Abstract [en]

Vehicular Communication (VC) network technology is in the verge of real world

deployment. The technology is aimed at achieving high levels of traffic efficiency

security and comfort for the users of the traffic system. The technology

facilitates exchange of awareness and notification messages among the vehicles

to improve the traffic efficiency and safety of the drivers. However, deployment

of this awesome technology faces several security and privacy risks. The

system is subjected to security risks like replay attacks, nodes sending false

information to the system, denial of service attacks by clogging the networks.

System also faces several privacy challenges in which sensitive user data can

be eavesdropped and also tracing out a particular node using the location data

sent by the node. In this research we focused on protecting the privacy of

the users using the VC system. Several European projects have been working

on privacy enhancement techniques for VC environments. Privacy policy

enforcement approach from Privacy Enabled Capability In Co-Operative Systems

and Safety Applications (PRECIOSA), pseudonym approach from Secure

Vehicular Communication (SeVeCom) and Preparing secure V2X Communication

Systems (PRESERVE) project which integrates the results from both PRECIOSA

and SeVeCom projects are three of those projects considered in this report. This

research is more focused on the pseudonym approach proposed by SeVeCom.

We discuss the impact of pseudonym change on the communication stack, what

other lower layer identifiers need to be changed along with the pseudonym

change, and is there any other ways the attacker can still link the messages

from a particular node to hamper the nodes privacy. Finally after analyzing the

results from the research, we propose a solution to include a new module in the PRESERVE

architecture called Identifier Change Management (IDCM) module to

improve the anonymity of the user participating in the vehicular communication.
