This document outlines classes of attacks in vehicular ad-hoc networks (VANETs) and proposes a solution. It identifies five classes of attacks (network, application, monitoring, social, and timing) that threaten VANET security and safety applications. The document proposes implementing a trusted computing based solution using a trusted security module to promote trust among vehicles, infrastructure, and road users. This would help mitigate the identified attack classes and better protect transport users.

3.  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.

4.  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.

16. 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.

17.  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.
