VANSec: Attack-Resistant VANET Security Algorithm in Terms of Trust Computation Error and Normalized Routing Overhead

Abstract

VANET is an application and subclass of MANETs, a quickly maturing, promising, and emerging technology these days. VANETs establish communication among vehicles (V2V) and roadside infrastructure (V2I). As vehicles move with high speed, hence environment and topology change with time. There is no optimum routing protocol which ensures full-pledge on-time delivery of data to destination nodes, and an absolutely optimum scheme design for flawless packet exchange is still a challenging task. In VANETs, accurate and on-time delivery of fundamental safety alert messages (FSAMs) is highly important to withstand against maliciously inserted security threats affectively. In this paper, we have presented a new security-aware routing technique called VANSec. The presented scheme is more immune and resistive against different kinds of attacks and thwarts malicious node penetration attempts to the entire network. It is basically based on trust management approach. The aim of the scheme is to identify malicious data and false nodes. The simulation results of VANSec are compared with already existing techniques called trust and LT in terms of trust computation error (TCE), end-to-end delay (EED), average link duration (ALD), and normalized routing overhead (NRO). In terms of TCE, VANSec is 11.6% and 7.3% efficient than LT and trust, respectively, while from EED comparison we found VANSec to be 57.6% more efficient than trust and 5.2% more efficient than LT. Similarly, in terms of ALD, VANSec provides 29.7% and 7.8% more stable link duration than trust and LT do, respectively, and in terms of NRO, VANSec protocol has 27.5% and 14% lesser load than that of trust and LT, respectively.

Trusted Opportunistic Routing Based on Node Trust Model

“…Due to the sensitivity of the information involved in VANET, a safe and reliable environment is essential [12]. However, because of its poor defense capabilities against various attacks (such as man-in-the-middle attacks, Sybil attacks, black hole attacks, or denial of service attacks), ensuring the security of VANET is very challenging [13,14]. In recent years, the trust model has been introduced as an effective security technology into the trusted environment for message propagation between vehicles.…”

VTD Protocol: A Cluster based Trust Model for Secure Communication in VANET

“…R. Hussain et al [18] proposed a secure and privacy-aware service for the VANET based cloud service. Ahmed, S., et al [19] have presented a VANSec technique for the securityaware routing in VANET. P. Yang et al [20] have proposed a socially aware security message forwarding mechanism for the VANET communication.…”

“…But in the literature, in the existing systems [16,19,22] intrusion and malicious attacks were found using the trust model. In some techniques [17,21] the natural inspired soft computing techniques are adopted to achieve the trust ability in the VANET routing.…”

Novel framework using dynamic passphrase towards secure and energy-efficient communication in MANET

“…Trust-based approach towards three distinct layers (physical, network, and MAC) has been carried out by Ghugar et al [16] focusing on resisting jamming / cross-layer attack in adhoc network. Ahmed et al [17] have also used trust-based scheme considering vehicular network.…”
