“…This could be achieved using various data anonymization and encryption techniques as well as careful selection and control of the shared extent of information. Privacy-preserving architecture for information exchange and use of homomorphic encryption in value chains was proposed by Chokparova and Urbas [73]. This research was based on investigations of previous implementations of additive homomorphic encryption techniques in different industries and the formulation of a confidentiality model applicable in MSCs.…”

The miniaturization and modularization of production capacity brings with it not only greater agility and efficiency, but also increased flexibility in the form of mobility. This flexibility allows production capacity to be moved when and where it is most needed, generating new business opportunities, e.g., allowing modular units to be rented, leased, or shared. This flexibility, however, requires information and control systems that ensure a correct and secure flow of information between different stakeholders of the supply chain. Based on this, the present article characterizes the concept of software-defined mobile supply chains, presenting its main requirements, opportunities, and limitations. In addition, we present two case studies in which the proposed concept is evaluated in order to demonstrate its applicability. Here, due to the new optimization problems that arise when considering mobile facilities, special interest is given to the planning and control of the required operations, as well as the difficulties associated with the exchange of physical and intellectual assets between different stakeholders.

“…It can be assumed that such a system requires a certain extent of trust between asset providers and operators. In addition, such collaboration and operation of assets in a value creating chain would require confidentiality protection of the exchanged and shared information [78]. Due to recent advances in information technology, the necessary data can be shared quickly and efficiently and provide information visibility in the collaborative environment [61].…”

This research investigates the tension between trust and confidentiality in Mobile Supply Chains (MSCs), where a production asset that is owned by one of the partners is outsourced to another partner of the supply chain for the production of goods, chemicals, or pharmaceuticals. The novelty of the MSC concept is to be found in its innovative and sustainable approach to production and operation processes in supply chains. Implementation of the MSC model could, however, raise trust and confidentiality concerns. The interplay of trust and confidentiality, or preservation of information privacy, between partners plays a central role in the supply chains, particularly because they are genuinely dependent on each other. Qualitative data analysis was used, in which semi-structured interviews with the experts from the chemical and pharmaceutical industries in Germany were conducted to investigate the tension between trust and confidentiality, and important factors affecting it. The results of the study present four different integration scenarios, namely, the low-quality, conservative, grey-box, and innovation scenarios, which consider different levels of trust, confidentiality and information sharing. Subsequently, the tension between trust and confidentiality is analyzed within these scenarios, and three effective strategies which encourage partners to balance the tension between trust and confidentiality are proposed. The study indicates that the balance between trust and confidentiality can be maintained in some scenarios when critical factors such as transparency, trust negotiation, and a reward-sharing system are present.

In the era of IoT and big data, an enormous amount of data being generated by various sensors and handheld devices and for sectors not limited to healthcare, commerce, smart driving, smart grids, and fintech requires privacy and security. Although security can be ensured once the data is in transit or at rest, for certain application domains need to ensure privacy computations over encrypted data. Homomorphic encryption (HE) is one mechanism that allows parties to compute any arbitrary functions in an encrypted domain. Homomorphic encryption schemes have been employed in various applied sectors for privacy preservation; however, the limiting factor of these schemes is the computational and communication overhead and associated security. This chapter reviews the types of HE schemes, the application domains, and the associated costs for privacy preserving computing and discusses the underlying mathematical hardness problems, security in the classical and post quantum era, and challenges and recommendations for tradeoff in applied domains.
