    GeoBox: Design and Evaluation of a Tool for Resilient and Decentralized Data Management in Agriculture

    Farm Management Information Systems (FMIS) are an important core component of modern farming companies as they allow, e.g., to document activities, create fertilization plans, and feed digital equipment with required data. Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.

    When considering privacy, context, and environmental circumstances can have a strong influence on individual decisions and user behavior. Especially in crises or threatening situations, privacy may conflict with other values, such as personal safety and health. In other cases, personal or public safety can also be dependent on privacy: the context of flight shows how, for those affected, the value of data protection can increase as a result of an increased threat situation. Thus, when individual sovereignty—the autonomous development of one’s own will—or safety is highly dependent on information flows, people tend to be more protective of their privacy in order to maintain their information sovereignty. But also, the context of agriculture, as part of the critical infrastructure, shows how privacy concerns can affect the adoption of digital tools. With these two examples, flight and migration as well as agriculture, this chapter presents some exemplary results that illustrate the importance of the influence of situational factors on perceived information sovereignty and the evaluation of privacy.

    SCAtt-man: Side-Channel-Based Remote Attestation for Embedded Devices that Users Understand

    From the perspective of end-users, IoT devices behave like a black box: As long as they work as intended, users will not detect any compromise. Users have minimal control over the software. Hence, it is very likely that the user misses that illegal recordings and transmissions occur if a security camera or a smart speaker is hacked. In this paper, we present SCAtt-man, the first remote attestation scheme that is specifically designed with the user in mind. SCAtt-man deploys software-based attestation to check the integrity of remote devices, allowing users to verify the integrity of IoT devices with their smartphones. The key novelty of SCAtt-man resides in the utilization of user-observable side-channels such as light or sound in the attestation protocol. Our proof-of-concept implementation targets a smart speaker and an attestation protocol that is based on a data-over-sound protocol. Our evaluation demonstrates the effectiveness of toolname against a variety of attacks and its usability based on a user study with 20 participants.

    Eine Klassifikation sicherheitskritischer UX-Design-Patterns

    User Experience ist von zunehmender Relevanz für die Entwicklung digitaler Designentscheidungen und hat somit weitgehende Auswirkungen auf das Nutzerverhalten. Dass dies besonders für die Sicherheit und Vertraulichkeit nicht nur von Vorteil sein kann, sondern Nutzer*innen negativ beeinflussen kann, wird in dieser Arbeit ersichtlich. Betrachtetwerden dafür die Themengebiete Anti-Patterns, Grey Patterns und Dark-Patterns. Anti-Patterns bezeichnen wiederkehrende Lösungen für ein Konzept eines User Interfaces, die trotz guter Intention ungewünschte Nebeneffekte oder Konsequenzen haben. Dark-Patterns dagegen stellen Designentscheidungen dar, die durch Täuschung oder Ausnutzung psychischen Drucks versuchen Nutzer*innen zu Handlungen zu verleiten, von denen die Ersteller*innen des Dark-Patterns mehr profitieren als die Anwender* innen. Der Begriff Grey Patterns wird in dieser Arbeit für alle Design Patterns genutzt, die sich nicht direkt zuordnen lassen. Da es bisher kaum vergleichendeWerke und keinen Konsens zu diesen Themengebieten gibt, ist das Ziel dieser Arbeit ein grundlegendes Modell aufzustellen. Dabei wird durch die Untersuchung bestehender Literatur eine zusammenfassende Taxonomie und ein Vorgehen zur Unterscheidung von Anti-Patterns und Dark-Patterns erarbeitet, die als Grundlage für weitere Arbeiten und zur Entwicklung von Gegenmaßnahmen genutzt werden können.

    Supporting Users in Data Disclosure Scenarios in Agriculture through Transparency

    Business collaboration in the era of digital transformation requires the exchange of operational data. Since data are hardly controllable once they have been published or shared with others, it is highly important that users are clearly informed about who has access to which data and how certain settings can prevent the disclosure of sensitive data. However, giving end users more control over their data through increased transparency could also lead to information overload. This is particularly true in the field of agriculture, where tight schedules put pressure on employees of small enterprises. We conduct an empirical prestudy with 52 German farmers to investigate current data sharing scenarios. From these insights, we derive requirements and a concept for data sharing solutions providing data flow transparency for users. To investigate the behavior of users and the effects of transparent UI controls, we evaluate a prototype with 18 persons. Our evaluation shows that farmers demand flexible and secure tools that adjust to their workflows. Also, data should be stored and processed locally, granting farmers data sovereignty. Although the controls require additional effort, the evaluated transparent controls for data disclosure are easy to use and raise user awareness.

