A deployment of the Vehicle-to-Vehicle communication technology according to ETSI is in preparation in Europe. Currently, a Public Key Infrastructure policy for Intelligent Transport Systems in Europe is in discussion to enable V2V communication. This policy set aside two classes of keys and certificates for ITS vehicle stations: long term authentication keys and pseudonymous keys and certificates. We show that from our point of view the periodic sent Cooperative Awareness Messages with extensive data have technical limitations and together with the pseudonym concept cause privacy problems.
The latest advances in the field of smart card technologies allow modern cards to be more than just simple security tokens. Recent developments facilitate the use of interactive components like buttons, displays or even touch-sensors within the card's body thus conquering whole new areas of application. With interactive functionalities the usability aspect becomes the most important one for designing secure and popularly accepted products. Unfortunately, the usability can only be tested fully with completely integrated hence expensive smart card prototypes. This restricts severely application specific research, case studies of new smart card user interfaces and the optimization of design aspects, as well as hardware requirements by making usability and acceptance tests in smart card development very costly and time-consuming. Rapid development and simulation of smart card interfaces and applications can help to avoid this restriction. This paper presents a rapid development process for new smart card interfaces and applications based on common smartphone technology using a tool called SCUID^Sim. We will demonstrate the variety of usability aspects that can be analyzed with such a simulator by discussing some selected example projects.
Secure vehicular communication has been discussed over a long period of time. Now,- this technology is implemented in different Intelligent Transportation System (ITS) projects in europe. In most of these projects a suitable Public Key Infrastructure (PKI) for a secure communication between involved entities in a Vehicular Ad hoc Network (VANET) is needed. A first proposal for a PKI architecture for Intelligent Vehicular Systems (IVS PKI) is given by the car2car communication consortium. This architecture however mainly deals with inter vehicular communication and is less focused on the needs of Road Side Units. Here, we propose a multi-domain PKI architecture for Intelligent Transportation Systems, which considers the necessities of road infrastructure authorities and vehicle manufacturers, today. The PKI domains are cryptographically linked based on local trust lists. In addition, a crypto agility concept is suggested, which takes adaptation of key length and cryptographic algorithms during PKI operation into account.
Wer heute eine beliebige Publikumszeitschrift durchblättert, wird regelmäßig auf Inhalte und Beilagen (z.B. CD-ROM) stoßen, die vor allem dem Interesse von Anzeigenkunden oder Vertriebspartnern dienen und dennoch als redaktionelle Dienstleistung erscheinen. Im Fernsehen haben wir uns an vielfältige Medien- und Produktpartnerschaften gewöhnt, bei denen sich journalistische und werbliche Ziele unauflösbar vereinen. So werden beliebte TV-Sendungen durch eine umfangreiche Begleitpublizistik oder durch Merchandising-Produkte weit über das Fernsehpublikum hinaus vermarktet. In den neuen Online-Medien (Online-Dienste und WWW) schließlich ist es gang und gäbe, dass redaktionelle und kommerzielle Angebote auf identischen Webseiten erscheinen, weil die Bewertung und der Verkauf von Gütern und Dienstleistungen hier ohne Medienwechsel möglich sind. Ist es angesichts dieser Entwicklungen noch sinnvoll, auf einer Trennung von Werbung und Programm zu bestehen, wie sie das Pressegesetz allen an die allgemeine Öffentlichkeit gerichteten Medien vorschreibt?

Rehabilitation wirkt
(2014)
Die medizinische Rehabilitation bildet im bundesdeutschen Gesundheitssystem eine wichtige Säule. Sie wird weltweit immer wieder als vorbildlich angesehen und ist im internationalen Vergleich mit Mitteln, Infrastruktur, Know-how und Behandlungsqualität hervorragend ausgestattet. Dies ist gut so, aber ist es gut genug?
This book constitutes the thoroughly refereed post-conference proceedings of the 15th International Conference on Smart Card Research and Advanced Applications, CARDIS 2016, held in Cannes, France, in November 2016. The 15 revised full papers presented in this book were carefully reviewed and selected from 29 submissions. The focus of the conference was on all aspects of the design, development, deployment, validation, and application of smart cards or smart personal devices.
Unternehmen stehen oft vor der Frage, nach welchen Kriterien Investitionsentscheidungen in anderen Ländern und an ausländischen Standorten – ggf. im Wettbewerb zu anderen Geografien – zu treffen sind. Aufgrund der schwierigen Revidierbarkeit von Standortentscheidungen ist zu erwarten, dass die Unternehmen eine Vielzahl von Kriterien in ihre Überlegungen einbeziehen und die in Betracht kommenden Standorte diesbezüglich komparativ prüfen.
The MAP-Elites algorithm produces a set of high-performing solutions that vary according to features defined by the user. This technique has the potential to be a powerful tool for design space exploration, but is limited by the need for numerous evaluations. The Surrogate-Assisted Illumination algorithm (SAIL), introduced here, integrates approximative models and intelligent sampling of the objective function to minimize the number of evaluations required by MAP-Elites.
The ability of SAIL to efficiently produce both accurate models and diverse high performing solutions is illustrated on a 2D airfoil design problem. The search space is divided into bins, each holding a design with a different combination of features. In each bin SAIL produces a better performing solution than MAP-Elites, and requires several orders of magnitude fewer evaluations. The CMA-ES algorithm was used to produce an optimal design in each bin: with the same number of evaluations required by CMA-ES to find a near-optimal solution in a single bin, SAIL finds solutions of similar quality in every bin.
Embodied artificial agents operating in dynamic, real-world environments need architectures that support the special requirements that exist for them. Architectures are not always designed from scratch and the system then implemented all at once, but rather, a step-wise integration of components is often made to increase functionality. Our work aims to increase flexibility and robustness by integrating a task planner into an existing architecture and coupling the planning process with the preexisting execution and the basic monitoring processes. This involved the conversion of monolithic SMACH scenario scripts (state-machine execution scripts) into modular states that can be called dynamically based on the plan that was generated by the planning process. The procedural knowledge encoded in such state machines was used to model the planning domain for two RoboCup@Home scenarios on a Care-O-Bot 3 robot [GRH+08]. This was done for the JSHOP2 [IN03] hierarchical task network (HTN) planner. A component which iterates through a generated plan and calls the appropriate SMACH states [Fie11] was implemented, thus enabling the scenarios. Crucially, individual monitoring actions which enable the robot to monitor the execution of the actions were designed and included, thus providing additional robustness.
