  • Machine Learning-Driven Intrusion Detection for Next-Generation Information Security Systems
    Rabins Porwal, Manoj Singh Adhikari, Keerthi S, Anil Kumar Yadav, Mahesh Babu Ketha, et al.
    International Research Journal of Multidisciplinary Technovation, 2026
    The proliferation of cloud, IoT, edge, and 5G infrastructures has dramatically expanded the attack surface of modern networks, while many existing intrusion detection systems (IDS) remain centralized, poorly interpretable, and brittle to concept drift and adversarial manipulation. Traditional machine learning-based IDS architectures demand centralization of raw data, offer limited decision transparency, degrade as traffic distributions evolve, and scale poorly to privacy-sensitive and resource-constrained deployments. In this paper, the Adaptive Explainable Federated Intrusion Detection System (AEF-IDS) is proposed, incorporating privacy-preserving federated learning, Kolmogorov-Smirnov (KS) test-based drift detection, differential privacy, adversarial robustness training, and multi-level explainability within a unified edge-oriented framework. Evaluated on three widely adopted benchmarks, namely NSL-KDD, UNSW-NB15, and CIC-IDS2018, AEF-IDS achieves detection accuracies of 96.74%, 93.92%, and 95.87%, false positive rates of 1.68%, 2.61%, and 2.19%, and AUC-ROC scores of 0.9781, 0.9573, and 0.9683, respectively. The system satisfies strict real-time performance requirements, achieving per-sample inference latencies of 47.3, 44.8, and 46.1 ms across the three benchmarks, all within the 50 ms operational threshold. AEF-IDS further demonstrates high resilience against white-box adversarial attacks, including FGSM, PGD, C&W, and DeepFool, maintaining a mean under-attack detection accuracy exceeding 88% across all evaluated datasets. Through federated optimization and KS-triggered adaptive retraining, the system effectively mitigates distributional shift while preserving local data sovereignty, and SHAP/LIME-based explanations provide both global and local attribution transparency for security analysts. These results collectively demonstrate that AEF-IDS constitutes a robust, privacy-preserving, and interpretable solution for next-generation IDS deployment at the network edge. Future work will address cross-domain generalization, online hyperparameter adaptation, and large-scale real-world field validation.
  • A Federated Learning–Enabled Secure and Scalable SDN Framework for Energy-Efficient VANETs
    S. Sathishkumar, S. Keerthi, R. Devi Priya, Sivanantham S
    International Journal of Communication Systems, 2026
    Vehicular ad hoc networks (VANETs) play a central role in intelligent transportation systems (ITSs), yet their performance is often constrained by high mobility, limited scalability, privacy risks, and increasing security threats, including quantum‐enabled attacks. Existing approaches typically integrate software‐defined networking (SDN), federated learning (FL), blockchain, or cryptographic techniques in isolation, resulting in fragmented control and inconsistent security guarantees. To overcome these limitations, this work proposes FLEDGE‐SDVN , a unified FL‐enabled, blockchain‐secured, and postquantum‐resilient SDN framework for secure and energy‐efficient VANET operation. The framework employs dynamic hierarchical clustering for stable topology management and incorporates an FL‐based trust model to detect malicious vehicles without sharing raw data. A lightweight blockchain ensures tamper‐resistant maintenance of trust records, while Kyber‐ and Dilithium‐based postquantum cryptography provides long‐term secure authentication. SDN controllers enforce global routing policies, optimize traffic flow, and support adaptive decision‐making. Extensive NS‐3 and SUMO simulations demonstrate that FLEDGE‐SDVN significantly enhances network performance compared to CRAS‐FL, EECT, and DistB‐VNET. Specifically, the framework improves packet delivery ratio by 10%–22%, reduces end‐to‐end delay by 13%–28%, enhances energy efficiency by 17%–31%, and achieves trust accuracy up to 96%. These results confirm that FLEDGE‐SDVN offers a scalable, secure, and future‐ready solution for next‐generation vehicular communication systems.
  • Forensic Audit Trails and Biometric-Based Authentication
    Deepak Gupta, Raghu Nangunuri, Srinivasan Nagaraj, S. Keerthi, Pratish Rawat, et al.
    Exploring the Intersection of Forensics and Biometrics, 2026
    Forensic audit trails combined with biometric-based authentication represent a critical convergence in modern cybersecurity infrastructure. This chapter examines the technical implementation, forensic methodologies, and investigative frameworks for biometric authentication systems. The integration of immutable audit trails with biometric verification creates comprehensive forensic evidence chains essential for digital investigations. We analyze forensic challenges including spoofing attacks, presentation attacks, and biometric template security. The chapter explores multimodal biometric systems, liveness detection mechanisms, and blockchain-based audit trail implementations. Critical examination of privacy-preserving forensic techniques, GDPR compliance, and admissibility of biometric evidence in legal proceedings provides practical guidance. Real-world case studies demonstrate forensic analysis of compromised biometric systems.

    Detection and segmentation of brain tumors is important in the healthcare domain. Since brain tumors can possibly lead to cancer, it is a crucial task to detect it early through Magnetic Resonance Imaging (MRI) or Computed Tomography (CT), which are the techniques that use radio waves and magnetic fields to present a detailed view of the body organs. The images obtained from the MRI makes it hard to locate the exact position of the tumor and hence it is a challenging task to detect the tumor accurately. Thus, computer-aided methods (segmentation, detection and classification processes) with better accuracy are required for early tumor diagnosis. The segmentation of brain tumor which is usually carried out manually by the radiologists through their expertise and skill is a highly prolonged task and there can be chances of some faulty predictions, hence, the semantic segmentation is proven to be an effective method to overcome this problem. Semantic segmentation method is applied to brain tumors which are automatically segmented with the aid of deep learning techniques (CNN, RNN, GAN, LSTMs, etc.). The usage of deep learning techniques with greater accuracy and robustness are proven to be effective for the precise diagnosis of brain tumor. The primary objective of this paper is to examine the previously published techniques using deep learning for the human brain tumor prediction.
  • RFID based Smart Traffic System for Emergency Vehicles

    The traffic congestion problem is an issue that has had a significant influence on the country's transportation system. This creates a slew of issues particularly when there are emergencies at traffic signal junctions, which are constantly congested. These issues are addressed by a traffic light control system. This system was created to run when it received a signal from an emergency vehicle through radio frequency (RFID) transmission and utilized the Programmable Integrated Circuit Arduino microcontroller to return the sequence to normal before the emergency mode was activated. Because another vehicle had to follow a particular path to the emergency car, this technique will decrease accidents that occur often at traffic signal crossings. As a consequence, the project successfully studied and implemented wireless communication in the traffic light control system for emergency vehicles, as well as radio frequency (RFID) transmission. When emergency vehicles pass by a junction, the prototype of this project uses the 434 MHz frequency and operates with the sequence mode of a traffic light, shifting the sequence back to the usual sequence before the emergency mode is activated. This prototype system can be enhanced in the future by regulating real-world traffic conditions, effectively upgrading current traffic signal system technology.