    LoRaWAN Security Issues and Mitigation Options by the Example of Agricultural IoT Scenarios
    Transactions on Emerging Telecommunications Technologies (ETT) ;33(5):e4452. doi:10.1002/ett.4452
    [BibTeX] [Abstract] [Download PDF]

    The Internet of Things (IoT) is a major trend that is seen as a great opportunity to improve efficiency in many domains, including agriculture. This technology could transform the sector, improving the management and quality of agricultural operations, for example, crop farming. The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.

    Resilience in Agriculture: Communication and Energy Infrastructure Dependencies of German Farmers

    Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.

    The Role of Privacy in Digitalization – Analysing the German Farmers‘ Perspective

    Technological progress can disrupt domains and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk. Having insight into the business data of others along the supply chain provides an advantage in terms of market position. This is particularly true in agriculture, where there is already a significant imbalance of power between actors. A multitude of small and medium-sized farming businesses are opposed by large upstream and downstream players that drive technological innovation. Further weakening the market position of farmers could lead to severe consequences for the entire sector. We found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other hand, privacy itself influences adoption of digital tools. Our study sheds light on the emerging challenges for farmers and the role of privacy in the process of digitalization in agriculture.

    Low Power Wide Area Networks (LPWAN) für krisentaugliche Datenübertragung in landwirtschaftlichen Betrieben
    41. GIL-Jahrestagung: Informatik in der Land-, Forst- und Ernährungswirtschaft Meyer-Aurich, Andreas Gandorfer, Markus Hoffmann, Christa Weltzien, Cornelia Bellingrath-Kimura, Sonoko D. Floto, Helga.
    [BibTeX] [Abstract] [Download PDF]

    Zuverlässige IT-basierte Kommunikation in der Landwirtschaft wird immer wichtiger für den regulären Betriebsablauf. Sollte sich ein Landwirt beispielsweise während eines lokalen Krisenfalls, wie einem Ausfall des Mobilfunknetzes oder des Internetzugangs des Betriebs, auf dem Feld aufhalten, wird ein alternativer Kommunikationskanal benötigt, um weiterhin eine Verbindung zu IT-Komponenten und benötigten Daten herstellen zu können. Mit der zunehmenden Digitalisierung finden Low-Power-Wide-Area-Network (LPWAN)-Technologien immer häufiger Anwendung, beispielsweise durch den Aufbau von Sensornetzwerken. Die eingesetzten LPWANTechnologien bieten dabei eine hohe Reichweite und sind größtenteils autark einsetzbar, erlauben jedoch keine klassische TCP/IP-Kommunikation. Im Rahmen dieser Arbeit wird experimentell eine populäre LPWAN-Technologie, namentlich LoRaWAN, durch AX.25 auf OSI-Schicht 2 (Data Link Layer) ergänzt, um Endgeräten eine TCP/IP-basierte Kommunikation über weite Strecken zu erlauben. Die Evaluation zeigt, dass klassische Anwendungen mit niedriger Bandbreite somit funktionsfähig sind und krisentaugliche Datenübertragung in landwirtschaftlichen Betrieben ermöglichen können.

    abstract = {Zuverlässige IT-basierte Kommunikation in der Landwirtschaft wird immer wichtiger für den regulären Betriebsablauf. Sollte sich ein Landwirt beispielsweise während eines lokalen Krisenfalls, wie einem Ausfall des Mobilfunknetzes oder des Internetzugangs des Betriebs, auf dem Feld aufhalten, wird ein alternativer Kommunikationskanal benötigt, um weiterhin eine Verbindung zu IT-Komponenten und benötigten Daten herstellen zu können. Mit der zunehmenden Digitalisierung finden Low-Power-Wide-Area-Network (LPWAN)-Technologien immer häufiger Anwendung, beispielsweise durch den Aufbau von Sensornetzwerken. Die eingesetzten LPWANTechnologien bieten dabei eine hohe Reichweite und sind größtenteils autark einsetzbar, erlauben jedoch keine klassische TCP/IP-Kommunikation. Im Rahmen dieser Arbeit wird experimentell eine populäre LPWAN-Technologie, namentlich LoRaWAN, durch AX.25 auf OSI-Schicht 2 (Data Link Layer) ergänzt, um Endgeräten eine TCP/IP-basierte Kommunikation über weite Strecken zu erlauben. Die Evaluation zeigt, dass klassische Anwendungen mit niedriger Bandbreite somit funktionsfähig sind und krisentaugliche Datenübertragung in landwirtschaftlichen Betrieben ermöglichen können.},

