Summary In intelligent transportation systems, the messages transmitted and received from one vehicle to another vehicle may enhance location privacy scheme; falsification message forwarding collusion attack, timing, and transition attacks all are serious issues and must be addressed in event trust management. Without which, decision making on event message may endanger the whole transportation system and may even threat the human life. In addition, pseudonym expiry is another critical issue of location privacy. The time interval of decision waiting even has been the critical accident response time. In this paper, we proposed a new novel mix zones and dynamic pseudonym trust management system, called MADPTM, which aims to prevent against attackers under privacy‐enhanced road networks. On shortening the pseudonym expiry, we propose dynamic pseudonym trust management system, with the assistance of reported server. We performed a set of simulations under many trust attack models to evaluate the performance and efficiency of the proposed system. Our proposed MADPTM method proved to be highly resilient to various attacks, and simulation results verified that our method outperforms other existing methods.

“…In particular, the attack can be directed to a specific victim, trying to reconstruct its habits or its driving path by analyzing its beacons, or it can be directed to the entire driver community, studying large-scale patterns to predict its behavior. The key to solving this problem is decoupling the ID from the vehicle, which can be achieved by using a pseudonym system [46] that assigns the user a temporary ID and switches it under certain conditions. The conditions required by this strategy are perfectly suited to a parking area: the ID can be randomly switched among a set of cars that wait in a small geographical area for some time.…”

The demand for safe and secure journeys over roads and highways has been growing at a tremendous pace over recent decades. At the same time, the smart city paradigm has emerged to improve citizens’ quality of life by developing the smart mobility concept. Vehicular Ad hoc NETworks (VANETs) are widely recognized to be instrumental in realizing such concept, by enabling appealing safety and infotainment services. Such networks come with their own set of challenges, which range from managing high node mobility to securing data and user privacy. The Software Defined Networking (SDN) paradigm has been identified as a suitable solution for dealing with the dynamic network environment, the increased number of connected devices, and the heterogeneity of applications. While some preliminary investigations have been already conducted to check the applicability of the SDN paradigm to VANETs, and its presumed benefits for managing resources and mobility, it is still unclear what impact SDN will have on security and privacy. Security is a relevant issue in VANETs, because of the impact that threats can have on drivers’ behavior and quality of life. This paper opens a discussion on the security threats that future SDN-enabled VANETs will have to face, and investigates how SDN could be beneficial in building new countermeasures. The analysis is conducted in real use cases (smart parking, smart grid of electric vehicles, platooning, and emergency services), which are expected to be among the vehicular applications that will most benefit from introducing an SDN architecture.

ASPA: Advanced Strong Pseudonym based Authentication in Intelligent Transport System

Intelligent Transport System (ITS) uses the IEEE 802.11P standard for the wireless communication among vehicles. A wireless ad hoc network of vehicles is established to improve road safety, comfort, security, and traffic efficiency. Wireless communication in ITS leads to many security and privacy challenges. Security and privacy of ITS are important issues that demand incorporation of confidentiality, privacy, authentication, integrity, non-repudiation, and restrictive obscurity. In order to ensure the privacy of vehicles during communication, it is required that the real identity of vehicles should not be revealed. There must be robust and efficient security and privacy mechanisms for the establishment of a reliable and trustworthy network. Therefore, we propose Advanced Strong Pseudonym based Authentication (ASPA), which is a distributed framework to handle the security and privacy issues of vehicle communications in ITS. ASPA only allows vehicles with valid pseudonyms to communicate in ITS. Pseudonyms are assigned to vehicles in a secure manner. The pseudonym mappings of vehicles are stored at different locations to avoid any chance of vehicle pseudonyms certificates linkability. In addition, the most recent communication pseudonyms of a malicious vehicle are revoked and are stored in the Certificate Revocation List (CRL) that results in small size of the CRL. Therefore, the CRL size does not increase exponentially. The distributed framework of ASPA guarantees, the vehicles privacy preservation in the real identities mapping and revocation phase. The empirical results prove that ASPA is robust and efficient with low computational cost, overhead ratio, average latency, and an increased delivery ratio.
