dataConsumers.Create (2); // Data consumers
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (0), dataProcessors.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProducers.Get (1), dataProcessors.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (0), dataConsumers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (dataProcessors.Get (1), dataConsumers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (dataConsumers.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (dataProducers);
stack.Install (dataProcessors);
stack.Install (dataConsumers);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Data Producer application
for (uint32_t i = 0; i < dataProducers.GetN (); ++i) {
Ptr<DataProducerApplication> producerApp = CreateObject<DataProducerApplication> ();
dataProducers.Get (i)->AddApplication (producerApp);
producerApp->SetStartTime (Seconds (1.0));
producerApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Data Processor application

Ptr<DataProcessorApplication> processorApp = CreateObject<DataProcessorApplication> ();
dataProcessors.Get (i)->AddApplication (processorApp);
processorApp->SetStartTime (Seconds (1.0));
processorApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Data Consumer application
for (uint32_t i = 0; i < dataConsumers.GetN (); ++i) {
Ptr<DataConsumerApplication> consumerApp = CreateObject<DataConsumerApplication> ();
dataConsumers.Get (i)->AddApplication (consumerApp);
consumerApp->SetStartTime (Seconds (1.0));
consumerApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Auth application
Ptr<AuthApplication> authApp = CreateObject<AuthApplication> ();
dataProcessors.Get (1)->AddApplication (authApp);
authApp->SetStartTime (Seconds (1.0));
authApp->SetStopTime (Seconds (20.0));
// Create and configure the Encryption application

idsApp->SetStopTime (Seconds (20.0));
// Create and configure the Attacker application
Ptr<AttackerApplication> attackerApp = CreateObject<AttackerApplication> ();
attacker.Get (0)->AddApplication (attackerApp);
attackerApp->SetStartTime (Seconds (3.0));
attackerApp->SetStopTime (Seconds (4.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
