analysis and traffic management. The main goal
of V2C communication is to increase intelligent
decision making, monitor vehicles remotely,
optimize traffic and traveling costs, and improve
safety for participants.
The abovementioned communication strategies
can be achieved through a secured and reliable
IoV systemfor data transmissionand storage.
ATTACKS IN EDGE-CENTRIC IOV
The security attack in the edge-centric IoV
system is one of the most crucial issues due to
frequent topology changes, distribution of
vehicles, a large volume of traffic data, limited
transmission power, etc. This IoV system supports
various transmission modes including
vehicle-to-infrastructure (V2I), vehicle-to-sensor
(V2S), vehicle-to-network (V2N), vehicle-to-pedestrians
(V2P), vehicle-to-device (V2D), vehicle-toedge
(V2E), vehicle-to-cloud (V2C), and vehicle-tovehicle
(V2V) to improve the safety on the road and
provide intelligent traffic management and more
convenience to the drivers, as shown in Figure 2.
However, if there is any network intrusion, the
vehicles can be controlled by attackers, which
leads to severe accidents, deaths, and also affects
the people on the roadside. There are several types
of security attacks,5 which can affect the overall
services and operations of the intelligent transport
system, as depicted inTable 1.
Denial of Service Attack In the Denial-of-Service
(DoS) attack, the attacker intends to disrupt
the normal traffic and reduces the performance
of the network by flooding the target with irrelevant
messages. The primary target of the
attacker would be the RSU, which acts as a core
component to authenticate, manage, and update
the vehicle's information.
Blackhole Attack In IoV, a malicious node
sends false route information to other participating
vehicle nodes. This introduces itself as an
optimum route and causes other vehicles to
route the traffic information via malicious ones,
i.e., no traffic can move through the network to
