Frank Simon, Daniel Simon SQS Software Quality Systems AG, Stollwerckstraße 11, 51149 Cologne, Germany Email: frank.simon|daniel.simon@sqs.com Abstract: New trends in IT industry impose increasingly requirements on openness and interoperability via networks to enterprise software systems. As a consequence, more and more legacy applications are made available via interfaces more openly through mobile and insecure networks, thereby inducing security risks the initial designs have never had to account for. In this paper, we show how a highly automatable black-box method called fuzzing for testing security can be integrated into testing processes to increase interfaces of legacy application in terms of security profiles. tem for mobile communication ­ as example ­ has not only to be tested for its own but might motivate deeper testing of directly connected components. For a more systematic view on these implicit testing adjustments testing can be refined into four steps (a more general approach can be found in [2]: 1. Identification of test objects (What artefacts relevant for project success?) 2. Identification of quality attributes (What properties should the artefacts have?) 3. Determination of corresponding test activities to ensure artefacts having particular attributes 4. Clustering of test activities into test stages that can be executed in conjunction This paper focuses the following aspect: Adding new interfaces creates new test objects as well as it produces new or at least adjusted priorities for quality attributes requiring additional test activities on all test stages. Quality attributes for software can be taken from ISO 25000 family of standards. [3] In particular when adding new service interfaces to legacy applications the first time, security should be seen as one of the top priorities. Security is defined in the ISO 25010 standard as the Degree to which a product or system protects information and data so that persons or other products or systems have the degree of data access appropriate to their types and levels of authorization.

“Good Design is Environmentally-Friendly.” – Discussion of Rams‘ Principle in Context of the Software Life Cycle

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Dieter Rams publicized a statement that good design of products is environmentally friendly. This paper discusses
software, as an intangible product, with environment and terms related to environment. To measure software in context of environment we discuss two accepted methods and show the shortage of these methods in connection with
software. We also mention the analogy between software life cycle and general product life cycle. By considering all
the aspects, we reasoned that ecological design of software is inherently covered by non-functional requirements
which take up product characteristics concerning the whole software life cycle. Finally we discuss if Rams’ statement related to nowadays understanding of environment and propose a revised statement.

GIS-based sales support by company knowledge reuse in the telecommunications sector

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
A quick and timely response to a customer request provides an important competitive advantage for a company. Experience reuse as intended by experience management facilitates an acceleration of the process of preparing offers. From a technology-oriented point of view, experience is \"valuable, stored, specific knowledge that was acquired by a problem solving agent in a problem solving situation\" . In the situation of creating an offer in response to a customer request, such valuable knowledge from a company’s experience might include past prices of products or services for a similar customer request. Especially in the telecommunication market such prices are volatile and depend on many impact factors such as the required technology, bandwidth of available lines, or the time period in which the telecommunication service is required. In the run-up for a large sports event, for instance, purchase prices might be significantly higher than after the event when the investment in new infrastructure has provided additional capacities and when there is less demand.

Dieser Beitrag befaßt sich mit der Integration dynamisch rekonfigurierbarer Architekturen als Funktionseinheiten in RISC Prozessoren mit Befehls-Pipeline. Dabei wird insbesondere auf die Organisation der Konfigurationsdaten sowie die Kontrolle des eigentlichen Rekonfigurationsprozesses eingegangen. Es wird eine Architektur vorgeschlagen, welche leicht in eine Vielzahl von Prozessorarchitekturen integriert werden kann, ohne Änderungen an der Pipelinesteuerung vornehmen zu müssen.

Collusion-secure fingerprint watermarking for real world applications

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Digital transaction watermarking today is a widely accepted mechanism in multimedia security. One major threat on transaction watermarking are collusion attacks. Here multiple individualized copies of the work are mixed to produce a counterfeited or undetectable watermark. One common countermeasure is the usage of so-called fingerprints. Theoretical fingerprint approaches do not consider the inaccuracy of the detection process of watermarking algorithms. In this work we show how an existing fingerprint code can be optimized with respect to code length in order to collaborate with a watermarking algorithm to provide a maximum of reliability with a minimum of payload.

