“…Regularly rotating the keys is recommended to mitigate risks in case of a key compromise. The key rotation challenge has been addressed in [144]. One of the challenges is to ensure that only the DID creator, i.e., the person who knows the secret seed, can rotate to the next key pair.…”

Creating and utilizing digital identities are fundamental steps towards accessing online services. In order to facilitate the management of user identities, the concept of identity management has been introduced. Various systems and protocols have been developed to manage online identities. However, these systems are provider-centric, focusing on aiding providers in managing their user bases. As a result, users often have limited control over their identity data and remain unaware of how centralized identity providers use or potentially misuse their data. Self-Sovereign Identity (SSI) has emerged as a new paradigm in the digital identity management landscape, aiming to empower users by allowing them greater control over their identity data. Although SSI is a relatively new domain, there have been numerous efforts, primarily from the industry, to introduce SSI standards, protocols, and systems, with multiple options in each category. Researchers eager to contribute to the SSI domain might find it challenging to understand the interconnections among these components. Notably, the SSI domain faces several challenges, as highlighted in various research works. These challenges must be addressed before SSI can achieve widespread adoption. This article presents a comprehensive systematic literature review of SSI, offers a detailed taxonomy, and identifies and analyzes the open challenges in SSI.INDEX TERMS self-sovereign identity, digital identity, taxonomy

“…A research trend in SSI is to create and improve decentralized identifiers from the machine to the human level. Four research articles [ 148 , 149 , 150 , 151 ], two protocols [ 146 , 147 ], and one W3C standard [ 59 ] have been written in response to various challenges associated with decentralized identifiers .…”

“…This technique explores the pre-image resistance of cryptographic hash functions by constructing a chain of hash operations on a secret seed and revealing hash values in reverse order. Public-key cryptography is added to this scheme so that only the DID creator, i.e., the person who knows the secret seed, can rotate to the next key pair [ 150 ].…”

Self-Sovereign Identity (SSI) is an identity model centered on the user. The user maintains and controls their data in this model. When a service provider requests data from the user, the user sends it directly to the service provider, bypassing third-party intermediaries. Thus, SSI reduces identity providers’ involvement in the identification, authentication, and authorization, thereby increasing user privacy. Additionally, users can share portions of their personal information with service providers, significantly improving user privacy. This identity model has drawn the attention of researchers and organizations worldwide, resulting in an increase in both scientific and non-scientific literature on the subject. This study conducts a comprehensive and rigorous systematic review of the literature and a systematic mapping of theoretical and practical advances in SSI. We identified and analyzed evidence from reviewed materials to address four research questions, resulting in a novel SSI taxonomy used to categorize and review publications. Additionally, open challenges are discussed along with recommendations for future work.
