Issues related to ensuring the security of the functioning of the full logistic supply chain of dried fruit (SCDF) in Ukraine are considered. It is shown that the creation and function of the SCDF, compared to other supply chain management (SCM) class systems, raises a number of specific problems caused by the complexity of the interaction of raw material suppliers (fresh fruit), manufacturers of final products (drying, packaging), storage terminals, distributors, 3PL and 4PL providers (retailers). These problems are due to the fact that the interaction of participants in business processes in the SCDF generates a lot of material, financial and information flows, as well as flows of services from sources of raw materials to the final consumer. An important aspect of improving the performance of the SCDF is the development of methods and tools, and on their basis the applied information technology to ensure the reliability and security of the SCDF. To solve this problem, it was proposed to use the Blockchain technology to protect the telecommunication channels connecting the circuit elements from unauthorized access. The method of identification and authentication of digital objects of the SCDF, which guarantee the security of SCDF elements and provide them with the necessary level of confidentiality, is described.
