    LoRaWAN Security Issues and Mitigation Options by the Example of Agricultural IoT Scenarios
    Transactions on Emerging Telecommunications Technologies (ETT) .
    [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
    International Journal of Disaster Risk Science (IJDRS) . doi:10.1007/s13753-022-00404-7
    [BibTeX] [Abstract] [Download PDF]

    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.

    Transparency and Accountability in Privacy Oriented Data Disclosure Scenarios in Agriculture
    Behaviour & Information Technology (BIT) . doi:10.1080/0144929X.2022.2068070
    [BibTeX] [Abstract] [Download PDF]

    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.

    The Role of Privacy in Digitalization – Analysing the German Farmers‘ Perspective
    Proceedings on Privacy Enhancing Technologies (PoPETs) ;2021(3).
    [BibTeX] [Abstract] [Download PDF]

    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.

    Digital Privacy Perceptions of Asylum Seekers in Germany – An Empirical Study about Smartphone Usage during the Flight
    Proceedings of the ACM: Human Computer Interaction (PACM): Computer-Supported Cooperative Work and Social Computing ;5(CSCW2). doi:10.1145/3479526
    [BibTeX] [Abstract] [Download PDF]

    Since 2015, an increased number of asylum seekers is coming to Europe. These migration movements increas-ingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach theirtargeted destination countries. Asylum seekers often use smartphones for information and communicationpurposes. Even though there are many positive aspects in the use of such technologies, researchers have toconsider the perceived risks of this specific user group. This work aims at investigating the use of mobileinformation technologies by asylum seekers during their flight, especially taking privacy into account. Thus, itexamines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conductinga qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results showthat asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, suchas surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this,this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy andtrust leads to avoidance behavior, the insights of this study provide valuable information for the design ofassistance apps and collaboration platforms, which appropriately address the specific needs for digital privacyin the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.
