Abstract: Strategic alliances require mutual trust and collaboration between organizations. To increase alliance perfor­ mance, organizations in a strategic alliance are more likely to interpret each other’s equivocal behaviors in a positive way to sustain the stability of the relationship. Different from traditional mechanisms to build inter­ organizational trust, blockchain facilitates trust among alliance partners via its technology advantages, for example, public ledger and distributed consensus. The decentralized and distributed nature of a blockchainbased system assures that no single organization can add information to the chain without an approval from the alliance, nor can it make unilateral changes in the system. Drawing from the Affordance Theory, we propose an exploratory research design to understand the structure of a blockchain-based system, as well as how this blockchain-based system influences interorganizational trust in a strategic alliance and how blockchain-enabled interorganizational trust influences alliance performance. The case studies of two eastern banks indicate that the technical features of blockchain can help reduce equivocal behaviors and improve interorganizational trust. We discuss the findings and conclude the paper with implications. Collapse

Abstract: The introduction of blockchain offers new opportunities to rethink enterprise identity management. Recently, a new concept has emerged in the blockchain community called self-sovereign identity. Self-sovereign identity combines several existing decentralized identity management approaches, promising new ways to promote more convenient, connected, and secure identity services for the private and public sector. Nevertheless, research in this area is still in its infancy. Most of the very few articles focus either on the opportunities self-sovereign identity might offer or on very specific technical features. Studies on real-world applications of organizations using modern self-sovereign identity implementations and design theory are very rare. To fill this gap, we follow the design science research approach to design, implement, and evaluate a self-sovereign identity system to present tax attributes of online retailers. We present four design principles and conclude that the use of self-sovereign identity and blockchain offers opportunities to improve verification processes. Collapse

CRYPTOCURRENCIES, STABLECOINS AND CENTRAL BANK DIGITAL CURRENCIES: THE IMPACT OF TRUST AND PERCEIVED RISK

Abstract: Financial technology is undergoing rapid developments with the arrival of cryptocurrencies, the introduction of stablecoins, and more recently the discussion surrounding central bank digital currencies. The adoption of these technologies has received significant attention, but there has not yet been any research as to how the adoption factors for the three currencies differ, given their inherent similarities. This paper proposes to estimate the effect of trust and perceived risk on the adoption intention of the three aforementioned payment systems by creating three closely-matched questionnaires for each digital currency. This will enable us to estimate the effects of risk and trust in a way that makes it possible to compare the effect sizes for the different technologies, and can help evaluate whether a reduction of perceived market risk is sufficient for cryptocurrency adoption, and whether backing by the central bank may confer more benefits to adoption than the trustlessness touted for cryptocurrencies.

Abstract: Given the growing pervasiveness of information systems (IS) in everyday life, recent research has acknowledged that IS technologies are often not value free but are instead infused with fundamental personal values. However, little is known about how such values explain why people assimilate these technologies and their affordances. In the intriguing case of Bitcoin, personal values-especially libertarian political values-played an essential role in clarifying the ideological underpinnings of Bitcoin and its early adoption. Consequently, we draw on research on personal values and affordance theory to develop and test a model explicating how these personal values guide individuals toward using IS applications with salient affordances that address their values. Specifically, we hypothesize and test how individuals' personal values (i.e., libertarian political values) influence their attitudes toward Bitcoin affordances and their Bitcoin use behavior using data from a multiple administration survey of 236 users and nonusers of Bitcoin. Our results indicate that libertarian political values affect individuals' attitudes toward Bitcoin affordances, which in turn mediate the effects of these values on actual Bitcoin use. Our findings advance the field by demonstrating the importance of integrating values into the conceptualization of IS technology affordances. Collapse

