abstract = {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.},

abstract = {Information and Communication Technology (ICT) is vital for everyday life and especially during times of disaster.Relying on existing infrastructure is problematic as maintenance is expensive, and they can be disrupted in emergency scenarios. Cost is a major factor which limits the technologies that can be used in rural areas or for emergency response, as satellite uplinks or private cellular networks are very expensive and complex. LoRa is commonly used for IoT infrastructure worldwide in the form of LoRaWAN to cover larger distances with low costs. But it can also be used in a Device-to-Device (D2D) mode for direct communication. By combining LoRa with Disruption-tolerant Networking (DTN), we present an affordable and practical solution that can cope with challenging conditions and be used for a large variety of applications. In our evaluation, we show how adaptable our solution is and how it outperforms similar mesh-based applications for disaster communication.},

abstract = {Landwirtschaft als essenzieller Teil der Nahrungsmittelproduktion gehört zu den kritischen Infrastrukturen (KRITIS). Dementsprechend müssen die eingesetzten Systeme für einen widerstandsfähigen Betrieb ausgelegt sein. Dies gilt auch für die auf landwirtschaftlichen Betrieben eingesetzte Software, die Sicherheits- und Resilienzkriterien genügen muss. Jedoch ist die Zunahme an Software zu beobachten, welche eine permanente Internetkonnektivität erfordert, d. h. eine stabile Verbindung zu Servern oder Cloud-Applikationen ist für deren Funktionsweise erforderlich. Dies stellt eine erhebliche Schwachstelle hinsichtlich der Resilienz dar und kann bei Ausfällen der Telekommunikationsinfrastruktur zu großen Problemen führen. Mit Entwicklungen aus dem Bereich Resilient Smart Farming (RSF) zeigen wir, wie Datenhaltung nach dem Offline-First-Prinzip gestaltet werden kann. Ein zentraler Bestandteil hierbei ist das Resilient Edge Computing (REC) und die entwickelte HofBox: ein Mini-Server, der das Datenmanagement im Betrieb übernimmt und mittels innovativer Open-Source basierender Container-Technologie (Open Horizon) umsetzt. Dadurch werden in Zukunft weitere Anwendungsfälle innerhalb der landwirtschaftlichen Produktions- und Wertschöpfungskette durch Public-Private-Partnership-Modelle realistisch und realisierbar.},

Both technical and non-technical research-related risks are analyzed, paying attention to research ethics, data security, and privacy. We argue that any threat model and risk analysis is highly context-dependent. Our analysis reveals that in certain research processes, human security does not necessarily coincide with data security and that an ambivalence exists between privacy and usability. In addition to the concrete threat analysis, the paper identifies some general technical solutions (e.g., encryption methods, communication software) for different research steps to foster secure and ethically justifiable research.},

abstract = {We present an approach to enable long-range device-to-device communication between smartphones in crisis situations. Our approach is based on inexpensive and readily available microcontrollers with integrated LoRa hardware that we empower to receive and forward messages via Bluetooth, Wi-Fi, or a serial connection by means of a dedicated firmware, called rf95modem. The developed firmware cannot only be used in crisis scenarios but also in a variety of other applications, such as providing a communication fallback during outdoor activities, geolocation-based games or broadcasting of local information. We present two applications to show the benefits of our approach. First, we introduce a novel device-to-device LoRa chat application that works on both Android and iOS as well as on traditional computers like notebooks using a console-based interface. Second, we demonstrate how other infrastructure-less technology can benefit from our approach by integrating it into the DTN7 delay-tolerant networking software. Furthermore, we present the results of an in-depth experimental evaluation of approach consisting of (i) real-world device-to-device LoRa transmissions in urban and rural areas and (ii) scalability tests based on simulations of LoRa device-to-device usage in a medium-sized city with up to 1000 active users. The firmware, our device-to-device chat application, our integration into DTN7, as well as our code fragments of the experimental evaluation and the experimental results are available under permissive open-source licenses.},

abstract = {Low Power Wide Area Network (LPWAN) technologies are typically promoted for Internet-of-Things (IoT) applications, but are also of interest for emergency communications systems when regular fixed and mobile networks break down. Although LoRaWAN is a frequently used representative here, there are sometimes large differences between the proposed range and the results of some practical evaluations. Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values. Nevertheless, the results certify that LoRaWAN technology has a high range that cannot be achieved with other common technologies for emergency communications.},

abstract = {Since communications infrastructure is subject to many impacts, e.g., destructive natural events, they can potentially collapse at any time. Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

abstract = {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.},

abstract = {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.},

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.},

abstract = {Reliable IT-based communication in agriculture is becoming increasingly important for regular operations. For example, if a farmer is in the field during a network outage, such as a failure of the mobile network, an alternative communication channel is needed to continue to connect to IT components and required data. With increasing digitalization, Low Power Wide Area Network (LPWAN) technologies are being used more and more frequently, e.g. for sensor networks. The LPWAN technologies offer a high range and can be used autonomously for the most part, but do not allow classic TCP/IP communication. In this work, a popular LPWAN technology, namely LoRaWAN, is experimentally supplemented by AX.25 on OSI layer 2 (Data Link Layer) to allow end devices TCP/IP-based communication over long distances. The evaluation shows that classic low-bandwidth applications are thus functional and can enable reliable, crisis-capable data transmission.},

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.},

abstract = {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.},

abstract = {In this paper, we present an approach to facilitate long-range device-to-device communication via smartphones in crisis scenarios. Through a custom firmware for low-cost LoRa capable micro-controller boards, called rf95modem, common devices for end users can be enabled to use LoRa through a Bluetooth, Wi-Fi, or serial connection. We present two applications utilizing the flexibility provided by the proposed firmware. First, we introduce a novel device-to-device LoRa chat application that works a) on the two major mobile platforms Android and iOS and b) on traditional computers like notebooks using a console-based interface. Second, we demonstrate how other infrastructure-less technology can benefit from our approach by integrating it into the DTN7 delay-tolerant networking software. The firmware, the device-to-device chat application, the integration into DTN7, as well as the experimental evaluation code fragments are available under permissive open-source licenses.},

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},

Not only in the private user space, but also in business operations and societal areas, they are deeply involved: Ranging from messaging services or navigation over (critical) SCADA systems to whole digital cities and communities. Consequently, the view on communication networks in security and particularly crisis scenarios becomes inevitable. This paper examines the notions of resilience, adaption and transition within communication networks with a specific focus on crises. Based on a structured literature review, the fundamentals of resilience and communication networks are introduced. The paper then discusses the characteristics of (a) evolvability, accessibility, usability and diversity as well as (b) self-organization, -management, -optimization, - monitoring, -healing and -protection for communication network resilience. Finally, it outlines challenges and potentials of communication network resilience based in the use cases of security and crises.},
