“…The transmitted message is confirmed and checked by the receiving node/vehicle; whether the received data is correct or having some false information is called data check. Nonrepudiation is the process in which the sender of a message cannot disown himself from the communication at 3 Journal of Sensors the end of the communication session [8]. Data correlation can also be considered a security requirement which easily finds out bogus data, by correlation to finger out the similarity between the data received and the data transmitted.…”

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.

“…However, as we seek to create innovative applications for VANETs, the concern of the implementation of security within these applications is worth heeding [15]. One of the main security problems that exists in VANETs is maintaining a vehicle's location privacy [2] [3][11] [16].…”

Modeling Adversarial Insider Vehicles in Mix Zones Nicholas PlewtongSecurity is a necessity when dealing with new forms of technology that may not have been analyzed from a security perspective. One of the latest growing technological advances are Vehicular Ad-Hoc Networks (VANETs). VANETs allow vehicles to communicate information to each other wirelessly which allows for an increase in safety and efficiency for vehicles. However, with this new type of computerized system

Summary Cooperative Intelligent Transportation System (C‐ITS) is a growing research field since it improves traffic safety and efficiency. However, the security of C‐ITS messages is an important issue to deal with. This paper proposes a cost‐efficient solution that can help in the deployment of C‐ITS. The idea herein presented is to introduce trusted road operator vehicles (ROVs), to provide certificates for other vehicles when needed. These certificates, which are generally provided by roadside units (RSUs), are mandatory for the security and the anonymity of the communication. The main objective of this work is to help in enhancing the security of C‐ITS by allowing connected vehicles to download the needed certificates without using a physical fixed infrastructure of RSUs. The latter cannot be, in fact, widely deployed due to their high cost. The alternative herein proposed is to delegate the task of providing certificates to some trusted vehicles, namely, ROVs, which are in all the cases moving around the city to ensure some assigned missions. A mathematical model, considering both ROVs and RSUs, is proposed to quantify the effects of introducing ROVs on the probability of downloading certificates. The results show that ROVs almost double the communication probability between the vehicles and the certificate providers from 40.1% to 78.7% on a highway with a high traffic density. The higher the communication probability, the easier downloading certificates is. Moreover, realistic simulations are conducted using Simulation of Urban Mobility (SUMO) traffic simulator together with Network Simulator 3 (NS3) network simulator to show the efficiency of our proposal. The simulation results demonstrate a significant enhancement in the number of downloaded certificates and the number of exchanged messages, even when a few numbers of ROVs are introduced.
