Impact of silent period on pseudonym changing protocol

Abstract

The issue of roads, traffic, and ways of regulating them is one of the essential topics in our time. Therefore, vehicle communication systems and networks play a significant role in regulating and safety of traffic and reducing accidents caused by congestion problems and others, not to mention the ability of these systems to provide safe communication of information and data between vehicles. The privacy of the drivers is essential for the success of communication operations. Still, this latter has become the focus of attackers who can obtain information by following several methods and attacks such as locating. As a solution to privacy issues, changing pseudonyms, after silent periods, instead of long-term identifiers is a widely accepted solution. In this thesis, we study the impact of the silent period on the performance of privacy existing schemes. We have considered a privacy dedicated framework, called "Prext" for our study in the vehicular environment. We found different values for the best silent period according to each approach.
