in this research paper, we are presenting the secure business communication (SBC) model and explain the components of proposed model. TPM is a security hardware module and it is used inside the smart vehicle. TPM is a core component of proposed SBC model and it will ensure secure communication between user and business parties in VANET.

2.  Vehicular ad-hoc network is a special kind of network in which
nodes (Vehicles) can communicate with each other on the road
and with its Infrastructure.

5.  The first aspect of the VANET Security R&D Ecosystem is the Academic Research.
Past researchers have contributed a lot of novel ideas in new life saving network.
 Vehicular Ad hoc Network (VANET) have been introduced to provide the
infrastructure for life saving applications.

6.  The second aspect of the VANET Security R&D Ecosystem is the car manufacturers which form
a big and important industry. Researchers proposed and designed the concept of smart vehicle
with some special sensors that run using VANET infrastructure.
 Smart vehicles are different from the normal vehicles which are fitted with sensors, equipped
with processing and communication abilities that can help users access to services using their
private information, access to information useful for their journeys, doing business
transactions and making decisions.

7.  The third aspect of the VANET
Security R&D Ecosystem is the
Govt. Agencies (GA) that is
responsible for providing
authentication services for
users using secure public and
private keys, whether
permanent or temporary based
on the type of services on
highway.
 GA provides these keys for
secure communications
between vehicles and
infrastructure.

8.  Last aspect of VANET Security R&D Ecosystem is
end users.
 End users have their own security, trust and privacy
requirements

10.  Govt. authority (GA) is the first module of SBC
model and it is responsible to define the
security policies and also authentication
services to secure the public and private keys.
 GA provides these keys for secure
communications between vehicles and
infrastructure.
 Private Trusted Authority (PTA) is also the
part of government authorities and it is
provided different types of service to serve
the users through various types of
applications in heterogeneous environment.

11.  Govt. authorities give more benefits for business parties to invest
their money in this field. Business parties also consider the user
requirements while their journey and provide those services which is
more necessary for end users.
 There are following three basic components of business parties.
Service Provider (SP)
Security Requirements
Difference Services

12.  A smart vehicle has an important role to perform
the secure communication in a network and smart
vehicle is a combination of several mechanical
components with the ability to perform
computations.
 Security is provided by both the hardware and
software working together; however, the most
important role in a smart vehicle is played by the
hardware.
 For secure communication in VANET, the role of
these security hardware modules is very prominent
and has achieved the maximums level of security in
VANET.

14.  End user is the last module of business model
and purpose of this model to provide
entertainments services and makes their
journey more enjoyable.
 With passage of time user requirement will be
change and service provider upgrade their
system and meet end user requirements in
future vehicular network.
 End user has a dynamic behaviour and
changes his/her behaviour according to the
information received from other users or
from the roadside unit (RSU).

15.  Scenario One:
Internet Access
Services

16.  Scenario Two:
Toll Collection
Services

17.  VANET potential applications directly focus
on user’s life on the road by sending some
safety messages and non-safety messages.
 In propose model it is explained three
modules of business model and explain the
relationship of each modules.
 For successful implementation of business
model every module plays their role
accurately and serves the end users.