Abstract: Narrowband Internet of Things (NB-IoT) is a wireless communication technology that enables a wide range of applications, from smart cities to industrial automation. As a part of the 5G extension, NB-IoT promises to connect billions of devices with low-power and low-cost requirements. However, with the advent of quantum computers, the incoming NB-IoT era is already under threat by these devices, which might break the conventional cryptographic algorithms that can be adapted to secure NB-IoT devices on large scale. In this context, we investigate the feasibility of using post-quantum key exchange and signature algorithms for securing NB-IoT applications. We develop a realistic ns-3 environment to represent the characteristics of NB-IoT networks and analyze the usage of post-quantum algorithms to secure communication. Our findings suggest that using NIST-selected post-quantum key-exchange protocol Kyber does not introduce significant overhead, but post-quantum signature schemes can result in impractical latency times and lower throughputs.

Abstract: Public auditing and data deduplication are integral considerations in providing efficient and secure cloud storage services. Nevertheless, the traditional data deduplication models that support public auditing can endure the enormous waste of storage and computation resources induced through data redundancy and repeated audit work by multiple tenants on trusted third-party auditor (TPA). In this work, we introduce blockchain-based secure decentralized public auditing in a decentralized cloud storage with an efficient deduplication model. We employ blockchain to take on the task of centralized TPA, which also mitigates the implications of malicious blockchain miners by using the concept of a decentralized autonomous organization (DAO). Specifically, we employ the idea of redactability for blockchain to handle often neglected security issues that would adversely affect the integrity of stored auditing records on blockchain in decentralized auditing models. However, the proposed model also employs an efficient deduplication scheme to attain adequate storage savings while preserving the users from data loss due to duplicate faking attacks. Moreover, the detailed concrete security analysis demonstrates the computational infeasibility of the proposed model against proof-of-ownership, duplicate faking attack (DFA), collusion attack, storage free-riding attack, data privacy, and forgery attack with high efficiency. Finally, the comprehensive performance analysis shows the scalability and feasibility of the proposed model. Collapse

Abstract: Demand for food delivery services has grown significantly in recent years and, in particular, during the COVID-19 pandemic and the resulting stay-at-home orders. From a business perspective, food delivery platforms work as intermediaries by mediating interactions among customers, restaurants, and delivery workers. This paper suggests that blockchain technology coupled with smart contracts can help remove centralized food delivery platforms by enabling peer-to-peer interactions among stakeholders. Following the design science research framework, we first conducted interviews with some relevant stakeholders. We use the obtained responses to design requirements related to cost reduction, transparency, and privacy. We thereafter suggest three design principles to tackle the design requirements. Next, we design and instantiate our artifact based on a decentralized business process model and blockchain technology. Finally, we evaluate our solution in terms of its potential for cost reduction and handling conflicts. Collapse

Abstract: The use of Electric Vehicles (EVs) has been gaining traction in recent years due to various reasons. While charging their EVs, users expose their identity and personal details, and an adversary being able to identify and track where users charge their EVs is a potential privacy threat. In this article, we propose a user-empowered privacy-preserving authentication protocol for EV charging based on Decentralized Identifier (DID) and Verifiable Credential (VC) to provide Zero-Knowledge Proof (ZKP)-security. The proposed method gives users full control over their identities and allows them to remain anonymous while charging from any station. Giving control over their identities empowers users. At the same time, by making use of the concept of VC, other parties can verify that a user is legitimate and authenticate the user before providing charging services. Hence, the proposed protocol makes the charging service available in a secure way, while empowering users and preserving their privacy. Collapse

Abstract: The General Data Protection Regulation highlights the principle of data minimization, which means that only data required to successfully accomplish a given task should be processed. In this paper, we propose a Blockchain-based scheme that allows users to have control over the personal data revealed when accessing a service. The proposed solution does not rely on sophisticated cryptographic primitives, provides mechanisms for revoking the authorization to access a service and for guessing the identity of a user only in cases of need, and is compliant with the recent eIDAS Regulation. We prove that the proposed scheme is secure and reaches the expected goal, and we present an Ethereum-based implementation to show the effectiveness of the proposed solution. Collapse
