Trust and Trusted Computing in VANET

Trust and Trusted Computing in Vehicular ad hoc
network (VANET)

• Dr I.A.Sumra

Introduction

• Today major concern is to provide safety of users
  and save their lives from tragic road accidents.
• Vehicular Ad hoc Network (VANET) received
  significant attention of researchers and
  automotive industries due to life saving factor.
• Safety and non safety applications running on
  VANET must ensure safety of human life on road
  and applications must be security, trust and
  privacy enhanced to protect road and transport
  users.
• We determined five different classes of attacks
  which need mitigation mechanisms to protect road
  and transport users. Research efforts are being
  conducted to circumvent these attacks.

• 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.

VANET User Requirement (VUR)

• User is the main entity in vehicular work and
  objective of this new technology is to serve
  users and safe their lives from road accidents.
• Safety and non safety VANET applications meet the
  all users requirement during their journey like
  send or receive safety message to other vehicles
  and use the entertainment services.

Levels of Attackers
9
First Level of Attackers

• In first level, the attackers are more seriously
  performed and intensity of the attacks is higher
  as compared to second level.

10
Second Level of Attackers

• Second level attackers also have their own
  severity level which is lower as compared to the
  first level. An attacker in second level is
  outsiders and the basic aim of this kind of
  attacker is to seek their personal benefits.

Vehicular Trusted Computing (VTC)

• Trusted computing is a relatively new technology
  which has gained popularity recently and Trusted
  Computing Group (TCG) 25 has been the main
  proponent of this technology.
• The main aim of TCG is to enhance security in
  computer network by using security hardware
  module (called Trusted Platform Module).

Trusted Entities of VANET

• In this section we will explain six basic
  entities of trust and when all these entities
  work together then will develops a chain of trust
  in the vehicular network.
• Trusted User (TU)
• Trusted Vehicle (TV)
• Trusted Applications (TA)
• Trusted Routing (TR)
• Trusted Medium (TM)
• Trusted Infrastructure (TIF)

Conclusion

• Security of VANET is an important issue to be
  addressed by designers of VANET infrastructure
  security.
• The VANET applications are termed as an important
  solution for the security of the users on the
  road. Moreover it is believed that the Vehicular
  applications must be secured. Because the users
  are directly affected in case the attackers
  change the content of safety applications.
  Attackers change their attacking behavior and
  they launch different attacks at different times.
  Attackers always try to tamper the information
  and create troubles in the network.
• Cryptographic functional components are
  considered as one of key elements for trust
  building and maintaining data integrity in the
  past research work done.
