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 Applications

• Safety Applications
• Non Safety Applications

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.

SOME NEW POSSIBLE ATTACKS IN VANET

1. Distributed Denial of service (DDOS) Attack

2. Timing Attack in VANET

• Time is a key factor for safety and non safety
  applications
• and users need the right information at the
  right time.
• This attack is a newly addressed problem in which
  an attacker does not disturb the contents of the
  messages.
• The attacker just adds some time slots into the
  original message and creates a delay in the
  original message in this way the user will
  receive the message after its required time.

3. Home Attack

• This is a new type of attack the Internet is one
  of the key
• services that users use during their journey.
• In this attack, an attacker connects with the
  Internet and takes control of the users vehicle
  on the highway.

4. Man in the Middle Attack (MiMA)

• MiMA is a very well known attack in communication
  and can be discussed in a vehicular network where
  the attacker resides between two or more vehicles
  and launches this attack.
• MiMA is active eavesdropping and makes an
  independent connection with the victims vehicle.

5. Traffic Analysis Attack

• The traffic analysis attack is a serious level
  threat to user privacy in vehicular
  communication. A traffic analysis attack is
  against the anonymity of communication between
  vehicle to vehicle (V2V) and vehicle to road side
  unit (V2R).
• In this attack, the attacker defines some goal
  and achieves the goal through capturing different
  types of traffic information packets.
• This includes the location of the user, the
  vehicle ID, the traveling route of the user or
  some other of the users traffic information the
  attacker needs this information to use for its
  attacks.

6. Social Engineering Attack

• In a vehicular network the attacker does not use
  these techniques due to the dynamic behavior of
  vehicles and also users.
• There are some possible cases are considered in
  social engineering in a vehicular network.

14
7. Spamming Attack

• An attacker sends spam messages in a network for
  the purpose of increasing the transmission
  latency and consuming the bandwidth of the
  network.
• With an absence of basic infrastructure and
  centralized administration, it is difficult to
  control this kind of attack.

15
Conclusion

• The applications of vehicular networks are
  important and
• these applications must be secure if attackers
  change the
• content of these applications then the users are
  directly affected by it. It is very difficult to
  monitor the behavior of attackers attackers
  change their attacking behavior and they launch
  different attacks at different times.
• In this paper, only the behavior of attackers and
  some of their possible attacks have been studied.
  Here, only some of the new possible attacks have
  been considered, but the attacker can launch many
  types of attacks and create problems for
  authentic users of a network.
