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.

VANET Security Requirements

• Vehicular network applications require security
  and the objective of these applications is to
  serve users and make their journey secure and
  comfortable.
• Attackers have their own role in this network and
  we cannot predict the dynamic behavior of the
  attacker. If an attacker works on a safety
  application and changes the content of the safety
  message then it poses a very difficult condition
  on the road and many users will be affected due
  to this kind of attack.
• Accidents are often the result of an alteration
  of any safety message or the sending of even one
  wrong safety message in a network and many human
  lives are at risk 1.

Conclusion

• In trusted vehicular networks, trust and security
  are two key
• requirements for users. While privacy is a basic
  necessary
• requirement for security in life saving vehicular
  networks, a
• guarantee that not only the vehicle platform but
  also the
• infrastructure can be trusted is also vital.
• When users receive any safety message in
  vehicular communications, it is important that
  the message is authentic and that the source
  making the request is legitimate. A new and
  practical cardbased scheme has been proposed in
  this paper to make possible the trusted
  authentication of users while enabling various
  transactions with a Vehicle Service Provider
  (VSP).
