Sybil Attack with RSU Detection and Location Privacy in Urban VANETs: An Efficient EPORP Technique

Abstract

Nowadays, Vehicular ad hoc networks (VANETs) has received interest in the research because it is used to provide the information for drivers and passengers. In the urban VANET, security and safety is a main issue in recent days because of different kinds of attacks. From the attacks, Sybil attack can be considered as a very difficult for urban VANET networks. Hence, in this paper Emperor Penguin Optimization based Routing protocol (EPORP) is developed for detecting the Sybil attack as well as increasing the system performance. The main objective of the research is detecting the Sybil attack as well as improve the security in VANETS. The initial objective is achieved with the help of Rumour riding technique which detect the Sybil attack in the urban VANET.Similarly, the security of the system is achieved with the help of Split XOR (SXOR) operation. In the SXOR operation, the optimal key is generated with the assistance of Emperor Penguin Optimization (EPO). The proposed method is implemented in NS2 platform and performances are evaluated by metrics such as delay, throughput, delay, encryption time and decryption time. The proposed method is compared with existing methods such as Whale Optimization Algorithm (WOA), Particle Swarm Optimization (PSO) and Firefly Algorithm (FA) respectively. While analyzing the delivery ratio, the proposed method has 0.96sec and the WOA, PSO and FA is 0.94, 0.92 and 0.90 respectively. From the analysis, the proposed method has the high delivery ratio value compared with the WOA, PSO and FA methods. Similarly, the other parameters are analyzed and compared with the existing methods.

Developing an optimized routing protocol with rumor riding technique for detection of Sybil attack in VANET environment

“…The ensuing procedure, which is dependent on the value of WILLING and the addition of a novel element, will determine the final reputation of a node. 13…”

“…Optimization‐based routing protocol was designed by Velayudhan et al 13 to identify the Sybil attack, which improves the security of VANETs. In order to improve VANET security, the researcher focus on identifying the Sybil attack.…”

“…The same criteria are still applied when choosing as to which node will forward the RREQ packet. The ensuing procedure, which is dependent on the value of WILLING and the addition of a novel element, will determine the final reputation of a node 13 …”

Privacy and security issues surrounding vehicular Adhoc networks

“…The primary goal of a Sybil attack in VANETs is to compromise the integrity and reliability of the network by creating numerous malicious nodes (Sybil nodes) that collaborate to disrupt communication, spread false information, or manipulate network protocols. As shown in Figure 9, Sybil attacker generates multiple fake identities, each with a unique pseudonym, to gain influence or control over the network [165], [166]. Sybil nodes collaborate to amplify the impact of malicious activities, such as injecting false traffic information, disrupting routing protocols, or causing confusion in safety applications.…”

Investigation of Different Mechanisms to Detect Misbehaving Nodes in Vehicle Ad-Hoc Networks (VANETs)

“…Protocol)-Based Secure Protocol. Te EPORP-secured protocol, as suggested in reference [74], has been proposed to augment the system's security and detect the existence of Sybil attack nodes. In the context of vehicular ad-hoc networks (VANETs), detecting Sybil attacks is crucial to mitigate instances of system failure.…”
