“…Vehicular networks comprise of self-organizing nodes whose mobility is constrained by the roads and traffic patterns with dynamic and unstable links between the peers. VANET communications can be either between Vehicle-to-Vehicle (V2V) also known as Inter Vehicular Communication or Vehicle-to-Infrastructure (V2I) [1]. A short to medium range communication service named Dedicated Short Range Communications (DSRC) supports this V2V and V2I communication.…”

Applications in Vehicular Adhoc NETwork (VANET) require high security for end to end communication especially for sensitive information. It is necessary to restrict the unauthorized users from accessing the VANET services using a trusted infrastructure. In addition, messages exchanged should have minimum authentication delay and communication overhead. In this paper, a novel architecture is proposed for trusted infrastructure using combination of short time certificate and Merkle Signature Scheme. In this architecture, secure VANET communication is achieved using psuedo ID generated by the vehicle and the issue of short certificate by the trusted infrastructure that grants the private public key pairs according to the priority of the messages exchanged. Therefore the message dissemination offers reduced overhead and meets the requirement of VANET communication.

“…Vehicles in a VANET authenticate each other by signing every message with their private key, in addition to attaching their certificate before message transmission; receiving vehicles validate this key(s) before it is accepted. To streamline this process, one efficient method that minimize the security overhead is the use of Elliptical Curve Cryptography (ECC) [6] [10]. Nonetheless, as the number of nodes (vehicles, OBUs, RSUs, and traffic lights, etc.)…”

An intelligent transportation system (ITS) is one typical cyber-physical system (CPS) that aims to provide efficient, effective, reliable, and safe driving experiences with minimal congestion and effective traffic flow management. In order to achieve these goals, various ITS technologies need to work synergistically. Nonetheless, ITS's reliance on wireless connectivity makes it vulnerable to cyber threats. Thus, it is critical to understand the impact of cyber threats on ITS. In this paper, using real-world transportation dataset, we evaluated the consequences of cyber threats -attacks against service availability by jamming the communication channel of ITS. In this way, we can have a better understanding of the importance of ensuring adequate security respecting safety and life-critical ITS applications before full and expensive realworld deployments. Our experimental data shows that cyber threats against service availability could adversely affect traffic efficiency and safety performances evidenced by exacerbated travel time, fuel consumed, and other evaluated performance metrics as the communication network is compromised. Finally, we discuss a framework to make ITS secure and more resilient against cyber threats.

“…Beyond the ad-hoc network nature and the requirements of authentication and security, the scheme adds further challenges like ensuring timeliness of data, since delayed, fraudulent or tampered data can result in misguiding commands to the user [159,160]. Moreover, the lack of suitable security features at gateways can be exploited, resulting in loss of controllability and damage to property and life.…”

Modern vehicles represent a complex distributed cyber-physical system that simultaneously handles critical functions like drive-by-wire systems, non-critical functions like window/door control, and compute intensive multimedia functions. Distributed electronic control units (ECUs), which integrate processing elements and supporting peripherals (network interfaces, memory), implement a variety of functions in software, and information is exchanged between ECUs and sensors/actuators over in-vehicle networks. As the complexity of applications rises with increasing automation, extensive hardware support is required in the form of multicore processors or special purpose hardware accelerators to offer required levels of performance. Additional features also drive an increase in the number of ECUs since new functions are rarely consolidated on existing ECUs. Furthermore, network interfaces implemented as ASICs or dedicated logic must be adapted to handle increased communication loads, consuming power and requiring more infrastructure support in terms of cabling and weight. The increasing number of safety-critical functions further impacts complexity if existing one-to-one redundancy schemes are applied. Rising automation also poses news challenges like security, with researchers showing that internal networks are easily manipulated with catastrophic effects and total loss of control. Our research aims to address these challenges using architectural enhancements that are transparent at the computational and network levels, leveraging the capabilities of reconfigurable hardware. We present advanced ECU architectures with extended network capabilities, apply these in the context of safety critical systems, explore ways of extending these schemes to offer advanced security features, and show how such advanced systems can be validated in hardware. Our work represents an advancement in the state of the art with regard to applying FPGAs in vehicular systems.
