Collapse Button Quick Abstract
Modern vehicles are increasingly equipped with highly automated control systems both for driving and for passenger comfort. An integral part of these systems are the communication channels that allow the on-board systems to interact with passenger devices (e.g. tablets), ITS systems (e.g. road-side units), and other vehicles. These advances have significantly enlarged the attack surface and we already have numerous instances of successful penetration of vehicular networks both from inside the vehicle and from the outside. Traditional mechanisms for detecting and responding to such attacks are ill-suited to the vehicular domain mainly due to the fact that the entire process of dealing with an attack must be handled automatically and in a way that does not affect safety or severely impacts the continued availability of the vehicle or its key systems. Once a security breach is suspected, the system must evaluate the circumstances in order to determine whether the threat is real (and not a false positive) and select the optimal response through the use of an Intrusion Response System (IRS). Although IRSs have been adopted in other domains, there is a lack of such systems in the vehicular field. In this paper, we investigate the challenges and requirements for integrating such a mechanism inside a vehicle. In addition, we present an Intrusion Response System based on the Red-Zone principle which meets the identified requirements. Finally, we discuss the integration of IRS through the vehicle system development and the different aspects which support such a process.

Collapse Button Quick Abstract
The Internet evolved from a collection of computers to today’s agglomeration of all sort of devices (e.g. printers, phones, coffee makers, cameras and so on) a large part of which contain security vulnerabilities. The current wide scale attacks are, in most cases, simple replays of the original Morris Worm of the mid-80s. The effects of these attacks are equally devastating because they affect huge numbers of connected devices. The reason for this lack of progress is that software developers will keep writing vulnerable software due to problems associated with the way software is designed and implemented and market realities. So in order to contain the problem we need effective control of network communications and more specifically, we need to vet all network connections made by an application on the premise that if we can prevent an attacker from reaching his victim, the attack cannot take place. This paper presents a comprehensive network security framework, including a well-defined applications programming interface (API) that allows fine-grained and flexible control of network connections. In this way, we can finally instantiate the principles of dynamic network control and protect vulnerable applications from network attacks.

A Policy-based Communications Architecture for Vehicles

Proceedings of ICISSP 2015, ISBN: 978-989-758-081-9

Collapse Button Quick Abstract
Despite the fact that numerous studies have indicated that vehicular networks are vulnerable to external and internal attacks, very little effort has been expended in safeguarding communications both between elements within the vehicle and between the vehicle and the outside world. In this paper we present a mechanism that allows communications policy (essentially who can talk with whom and the security parameters of the channel) to be defined during the design of the software component and then adapted as the component undergoes integration first within subsystems and so on all the way to the final integration in the operational vehicle. We provide a mechanism that can maintain the integrity of the policy throughout the development effort and, finally, enforce the policy during the operation of the component in the production vehicle.

Towards Sentiment-driven Maps Showing Touristic Attractiveness

Collapse Button Quick Abstract
User generated texts on tourism-related social network sites do not only contain factual information, but also valuable opinions and ratings of locations. Nevertheless, most maps on these sites only show markers where something described in a user generated text is located. In particular, no further information is derived from the text and displayed on the maps. Moreover, generalization operations are not employed, although in most cases aggregation and displacement of the user generated content would be necessary to achieve more readable maps. Therefore, we propose a method which automatically creates user-sentiment enriched maps. We use natural language processing tools in order to mine user sentiments for specific places from user generated texts and we propose specially designed point symbols which represent the corresponding mined user sentiment for each location. Additionally, we propose a heuristic, based on Voronoi diagrams, which slightly displaces the aforementioned symbols in case they are very close. This makes the provided map easier to read.

Collapse Button Quick Abstract
In this paper, we present an integrated simulation approach featuring centralized and decentralized traffic management in urban areas. Our aim is to improve traffic flows by dynamic traffic management which is supported by vehicular communication interlinking centralized and decentralized decision making. We focus on traffic state estimation and the optimization of traffic lights as a central component to influence local traffic states, while individual traffic participants’ behavior is modeled by multiagent systems. Traffic participants achieve their individual goals by formation of groups and improving their knowledge about the road network by means of learning. Modeling of vehicular communication takes into account specific characteristics of urban areas, ensuring the realistic collection and dissemination of (de)centralized information. We provide a comprehensive microscopic traffic simulation framework featuring innovative functionality regarding dynamic traffic management, decentralized decision making as well as realistic communication modeling. To illustrate and validate our approach, we present a use case in a city scenario. Simulations are implemented based on the microscopic traffic simulator AIMSUN, which is significantly extended using the AIMSUN API.
