Security Issues of Blockchain-Based Information System to Manage Supply Chain in a Global Crisis

Abstract

Global supply chain crisis management has become increasingly crucial for tackling unusual incidents (e.g., natural disaster, terrorism, pandemic). While crisis management has focused on a few organizations involved in supply chain operations (manufacturers, governments, carriers, and the consuming public), it has primarily received a functional focus. Due to their decentralized network structure, supply chains are prone to suffer from disruptive events solved by supply chain crisis management. This chapter presents the blockchain technologies' possibilities and limits used in an integrated IoT-based information system architecture. The chapter describes how the scalability limits of blockchain technology affect the proposed architecture performance that uses it. Also, the chapter presents a review of the academic literature, pointing out how some solutions use a centralization process to improve response time and security of the blockchain-based architecture. Finally, the chapter provides security threat models, which consider by blockchain protocols in IoT networks.
