Using Trusted Platform Module (TPM) to Secure
Business Communication (SBC) in Vehicular Ad hoc
Network (VANET)

• Dr I.A.Sumra

Introduction

• 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.

FOUR ASPECTS FOR VANET RESEARCH WORK
5
1.Academic Research (AR)

• The first aspect of the VANET Security RD
  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.

2. Car Manufactures (CM)

• The second aspect of the VANET Security RD
  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.

3. Govt. Authorities (GA)

• The third aspect of the VANET Security RD
  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
4. End Users (EU)

• Last aspect of VANET Security RD Ecosystem is
  end users.
• End users have their own security, trust and
  privacy requirements

PROPOSED SBC MODEL
10
1.Govt. Authority (GA)

• 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
2. Business Parties

• 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
3. TPM - Trusted Platform Module

• 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.

4. End User

• 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
WORKING MECHANISM OF SBC

• Scenario One Internet Access Services

16
WORKING MECHANISM OF SBC

• Scenario Two Toll Collection Services

17
Conclusion

• VANET potential applications directly focus on
  users 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.
