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.

Attacks Process Mechanism

• Steps
• 1.Attacker launches first class attack to other
  vehicle in the network. E.g. Sybil attack.
• 2. Attacker launches first class attack to
  infrastructure. E.g. DOS attack
• 3. Attacker receives safety message from
  authentic vehicle.
• 4. Attacker receives safety message from
  infrastructure.
• 5. Attacker alters the content of the message and
  passes this message to authentic vehicle.
• 6. Attacker forwards wrong message to
  infrastructure.
• 7. Attacker launches another timing attacks to
  authentic vehicle.
• 8. Attacker launches social attack to near by
  authentic vehicle.
• 9. Attacker monitors the communication between
  the vehicles or infrastructure and achieves
  his/her benefit.

Conclusion

• Users require safety on road in future vehicular
  network. VANET applications must implement
  trusted computing based solution to promote trust
  amongst road users and their vehicles and the
  infrastructure.
• The proposed attacks classes is an initial effort
  to identify various attacks and future research
  works will overcome these issues using trusted
  computing and privacy enhancing technologies.