Signaturen stabiler Isotope in landwirtschaftlichen Produkten – Nachweis der Herkunft und des Produktionsverfahrens

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Die Herkunft von Lebensmitteln ist ein wichtiges Kriterium, welches das Kaufverhalten des Verbrauchers maßgeblich beeinflusst. Neben der geographischen Herkunft ist auch das Produktionsverfahren für den Verbraucher von Interesse, und dieses Interesse wird in speziellen Vermarktungswegen genutzt ('Ökologischer Landbau'). Der Nachweis der Authentizität dieser Lebensmittel ist häufig schwierig. In zunehmenden Maße wird die Variabilität ausgewählter stabiler Isotope in den Lebensmitteln als Nachweisverfahren geprüft. In der vorliegenden Studie nutzten wir Unterschiede im 13C-Gehalt von Mais und Gras, um den Einfluss einer Gras- bzw. Mais-Ration während der Endmast auf die C-isotopische Zusammensetzung im Tierkörper zu untersuchen. Weiterhin wird die Variabilität der 13C-Gehalte in Milchinhaltstoffen unterschiedlicher Herkunft dargestellt. Die Ergebnisse zeigen, das ein Nachweis von Mais in ausgewählten landwirtschaftlichen Produkten sicher gelingt.

Der Einsatz von Eyetracking bei der Entwicklung der Online-Version des d2-R

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Der d2 ist ein seit 50 Jahren bewährter psychologischer Papier-und-Bleistift-Test zur Messung der Konzentrationsfähigkeit. Bei der Entwicklung der Online-Version der Revision des d2 (d2-R) mussten wichtige Gestaltungsentscheidungen getroffen werden. Wie ist die Instruktion zu gestalten, wenn kein Testleiter zur Verfügung steht? Wie kann erreicht werden, dass das Testmaterial wie in der Papierbedingung abgearbeitet wird? Wie ist das Zeitlimit zu setzen, damit sehr fähige Personen an ihre Grenze stoßen? In einem Usability-Test mit einem High-Fidelity-Prototypen wurden Antworten auf diese Fragen erarbeitet, indem Screencasts mit synchronen Blickortüberlagerungen qualitativ analysiert wurden. Die Ergebnisse werden anhand von Highlightvideos und Frame-by-frame-Animationen präsentiert und zur Diskussion gestellt.

Unternehmen des Maschinen- und Anlagenbaus sind bestrebt, Entwicklungs- und Inbetriebnahme-zeiten für Anlagen zu reduzieren und damit den Absatz zu erhöhen. Der Steuerungscode dieser Anlagen wird typischerweise nicht auf Basis anerkannter Softwaretechnik-Methoden entwickelt und nur unsystematisch per Copy & Paste wiederverwendet. Die Anwendung von moderner Software-technik und insbesondere die modellgetriebene Entwicklung bergen daher ein großes Potential für die Steigerung der Qualität und Effizienz. Allerdings meiden Unternehmen die damit verbundene Komplexität und Investitionskosten. Wir präsentieren ein Stufen-Modell für die Verbesserung der Softwareentwicklung, das leichter von Unternehmen adaptierbar ist und berichten von unseren Erfahrungen mit dem Industriepartner Venjakob bei dessen Anwendung.

Networks are a critical factor in the performance of a modern company. Managing a network is as important as managing any other aspect of a company's performance and security. There are many tools and appliances for monitoring the traffic and analyzing the security aspects of the network flows. They are using different approaches and they rely on different characteristics of the network flows. The network researchers are still working on a common approach for security baselining that might enable early alerts. This paper is focusing on the security baselining based on a simple flow analysis utilizing the flows measurements and the theory of the Markov models.

Survey: Artificial Intelligence, Computational Thinking and Learning

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Learning is central to both artificial intelligence and human intelligence, the former focused on understanding how machines learn, the latter concerned with how humans learn. With the growing relevance of computational thinking, these two efforts have become more closely connected. This survey examines these connections and points to the need for educating the general public to understand the challenges which the increasing integration of AI in human lives pose. We describe three different framings of computational thinking: cognitive, situated, and critical. Each framing offers valuable, but different insights into what computational thinking can and should be. The differences between the three framings also concern the views of learning that they embody. We combine the three framings into one framework which emphasizes that (1) computational thinking activities involve engagement with algorithmic processes, and (2) the mere use of a digital artifact for an activity is not sufficient to count as computational thinking. We further present a set of approaches to learning computational thinking. We argue for the significance of computational thinking as regards artificial intelligence on three counts: (i) Human developers use computational thinking to create and develop artificial intelligence systems, (ii) understanding how humans learn can enrich artificial intelligence systems, and (iii) such enriched systems will be explainable. We conclude with an introduction of the articles included in the Special Issue, focusing on how they call upon and develop the themes of this survey.
