Modern automotive vehicles are becoming a collection of interconnected embedded subsystems, where the mechanical parts are controlled by electronic ones and the vehicle is transformed into a mobile information system. However, the industry standards for in-vehicle communication are not following long-established computer security policies. This trend not only makes vehicles prone to thefts and automated attacks, but also endangers passengers safety. This paper analyzes current practices and standards of the automotive industry, highlighting several vulnerabilities that stress the need to change the way that in-vehicle communication is handled. To this end, we present a novel vehicle security architecture that supports two new features; users with different access rights and roles, and mutual authentication of ECUs. These features can enable a more distributed security architecture and prevent many attacks, or at least trigger adequate alarms to detect and mitigate them, or allow backtracking.

The main purpose of the fault detection and isolation (FDI) function is to maintain the spacecraft (S/C) or any other unnamed aerial vehicle (UAVs) operational and safe (healthy) as required by the mission. Thus, robust FDI is the key property for all aerospace missions and applications, wherever autonomy is of paramount importance. Current work provides a focused insight and lessons learned of the euphoria-filter, a robust H2/H∞ model-based FDI technique, with specific application to the Lisa-Pathfinder thruster failures.

The maritime domain plays a decisive role in the modern worldwide digital economy and collaborative environments. In addition, emerging technologies such as cloud computing provide holistic frameworks for generating and delivering a plethora of interoperable, cost-effective, and scalable e-services that efficiently manage information and data stored inside large-scale datacenters. Driven by this motivation, this article presents a perspective beyond traditional IT utilization over the maritime domain: a roadmap to the Maritime Cloud. The authors define the Maritime Cloud stack and architecture in detail and describe the Maritime Cloud delivery and deployment models as an integral process for transitioning to the Maritime Cloud. The authors evaluate advantages and challenges and present future research directions.

Emerging technologies have become an integral part of our life. Intelligent transportation systems (ITS) is such a set of technologies applied on the transportation domain and considered to be an upcoming dominating technological trend for transportation. Seeking innovative ways for the creation of intelligent and interoperable transportation e/m-services, cooperative-ITS environment provides the possibility to embody and embrace the scalability and extensibility of the web services technology. Driven by this motivation, an interoperable upgrade of the existing ITS-station reference architecture is proposed in the current work. The main scope of the current proposal is the utilisation of an operational model that can implement a service discovery mechanism interconnected with a service registry in the already existing intelligent transportation environment and systems. The operational model functions as the top layer of the ITS reference architecture as already described, so that web services technology and any service oriented architecture could be gradually adopted over the cooperative-ITS and the ITS domain. The scope of current research and proposal is that the entities of the Vehicle ITS-Station to be transformed into autonomous networking nodes over a cooperative and collaborative transportation environment.
