Blockchain-based Lightweight Authentication Mechanism for Vehicular Fog Infrastructure
With the increasing development of advanced communication technologies,
vehicles are becoming smarter and more connected. Due to the tremendous growth
of various vehicular applications, a huge amount of data is generated through
advanced on-board devices and is deemed critical to improve driving safety and
enhance vehicular services. However, cloud based models often fall short in
applications where latency and mobility are critical. In order to fully realize
the potential of vehicular networks, the challenges of efficient communication
and computation need to be addressed. In this direction, vehicular fog
computing (VFC) has emerged which extends the concept of fog computing to
conventional vehicular networks. It is a geographically distributed paradigm
that has the potential to conduct time-critical and data-intensive tasks by
pushing intelligence (i.e. computing resources, storage, and application
services) in the vicinity of end vehicles. However secure and reliable
transmission are of significant importance in highly-mobile vehicular networks
in order to ensure the optimal Quality of Service (QoS). In this direction,
several authentication mechanisms have been proposed in the literature but most
of them are found unfit due to absence of decentralization, anonymity, and
trust characteristics. Thus, an effective cross-datacenter authentication and
key-exchange scheme based on blockchain and elliptic curve cryptography (ECC)
is proposed in this paper. Here, the distributed ledger of blockchain is used
for maintaining the network information while the highly secure ECC is employed
for mutual authentication between vehicles and road side units (RSUs).
Additionally, the proposed scheme is lightweight and scalable for the
considered VFC setup. The performance evaluation results against the existing
state-of-the-art reveal that the proposed scheme accomplishes enhanced security
features.Comment: Accepted for publication in IEEE ICC 2019 Workshop on Wireless

Blockchain for the Internet of Vehicles towards Intelligent Transportation Systems: A Survey
Internet of Vehicles (IoV) is an emerging concept that is believed to help
realise the vision of intelligent transportation systems (ITS). IoV has become
an important research area of impactful applications in recent years due to the
rapid advancements in vehicular technologies, high throughput satellite
communication, Internet of Things and cyber-physical systems. IoV enables the
integration of smart vehicles with the Internet and system components
attributing to their environment such as public infrastructures, sensors,
computing nodes, pedestrians and other vehicles. By allowing the development of
a common information exchange platform between vehicles and heterogeneous
vehicular networks, this integration aims to create a better environment and
public space to the people as well as to enhance safety for all road users.
Being a participatory data exchange and storage, the underlying information
exchange platform of IoV needs to be secure, transparent and immutable in order
to achieve the intended objectives of ITS. In this connection, the adoption of
blockchain as a system platform for supporting the information exchange needs
of IoV has been explored. Due to their decentralized and immutable nature, IoV
applications enabled by blockchain are believed to have a number of desirable
properties such as decentralization, security, transparency, immutability, and
automation. In this paper, we present a contemporary survey on the latest
advancement in blockchain for IoV. Particularly, we highlight the different
application scenarios of IoV after carefully reviewing the recent literatures.
We also investigate several key challenges where blockchain is applied in IoV.
Furthermore, we present the future opportunities and explore further research
directions of IoV as a key enabler of ITS.Comment: 28 Pages, 17 Figures, 4 table
