Title ANONYMITY ASSURANCE USING EFFICINET PSEUDONYM CONSUMPTION IN INTERNET OF VEHICLES

Author(s) Mehreen Mushtaq

Abstract Internet of vehicles (Iov) is an emerging technology that allows vehicles to travel while communicating with other vehicles, pedestrians, OBU, cloud and RSU. This intelligent transport system (ITS) has increased road safety while road accidents have decreased to a large extent. Through vehicles communication, surrounding vehicles get information about each other’s location, position and velocity to avoid accidents and road congestion. When vehicles travel on roads they share their information with neighbor vehicles through beacon messages that includes their position, speed, acceleration. As this technology is governing, there is a huge security risk that makes the information of vehicles vulnerable. Any adversary after knowing information about vehicles can easily harm vehicles or can use this information for any negative purpose, that’s why security of vehicles is an important concern that cannot be neglected. For security purpose, vehicles change their pseudonym, but only frequently changing pseudonym is not enough because an attacker can link previous pseudonym with new one to get information. To resolve security issues and enhance vehicles anonymity there are many techniques to change pseudonym efficiently but some of them have high pseudonym consumption like Cooperative pseudonym change scheme based on number of neighbors (CPN) and WHISPER. High pseudonym consumption has bad impact upon performance of system and it also disturbs Qos because pseudonym needs high system overhead and memory it also needs that these pseudonym should be authenticated by certificate authority (CA). The proposed solution EPCP has low pseudonym consumption and reduces traceability ratio to maintain anonymity of vehicles. To check the effectiveness of proposed scheme EPCP, OMNet 5.0++, SUMO 0.25.0 and PREXT are used that was built upon Veins 4.4 version. The results showed that proposed scheme EPCP is better in consuming resources and providing protection against adversary attacks.
