The aim of this study is to determine the current challenges related to security and trust issues in digital supply chains. The development of information and communication technologies (ICT) has improved the efficiency of supply chains, while creating new vulnerabilities and increasing the likelihood of security threats. Previous studies lack the physical security aspect, so the emphasis is on the security of cyber-physical systems. In order to achieve the goal of the study, traditional and digital supply chains, their security risks and main differences were examined. A security framework for cyber-physical risks in digital supply chains was developed.

This exploratory investigation aims to discuss current status and challenges, especially in aspect of security and trust problems, of digital supply chain management system with applying some advanced information technologies, such as Internet of Things, cloud computing and blockchain, for improving various system performance and properties, i.e. transparency, visibility, accountability, traceability and reliability. This paper introduces the general histories and definitions, in terms of information science, of the supply chain and relevant technologies which have been applied or are potential to be applied on supply chain with purpose of lowering cost, facilitating its security and convenience. It provides a comprehensive review of current relative research work and industrial cases from several famous companies. It also illustrates requirements or performance of digital supply chain system, security management and trust issues. Finally, this paper concludes several potential or existing security issues and challenges which supply chain management is facing.
