Approach for Cryptography Digital Ecosystem Deployment Inara OPMANE 1 and Rihards BALODIS Institute of Mathematics and Computer Science of University of Latvia, Latvia Abstract. The paper introduces the Cryptography Digital Ecosystem concept and describes the rationale for its implementation. A checklists approach is offered to ensure efficient and high-quality ecosystem deployment and helps to ensure consistency and completeness of necessary tasks. A collection of checklists are indicated, which have been analytically developed based on extensive analysis of public literature regarding the development of quantum encryption solutions and adequate compliance with the solution requirements. Keywords. Checklist, methodology, cryptography, digital ecosystem deployment, quantum cryptography, quantum key distribution (QKD) 1. Introduction An important research topic of the University of Latvia Centre for Quantum Computing Science is quantum computing: the theoretical aspects of quantum information including quantum algorithms, computational complexity, communications, and cryptography. As solutions of the practical application of quantum computing are in the nearest future, the strategy of the Institute of Mathematics and Computer Science of the University of Latvia (IMCS UL) is to use quantum technologies that can be applied now and immediately. The activity of IMCS UL was concentrated in quantum communications and encryption (quantum encryption) applications. IMCS UL started the development of quantum cryptography research topics in 2019 with the purchase and operational testing of Clavis 3 from ID Quantique (https://www.idquantique.com). In order to develop the research of quantum cryptography at the institute, close research cooperation has been established with industry: the State Joint Stock Company “Latvijas Valsts radio un televīzijas centrs” LVRTC (www.lvrtc.lv), mobile operator LMT (www.lmt.lv), telecommunication company TET (www.tet.lv), and the Electronic Communications Office of Latvia (www.vases.lv). Currently, QKD technology has been tested in LVRTC and LMT fibre infrastructure. The necessity of research is related to development of strategy for introducing a new comprehensive technology that could influence very different aspects and players of our everyday lives. The chosen research method is conceptual analysis. It includes data exploration gathered through literature research, in. The research strategy includes comparison and assessment of a different interpretation in theoretical research and its reflection on real situations analysed in the implementation of the European 1 Corresponding Author, Inara OPMANE; E-mail: inara.opmane@lumii.lv Proceedings of CECNet 2022 A.J.
