How to Implement Bio metric Security in OMNeT++
To implement the biometric security in OMNeT++, use biometric data (like fingerprints, facial recognition data or iris scan) for authentication which is required in the simulation network and also in modeling both the capture and verification processes includes securing transmission and storage of biometric data. We offered the demonstration to implement the biometric security in OMNeT++:
Step-by-Step Implementation:
- Set Up the OMNeT++ Environment:
- Install OMNeT++: Make certain that you have installed the OMNeT++.
- Install INET Framework: Download and install the INET framework, which will be used to model the network components.
- Define the Network and Biometric Devices:
Generate an network of devices that has biometric capture devices (example fingerprint scanners) and an authentication server.
Example NED File (BiometricNetwork.ned):
network BiometricNetwork
{
submodules:
scanner1: BiometricScanner {
@display(“p=100,100”);
}
scanner2: BiometricScanner {
@display(“p=300,100”);
}
authServer: AuthenticationServer {
@display(“p=200,300”);
}
connections:
scanner1.out –> authServer.in;
scanner2.out –> authServer.in;
authServer.out –> scanner1.in;
authServer.out –> scanner2.in;
}
Here, BiometricScanner indicates a device that captures biometric data, and AuthenticationServer is accountable for assessing the biometric information.
- Create a Biometric Scanner Module:
To simulates the capture and transmission of data by executing this module.
Example C++ File (BiometricScanner.cc):
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/common/packet/Packet.h”
#include “inet/common/packet/chunk/ByteCountChunk.h”
using namespace omnetpp;
using namespace inet;
class BiometricScanner : public cSimpleModule
{
private:
std::string biometricData = “user_fingerprint_data”; // Simulated biometric data
protected:
virtual void initialize() override {
// Simulate sending biometric data after a certain delay
cMessage *msg = new cMessage(“biometric_data”);
scheduleAt(simTime() + 1, msg);
}
virtual void handleMessage(cMessage *msg) override {
if (strcmp(msg->getName(), “biometric_data”) == 0) {
EV << “Sending biometric data to the server…\n”;
Packet *packet = new Packet(“biometric_packet”);
packet->insertAtBack(makeShared<ByteCountChunk>(biometricData));
send(packet, “out”);
delete msg;
} else {
// Process response from the server
Packet *pkt = check_and_cast<Packet*>(msg);
auto chunk = pkt->peekData<ByteCountChunk>();
std::string response = chunk->str();
EV << “Received authentication response: ” << response << “\n”;
delete pkt;
}
}
};
Define_Module(BiometricScanner);
- Create an Authentication Server Module:
Implement a module that simulates the authentication of biometric data and sends a response.
Example C++ File (AuthenticationServer.cc):
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/common/packet/Packet.h”
#include “inet/common/packet/chunk/ByteCountChunk.h”
using namespace omnetpp;
using namespace inet;
class AuthenticationServer : public cSimpleModule
{
private:
std::string storedBiometricHash = “hashed_user_fingerprint_data”; // Simulated stored biometric hash
std::string hashBiometricData(const std::string& data) {
// Simulate a simple hash function for biometric data
return std::to_string(data.length() * 42); // Placeholder for real hash calculation
}
protected:
virtual void handleMessage(cMessage *msg) override {
Packet *pkt = check_and_cast<Packet*>(msg);
auto chunk = pkt->peekData<ByteCountChunk>();
std::string receivedData = chunk->str();
EV << “Received biometric data: ” << receivedData << “\n”;
// Simulate biometric verification
std::string receivedHash = hashBiometricData(receivedData);
std::string response = (receivedHash == storedBiometricHash) ? “Authentication Successful” : “Authentication Failed”;
// Send response back to the scanner
Packet *responsePkt = new Packet(“response_packet”);
responsePkt->insertAtBack(makeShared<ByteCountChunk>(response));
send(responsePkt, “out”);
delete pkt;
}
};
Define_Module(AuthenticationServer);
- Integrate the Modules into the Network:
Make certain that the biometric scanner and confirmation server modules are properly linked and able to communicate in the network.
Example NED File (BiometricScanner.ned and AuthenticationServer.ned):
simple BiometricScanner
{
gates:
input in;
output out;
}
simple AuthenticationServer
{
gates:
input in;
output out;
}
- Simulate the Process:
- Use OMNeT++ to compile and run the simulation.
- The biometric scanners will capture and send biometric data to the authentication server.
- The authentication server validates the data and sends a response back to the scanners.
- Monitor the logs to see how biometric data is managed and whether authentication is successful.
- Secure the Biometric Data:
- Encryption: Before transmission, add the encryption to the biometric data to optimize the simulation. It can be accomplished by expanding the BiometricScanner module to encrypt data and the AuthenticationServer module to decrypt it.
- Authentication: Implement additional layers of security like mutual authentication amongst the scanner and server.
Example: Adding Encryption (BiometricScanner with Encryption):
std::string encrypt(const std::string& data, const std::string& key) {
std::string encrypted = data;
for (size_t i = 0; i < data.size(); ++i) {
encrypted[i] = data[i] ^ key[i % key.size()];
}
return encrypted;
}
virtual void handleMessage(cMessage *msg) override {
if (strcmp(msg->getName(), “biometric_data”) == 0) {
EV << “Encrypting and sending biometric data to the server…\n”;
std::string encryptedData = encrypt(biometricData, “securekey”);
Packet *packet = new Packet(“biometric_packet”);
packet->insertAtBack(makeShared<ByteCountChunk>(encryptedData));
send(packet, “out”);
delete msg;
} else {
// Process response from the server
Packet *pkt = check_and_cast<Packet*>(msg);
auto chunk = pkt->peekData<ByteCountChunk>();
std::string response = chunk->str();
EV << “Received authentication response: ” << response << “\n”;
delete pkt;
}
}
- Analyze the Results:
- Certify that biometric data is properly captured, transmitted, and authenticated.
- Make certain that encrypted data is securely managed.
- Estimate the influence of encryption on performance (for instance: latency).
- Extend the Simulation:
- Advanced Biometric Methods: Implement and simulate more intricate biometric data (like multi-factor authentication combining fingerprints and facial recognition).
- Attack Scenarios: Simulate attacks include data interception or spoofing, and monitor how the system responds.
- Scalability Testing: Raise the number of biometric devices and see how the network manages larger-scale authentication processes.