    Erfolgsorientierte Dienstleistung: Neue Perspektiven für die landwirtschaftliche Arbeitsteilung durch hybride Dienstleistungen
    41. GIL-Jahrestagung: Informatik in der Land-, Forst- und Ernährungswirtschaft .
    [BibTeX] [Abstract] [Download PDF]

    Im Projekt HyServ werden landwirtschaftliche Dienstleistungen als Hybrid aus klassischem Arbeitsauftrag und Auftrag zur Datenverarbeitung verstanden, der sowohl den Auftrag als auch das Ergebnis umfasst. Die hybriden Dienstleistungen mit fälschungssicheren Vereinbarungen und technischen Kontrollmöglichkeiten sichern besseres Vertrauen in intensiven Datenaustausch und innovative Produktionsformen in komplexen Kooperationen. Die integrierte Betrachtung von konventionell-physischer Arbeitsleistung und Datenverarbeitung erlaubt neuartige landwirtschaftliche Dienstleistungen: Anstelle der reinen Aktivität kann das Erreichen definierter Ziele vereinbart und nachprüfbar dokumentiert werden. So können auch Ergebnisse, die erst nach längerer Zeit erkennbar werden, in die vereinbarte Leistung einbezogen und erfolgsabhängig entlohnt werden. Derartige erfolgsorientierte Dienstleistungen verbinden Ausführung und Garantieleistungen und eröffnen so gerade in kritischen Zeiten neue Formen der Risikoverteilung und innovativer Geschäftsmodelle.

    Vulnerability Assessment in the Smart Farming Infrastructure through Cyberattacks

    The Internet of Things (IoT) has a significant impact on agriculture. So-called Smart Farming uses drones and a variety of sensors to measure climate, irrigation, soil moisture or GPS position. With this rapid influx of technology increases the threat that vulnerabilities in those technologies are being exploited for malicious intent. To show the impact of cyberattacks on agriculture, we present a simulation of several attacks on a ZigBee-based wireless sensor network. We conduct a delay attack, an interference attack and three different routing attacks (sinkhole, blackhole and selective forwarding attack). Those attacks are simulated using NETA with the OMNET++ framework. We will show that the security of WSN is influenced by factors like energy consumption or computation power, which can conflict with other interests like low per-unit costs.

    Digitalization, which proceeds in all branches, as well in agriculture, by using new technology, sensors and networking, requires responsible usage of data. One possibility to manage data and use them to create value is the blockchain-technology. It is primary enforced by the food industries and consumers to ensure traceability and transparency. To put blockchain-technology into beneficial use in agriculture, this domain has to be analyzed regarding social and business aspects. This paper presents the results of a qualitative study where 41 actors from the agricultural do-main participated in focus groups and delivered a written statement. It was found that farmers are interested in adapting new markets and technologies early to get an economic advantage. On the other hand, the fear of losing traditional local business partners and the social surroundings of the farmers must be considered

    Hybride Dienstleistungen in digitalisierten Kooperationen in der Landwirtschaft

    Arbeitsteilung und Kooperation sind essentielle Bestandteil von Landwirtschaft, die sich im Laufe der Geschichte stetig weiterentwickelt haben. Nun ermöglicht die voranschreitende Digitalisierung in der Landwirtschaft erneut Innovationen und neue Arten der Kooperation. Moderne Dienstleistungen – wie optimierte Logistik oder umweltschonende Bewirtschaftung – verbinden zunehmend Maschinenleistungen und Datendienste zu untrennbaren Hybriden Services. Im Zuge dessen werden detaillierte Vereinbarungen bezüglich der bereitzustellenden betrieblichen Daten sowie der Verwendung der während der Dienstleistung erhobenen Messwerte getroffen. Im Rahmen des Projektes HyServ werden Servicekonzepte und Schnittstellen entwickelt, welche es den Akteuren erlauben, die Hoheit über die eigenen Daten zu behalten und dennoch kooperative Dienstleistungsverträge zu erstellen. Zu diesem Zweck werden dezentrale Strukturen mit kryptographisch gesichertem Austausch etabliert, welche als Infrastruktur für orchestrierte Micro-Services und Smart Contracts dienen.
