Vehicular Network is an emerging and developing technology to improve traffic management and safety issues, and enable a wide range of value-added services such as collision warning/avoidance. Many applications have been designed to provide safety and comfort for passengers. This technology is a prolific area for attackers who will attempt to challenge the network with their malicious or rational attacks. In this paper we elaborate what a vehicular network is, different kinds of communication in this field, main mechanism and related parts and how vehicular networks work then we introduce some of its applications. After primary familiarity with this system we investigate to different type of attacker, more important security issues, How to secure vehicular networks (security requirements and some tools and methods to achieve secure vehicular networks), difficulties and providing viable security solutions, and at the end briefly explanation of related standards.

Megatrends - Connectivity and Automation Expanding the Boundaries of Personal Mobility: Technology Leadership Brief

2012-10-08
2012-01-9026
Personal mobility is being transformed by the advent of vehicle connectivity and automation. While significant individually, their interrelationships promise to bring unprecedented levels of traffic efficiency. Car-makers are talking about a crash-less society and transportation engineers are talking about the end of congestion - a tall order indeed: can this really be? In this decade we can expect to see the effects of sensor-based active safety systems bringing the crash rate down, as these technologies continue to expand across a wider range of vehicle models. Connectivity for infotainment purposes is already a major market driver, and control assist for convenience purposes is laying the groundwork for semi-automated and automated driving. Direct vehicle-vehicle connectivity opens up new capabilities. What is the government role in these developments - an essential player or a bystander? How can they enable or inhibit market activity in these domains?

Unsettled Topics in the Application of Satellite Navigation to Air Traffic Management

Contemporary air traffic management (ATM) challenges are both (1) acute and (2) growing at rates far outpacing established ways for absorbing technological innovation. Lack of timely response will guarantee failure to meet demands. Immediately that creates a necessity to identify means of coping and judging new technologies based on possible speed of adoption. Paralleling the challenges are developments in capability, both recent and decades old. Some steps (e.g., Global Positioning System (GPS) backup) are well known and, in fact, should have progressed further long ago. Others (e.g., sharing raw measurements instead of position fixes) are equally well known and, if followed by further flight tests initiated (and successful) years ago, would have produced a wealth of in-flight experience by now if development had continued. Other possibilities (e.g., automated pilot override) are much less common and are considered largely experimental.
