Abstract
Cache poisoning attacks in Vehicular Named Data Networking (V-NDN) pose a serious threat by injecting false content into the Content Store, compromising network integrity. This paper proposes a threshold-based reputation algorithm to detect and mitigate such attacks in V-NDN using ndnSIM with a V2V multi-hop topology of 31 nodes across three urban road segments. The algorithm assigns reputation values to all nodes, applying penalties for malicious behavior and blocking nodes below a threshold of 0.5. Two scenarios are evaluated: an attack scenario without mitigation and an attack scenario with the proposed reputation algorithm. Results show a Detection Rate (DR) of 75%, False Positive Rate (FPR) of 0%, and False Cache Poisoning Rate (FCP) of 5.87%, with Cache Hit Ratio (CHR) improving from 28.94% to 30.99% after mitigation, confirming the algorithm's effectiveness in detecting and mitigating cache poisoning attacks in dynamic vehicular network environments.
Low Earth Orbit (LEO) satellite constellations are increasingly deployed to support global network coverage as Space Information Networks (SINs). However, they can suffer from forwarding misbehaviour, where satellites may drop packets either selfishly to save resources or maliciously to disrupt communication. As selfis...

Abstract This study addresses critical security vulnerabilities, energy constraints, and dynamic topology issues in mobile ad-hoc networks (MANETs). The primary goal is to develop a trust-aware secure routing protocol that isolates malicious node attacks while optimizing energy efficiency and quality of service (QoS) p...

This paper introduces a distributed lightweight method that exploits Sybil identities’ mobility correlation to detect the attack and disseminates detection results using a lightweight hashing function.
A Vehicular Ad-hoc Network (VANET) enables communication between vehicles (V2V) and roadside infrastructure (V2I). This technology aims to enhance road safety, traffic efficiency, and passenger comfort by sharing real-time information, such as hazard warnings, forming the backbone of Intelligent Transportation Systems...
