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.

Attacks on Availability in VANET

• DENIAL OF SERVICE (DOS)
• In VANET, DOS shall not be allowed to happen,
  where seamless life critical information must
  reach its intended destination securely and
  timely. In summary, there are three ways the
  attackers may achieve DOS attacks.
• There are three levels of DOS attacks as
  described below.
• Basic Level Overwhelm the Node Resources
• Extended Level Jamming the Channel

VANET Applications and Security Modules

Smart vehicle and Security Hardware Modules

• ? Tamper Proof Device (TPD)
• ? Event Data Recorder (EDR)
• ? Trusted Platform Module (TPM)
• ? Global Position System (GPS)
• ? Radar Systems (RSs)
• ? Communication Facility (CF)
• ? Computing Platform (CP)
• ? Human Machine Interface (HMI)

VANET Security Hardware Modules

Event Data Recorder (EDR)

• Event Data Recorder 7 is non volatile hardware
  module and provides tamper proof storage.
• The purpose of this module is to maintain the log
  of any critical events and later to use this
  information. It is similar to black box used in
  airplane.

21
Temper Proof Device (TPD)

• There are two problems in EDR.
• 1.) it does not generate any data.
• 2.) it does not have any ability to encrypt the
  messages. The researchers added one more module
  to meet these two requirements. The next module
  is Temper Proof Device (TPD).

22
Trusted Platform Module (TPM)

• Trusted Platform Module is a hardware module
  designed for secure computing and can be
  integrated into any device for example in
  notebook.
• TPM is a piece of hardware and need software to
  communicate with it to protect and store data in
  secure location. It can resist software attacks
  but problem is that it cannot control hardware
  tempering.

Analysis of the security modules

Conclusion

• Security is an important issue of VANET as it
  deals with traffic system and human lives
  directly. In near future VANET will be on road
  and their potential applications will be
  providing safety to users.
• In this slide, we presented security requirements
  and then discussed in detail about security
  hardware modules that are used in smart vehicle.
• The lower cost of these modules and their right
  functionality in vehicular environment will make
  the implementation of this technology easier.
