RIN: A dynamic pseudonym change system for privacy in VANET

Abstract

Summary We propose in this paper a security protocol based on a dynamic change of pseudonym for privacy and anonymity in Vehicular Ad hoc NETworks (VANET). Our proposal ensures privacy for the driver and his vehicle whether he is the transmitter or receiver of the message. By handling all possible cases of changes in vehicles behavior during traffic, we ensure a safe and secure traffic management. We built the architecture of our solution on three essential entities designed for VANET: a trusted authority, a Road Side Unit, and vehicles. Our pseudonym change system ensures anonymity at any time, anywhere, with any speed of a vehicle, in all directions of a vehicle, in any environment (highway or urban), with any traffic density, independently of neighboring vehicles, and changes in vehicles behavior. In three steps, anonymity, integrity, and confidentiality are guaranteed by our RIN (Real Initial New) protocol. Our protocol blocks attacks as DOS and Sybil. Results obtained by the simulations show the efficiency of our solution. Compared with other relevant approaches from the literature, the results confirm the credibility of our protocol regarding to the privacy assurance in VANET.

A Systematic Literature Review on Security of Vehicular Ad-Hoc Network (VANET) Based on VEINS Framework

“…• Privacy: A safety-aware location privacy-preserving scheme was proposed to adjust the vehicle's communication area to prevent continuous location monitoring [52]. A security protocol according to a pseudonym dynamic change for anonymity and privacy to ensure privacy for the driver and his/her vehicle whether he/she is the sender or receiver of the message [53]. A set enhancement of schemes to allow vehicles to adjust their beacon communication area to conditionally avert tracking [54].…”

Anonymity Assurance Using Efficient Pseudonym Consumption in Internet of Vehicles

“…This technique has higher protection against linking attacks, and more schemes need to be added for increasing confusion for an adversary. In [19], the technique uses three types of pseudonyms including real, initial and new pseudonyms produced by the TA, RSU and onboard unit (OBU), correspondingly. Each pseudonym is allocated to vehicles before the authentication of the previous one.…”

Foreword to the Special Issue on the 2017 Edition of the Workshop on Performance Evaluation of communications in DIstributed Systems and WEb‐based Service Architectures (PEDISWESA 2017)

“…Bouksani and Bensaber propose a security protocol based on a dynamic change of pseudonym for privacy and anonymity in Vehicular Ad hoc NETworks (VANET) that ensures privacy for the driver and his vehicle in any environment (highway or urban) and under different conditions (traffic density, independently of neighboring vehicles, and changes in vehicles behavior). The proposed solution is also able to comply with Denial Of Service (DOS) and Sybil attacks.…”
