Experimental Evaluation of Fully Homomorphic Encryption for Privacy-Preserving V2X Communication

Vehicle-to-Everything (V2X) communication requires continuous exchange of mobility data, but this information is highly sensitive and must be protected. Fully Homomorphic Encryption (FHE) enables computation directly on encrypted data and has recently been explored for Intelligent Transportation Systems (ITS), yet its...

A Lightweight Intrusion Detection System for Constrained IoT Devices

Traditional Internet of Things (IoT) security solutions often rely on heavy cloud-based or gateway-class infrastructure, which is frequently unsuitable for resource-limited hardware due to latency, power, and memory constraints. This paper proposed a resource-aware behavioral Intrusion Detection System (IDS) designed f...

Mitigating Sybil Attacks in V2X Communication Through Cryptographic Trust Anchors

Vehicle-to-Everything (V2X) communication enables vehicles to exchange safety-critical messages, but its reliance on temporary pseudonymous identities makes it vulnerable to Sybil attacks, where a single attacker fabricates multiple identities to inject false information into the network. This paper presents a lightwei...

Lightweight IoT Node Offloading Framework for Real-Time Edge Analytics

The rapid growth of Internet of Things (IoT) deployments has intensified the need for efficient, decentralized computation management at the network edge. This paper presents a lightweight, neighbor-aware one-hop task offloading framework designed for resource-constrained IoT networks. The proposed adaptive scheme comb...

A Hybrid Blockchain-Based Zero-Trust Architecture for Secure and Scalable IoT Systems

The growth of the Internet of Things (IoT) has introduced significant security challenges, mainly due to the resource constraints of devices and the limitations of centralized architectures. This paper proposes a blockchain-based Zero-Trust framework for secure and scalable IoT systems. The approach is architecture-agn...

Simulating Cyber Attacks and Countermeasures in Vehicular Ad-Hoc Networks Using Cyber Operations Research Gym (CybORG)

Vehicular Ad-Hoc Networks (VANETs) enable realtime communication for safety-critical applications including collision avoidance and traffic control. Their decentralized, dynamic architecture, however, makes them vulnerable to multiple attack classes, including Sybil, spoofing, Denial-of-Service (DoS), and other cyber t...
