dSDiVN: a distributed Software-Defined Networking architecture for Infrastructure-less Vehicular Networks
In the last few years, the emerging network architecture paradigm of
Software-Defined Networking (SDN), has become one of the most important
technology to manage large scale networks such as Vehicular Ad-hoc Networks
(VANETs). Recently, several works have shown interest in the use of SDN
paradigm in VANETs. SDN brings flexibility, scalability and management facility
to current VANETs. However, almost all of proposed Software-Defined VANET
(SDVN) architectures are infrastructure-based. This paper will focus on how to
enable SDN in infrastructure-less vehicular environments. For this aim, we
propose a novel distributed SDN-based architecture for uncovered
infrastructure-less vehicular scenarios. It is a scalable cluster-based
architecture with distributed mobile controllers and a reliable fall back
recovery mechanism based on self-organized clustering and failure anticipation.Comment: 12 pages, 5 figures, accepted in I4CS201
MARINE: Man-in-the-middle attack resistant trust model IN connEcted vehicles
Vehicular Ad-hoc NETwork (VANET), a novel technology holds a paramount importance within the transportation domain due to its abilities to increase traffic efficiency and safety. Connected vehicles propagate sensitive information which must be shared with the neighbors in a secure environment. However, VANET may also include dishonest nodes such as Man-in-the-Middle (MiTM) attackers aiming to distribute and share malicious content with the vehicles, thus polluting the network with compromised information. In this regard, establishing trust among connected vehicles can increase security as every participating vehicle will generate and propagate authentic, accurate and trusted content within the network. In this paper, we propose a novel trust model, namely, Man-in-the-middle Attack Resistance trust model IN connEcted vehicles (MARINE), which identifies dishonest nodes performing MiTM attacks in an efficient way as well as revokes their credentials. Every node running MARINE system first establishes trust for the sender by performing multi-dimensional plausibility checks. Once the receiver verifies the trustworthiness of the sender, the received data is then evaluated both directly and indirectly. Extensive simulations are carried out to evaluate the performance and accuracy of MARINE rigorously across three MiTM attacker models and the bench-marked trust model. Simulation results show that for a network containing 35% MiTM attackers, MARINE outperforms the state of the art trust model by 15%, 18%, and 17% improvements in precision, recall and F-score, respectively.N/A
