How to Implement Network Privacy Control in OMNeT++
To implement network privacy control in OMNeT++ needs a functionality which guards the confidentiality of the data when it navigates the network. It can contain encryption, anonymization, access controls, and privacy-preserving protocols. The intent is to make sure that sensitive details are secured from illegitimated access or exposure.
Demonstration guide on how to implement network privacy control in OMNeT++:
Steps to Implement Network Privacy Control in OMNeT++
- Define the Network Environment:
- Build a network with nodes like workstations, servers, and routers. Integrate privacy control features like encryption modules, anonymization services, or privacy filters.
simple WorkstationModule
{
parameters:
@display(“i=block/pc”);
gates:
inout ethg;
}
simple ServerModule
{
parameters:
@display(“i=block/server”);
gates:
inout ethg;
}
simple PrivacyControlModule
{
parameters:
@display(“i=block/lock”);
gates:
inout ethg;
}
network PrivacyNetwork
{
submodules:
workstation: WorkstationModule;
server: ServerModule;
privacyControl: PrivacyControlModule;
switch: EthernetSwitch;
connections:
workstation.ethg <–> switch.ethg[0];
server.ethg <–> switch.ethg[1];
switch.ethg[2] –> privacyControl.ethg;
}
- Implement Encryption for Data Privacy:
- We have to simulate encryption and decryption of the data by generating a module. This ensures that data transmitted through the network is sheltered from eavesdropping or unauthorized access.
class PrivacyControlModule : public cSimpleModule {
protected:
virtual void handleMessage(cMessage *msg) override {
cPacket *pkt = check_and_cast<cPacket*>(msg);
// Encrypt the packet before forwarding
encryptPacket(pkt);
send(pkt, “ethg$o”);
}
void encryptPacket(cPacket *pkt) {
// Example encryption logic (simplified)
std::string data = pkt->getName(); // Assume packet name is the data
std::reverse(data.begin(), data.end()); // Simple “encryption” by reversing the string
pkt->setName(data.c_str());
EV << “Packet encrypted: ” << pkt->getName() << endl;
}
void decryptPacket(cPacket *pkt) {
// Example decryption logic (reverse the “encryption”)
std::string data = pkt->getName();
std::reverse(data.begin(), data.end()); // Reverse again to “decrypt”
pkt->setName(data.c_str());
EV << “Packet decrypted: ” << pkt->getName() << endl;
}
};
- Implement Anonymization for User Privacy:
- Add a module that anonymizes sensitive information like IP addresses or user identifiers, to shelter user privacy.
class AnonymizationModule : public cSimpleModule {
protected:
virtual void handleMessage(cMessage *msg) override {
cPacket *pkt = check_and_cast<cPacket*>(msg);
// Anonymize the packet before forwarding
anonymizePacket(pkt);
send(pkt, “ethg$o”);
}
void anonymizePacket(cPacket *pkt) {
// Example anonymization logic
pkt->addPar(“anonymized”) = true;
pkt->setName(“anonymousData”);
EV << “Packet anonymized” << endl;
}
};
- Implement Access Control for Privacy:
- Before permitting the data to be forwarded, we have to verify the access permissions by developing a module. This ensures that only authorized entities can access sensitive data.
class AccessControlModule : public cSimpleModule {
private:
bool authorized = false;
protected:
virtual void initialize() override {
authorized = false;
}
virtual void handleMessage(cMessage *msg) override {
cPacket *pkt = check_and_cast<cPacket*>(msg);
// Check if the packet should be allowed through
if (checkAuthorization(pkt)) {
EV << “Access granted for packet: ” << pkt->getName() << endl;
send(pkt, “ethg$o”);
} else {
EV << “Access denied for packet: ” << pkt->getName() << endl;
delete pkt;
}
}
bool checkAuthorization(cPacket *pkt) {
// Implement authorization logic here (e.g., check user roles, packet origin, etc.)
return authorized;
}
};
- Simulate and Evaluate Privacy Controls:
- Run simulations with various situations to assess how well the privacy controls guard data. Examine cases might contains attempts to intercept, decrypt, or access unauthorized data.
virtual void finish() override {
// Optionally, collect and record metrics about privacy control effectiveness
}
Example Scenario: Data Encryption and Access Control
In natural situations, data sent from a workstation to a server would first pass through an encryption module, ensuring that it is encrypted before being transmitted. The server, upon receiving the data, would decrypt it and then evaluating if the requestor has the required permissions to access the requested resource.
