Federated Quantum Generative Adversarial Network for Intrusion Detection

In increasingly complex digital environments, Intrusion Detection Systems (IDS) are essential for maintaining network security. Traditional machine learning techniques face challenges, including difficulties with high-dimensional data and performance issues when dealing with unbalanced datasets. Although Generative Adversarial Networks (GANs) provide an acceptable alternative by improving data creation, their traditional implementations are computationally demanding and have limitations when it comes to examining intricate data distributions. Quantum GANs (QGANs) use the benefits of quantum computing to solve these problems. Therefore, a distributed approach improves load balancing and mitigate the impact of quantum noise for NISQ devices. The proposed model efficiently learns the distribution of benign data by employing a federated hybrid QGAN architecture that combines a quantum generators with a classical discriminators. This allows the model to produce samples that closely mimic patterns found in real data. The generator in the proposed QGAN is a variational quantum circuit (VQC), and the discriminator is a neural network. Tested on the NSL-KDD dataset, the federated QGAN offers a promising option for next-generation IDS.
