Title LOCATION PRIVACY AND HIDING USING PSEUDONYM SWAPPING ZONE

Author(s) Ayesha Farid

Abstract The Internet of Vehicles (IoV) is a growing technology that enables seamless communication among vehicles, pedestrians, On-Board Units (OBU), cloud platforms, and Road Side Units (RSU) as vehicles travels. This Intelligent Transport System (ITS) has significantly bolstered road safety, resulting in a marked reduction in road accidents. On one side it offers various advantages but at the same time security issues affects its utility. The proposed Mutual Reporting based Pseudonym Swapping Zone protocol (MR-PSZ) addresses critical challenges in the Internet of Vehicles (IoV), focusing on securing data privacy and efficient pseudonym swap. MR-PSZ introduces an approach where vehicles can exchange pseudonyms in designated zones, enhancing location privacy and minimizing the risk of information exposure to potential attackers. This protocol's main phases include Vehicle Registration, Pseudonym Update, and Pseudonym Swapping, each contributing to the overall goal of improving security and privacy in vehicular communication. The pseudonym swapping phase involves a carefully orchestrated process, ensuring that vehicles can exchange pseudonyms securely in specified areas called pseudonym swapping zones and maintain location privacy. The protocol also considers conditions for successful pseudonym swapping, such as continuous connected time between vehicles and dimension of the pseudonym exchange region. Additionally, proposed scheme emphasizes importance of uploading pseudonym swap logs to the CA after each exchange, enabling the CA to update mappings between real identities and pseudonyms. The proposed scheme is simulated by using SUMO and PREXT tools, the results shows high improvement in terms of anonymity and lowers chances of tracking. The proposed scheme has attained lower attack probability of 10%, followed by 25% by Slotswap, 17% by DPSZ, 55% by PSNV and 62% by DMLP. Similarly during high speed, the traceability factor is reduced to 11.11%, 42.8%, 38.4% and 69.2% than DPSZ, PSNV, SlotSwap and DMLP. During sparse traffic the traceability by adversary is reduced to 23%, 44.4%, 64.28% and 60% than DPSZ, PSNV, SlotSwap and DMLP. Overall, the MR-PSZ protocol contributes in enhancing vehicular network security ensuring data privacy through continuous pseudonym updates, and maintaining data integrity with secure communication and reliable logging. It effectively prevents long-term tracking and unauthorized data tampering, fostering a trustworthy and private vehicular communication environment. This contributes to the advancement of secure, anonymous, and accountable vehicular networks
