Security, Privacy, Content Protection, and Digital Rights Management
accurately, shareable, and accessible only to
authorized users.
Integrity The stored and exchanged data must
be validated and verified in an edge server.
Thus, exchanged critical safety data should be
protected from unauthorized modifications. or
malware injections. The received data must be
authenticated in terms of source, location, and
content. In this way, the data should be protected
from various attacks and also ensured the
integrity of the received data.

Integrity and Authenticity of In-Vehicle
Communication The valid or unauthorized
traffic data transmitted from the moving vehicles
are verified and detected by the RSUs.
Integrity and Authenticity of Other
Vehicles The data received from vehicles and
RSUs in a network are verified and guaranteed to
provide authenticity to other connecting vehicles.
Confidentiality of Communication and
Data The vehicle broadcasts the captured data
to nearby RSU or another vehicle to update the
current road conditions. Thus, the broadcasted
data must be reliable and confidential to the
authorized users.
Vehicle-to-Edge (V2E) Layer
This layer is primarily responsible for storing
and processing the data from the vehicle's sensors
and sending traffic warning alerts to the
right users or vehicles. In this layer, the stored
or processed data should be authenticated and
protected from malware injection attackers.
Thus, the security requirements of V2E are
summarized as follows.
Confidentiality Confidentiality requirement
provides a guarantee to the stored and processed
data. These data should be encrypted

Access Control Most of the data, collected
from moving vehicles are important for an intelligent
traffic management system. With the help of
an access control mechanism, only authorized
users can able to access the data, and resources,
and private information.
Learning-Based Trust Management The
modern IoV system must adopt the traditional
attack detection strategy by developing a novel
machine or deep learning-based trust management
algorithm for connected vehicles. Thus,
the vehicles can estimate their future trust values
based on the present and past trust values.
Vehicle-to-Cloud (V2C) Layer
The third layer can be connected with the
internet to provide on-demand services or additional
services to authorized users. A single or
multiple vehicular cloud servers are deployed in
different locations to store and process the large
volume of traffic data. This layer must consider
the following security requirements for enhancing
the accessibility of their services.
Attack Detection This security requirement
enables the cloud server to effectively identify,
store, and alerts various internal and external
attacks. Thus, various attacks should be detected
on the cloud resources fromunauthorized access.
Integrity This requirement ensures the integrity
of the vehicular cloud server and other
tampering events.
Access Control This requirement provides
limited and controlled access to authorized
cloud users and other virtual cloud servers.
