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: 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: Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management. This research focuses on the cross-border e-commerce context, to propose a blockchain-based framework, and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management. A general blockchain-based product traceability framework is introduced. This framework is based on a cross-border e-commerce supply chain context, incorporating a series of blockchain-based models, including multi-chain structure model, data management model and block structure model. Several core methods and algorithms are also developed, such as information anchoring method, key distribution method, information encryption algorithm and anti-counterfeiting method. The framework, models and methods form a complete and comprehensive solution, which are evaluated by applying to several typical problems and attack cases. The case analysis results show that the framework, models and methods can successfully deal with key recover problem, and protect against clone attack, counterfeit tag attack and counterfeit product attack. The effectiveness, extendibility, security, implementation and governance issues of applying these solutions are also discussed. This research contributes to the theoretical and practical literatures on blockchain technology, cross-border e-commerce and supply chain management research fields. Collapse

Abstract: Security of private information is a critical requirement for information sharin ... Expand

Abstract: Security of private information is a critical requirement for information sharing in supply chains. Security is measured on a variety of metrics: participating suppliers in a supply chain process need guarantees on confidentiality, anonymity, and privacy; the purchaser needs assurance on verifiability and non-repudiation. Given the mutually exclusive nature of security metrics such as anonymity vs. non-repudiation, and confidentiality vs. verifiability, the challenge is to design a process that satisfies all these metrics. In this paper, we propose three major processes that enable secure information sharing and secure computation of arbitrary supply chain functions. We evaluate and compare the secure processes using a ranking method and score function, which we propose for that purpose. We find that certain processes will be preferred over other processes, depending on the environmental characteristics and user preferences. Thus, our secure processes aim to solve major collaboration issues in supply chains. Collapse

Abstract: The pressure on enterprises to manage and improve their environmental sustainability is steadily increasing. Despite the growing awareness in the IS community and business practice, current IS solutions remain in an initial state. Sustainability benchmarking is seen as a novel and effective tool in this context. However, sustainability benchmarking faces two major obstacles: First, the heterogeneity of the data requires significant pre-processing, and, second, the sensitivity of the data causes enterprises to reluctantly share this data. Our contribution is twofold: After analyzing the data input problem and identifying appropriate and available solutions, we present a secure sustainability benchmarking service (SBS) to overcome the information-sharing problem. Our service uses homomorphic encryption to protect the data during processing and differential privacy to protect against leakages from the reports. Finally, we evaluate in detail a prototypical implementation of this secure sustainability benchmarking service and illustrate its applicability in industry. Collapse

Abstract: As the Internet’s phenomenal growth is increasingly discernible, electronic trading has become the trend in commerce and presents big challenges. Electronic trading represents an important electronic commerce application. Today there are numerous ways one can conduct business over the Internet through electronic trading centers where buyers and sellers can trade online. In this article, we analyze such applications and introduce a new electronic model that allows multiple buyers and sellers to conduct negotiations and trading. We present the system architecture, design, and implementation with a focus on the design of the client-server architecture under the object-oriented environment. Some unique features such as the negotiation mechanism, security and legal issues are also discussed. Collapse
