20.500.12556/DKUM-86474 Towards a Catalogue of Self-Sovereign Identity Design Patterns Self-sovereign identity (SSI) is a user-centric, decentralised identity approach that provides a means for identification, authentication, and authorisation without the involvement of external entities, responsible for identity provisioning and management in current centralised and federated approaches. In general, the basic building blocks of an SSI system include decentralised identifiers, verifiable credentials, identity wallets, a verifiable data registry, and three main actors: issuer, identity holder, and verifier. Even though the SSI field is dominated by proposals, SSI systems can be implemented in different ways, which is reflected in the absence of a well-defined architecture. Thus, the best implementation is still a matter of research, the requirements of the individual system, and its field of application. However, well-designed and implemented systems are crucial to avoiding failures, speeding up the development process, ensuring high quality, and the broader adoption of SSI solutions. Hence, the main objective of this study was to identify design patterns and good practices of the SSI ecosystems by reviewing and analysing the literature, technical documentation, and existing SSI implementations. Therefore, the study is built on existing knowledge, and presents a comprehensive catalogue of thirty-five SSI design patterns that can serve as a starting point for a possible SSI system design. self-sovereign identity decentralised identity design patterns decentralised identifiers verifiable credentials blockchain verifiable data registry identity wallets identiteta verižni bloki identikacijske denarnice true true true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/ © 2023 by the authors Članek v reviji 2023-12-04 20:50:57 2023-12-05 08:01:38 2024-05-21 07:12:18 0000-00-00 00:00:00 2023 0 0 23 9 13 2023 0000-00-00 Zaloznikova Objavljeno apc 2023-03-07 2023-04-23 2023-04-26 004.7 2076-3417 151388419 10.3390/app13095395 2076-3417 applsci-13-05395.pdf applsci-13-05395.pdf 1 889CD6AF630232818CD0F82BBF56FB19 139c07e059899e3127cdc6e618365a835926002a031908d7f41e2084ed541fcd 9c5fffe2-92de-11ee-9395-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174584 https://www.mdpi.com/2076-3417/13/9/5395/pdf 1 bca5de31-92de-11ee-9395-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174585 Fakulteta za elektrotehniko, računalništvo in informatiko Univerza v Mariboru 0 0 0
