Self-Sovereign Identity (SSI) is a new digital identity paradigm that allows users to create and control their own identity, without relying on any centralised authority. A user can generate its own identity (Decentralized Identifiers) stored in a Distributed Ledger (DL) and associates authentic and demonstrable attributes to it (Verifiable Credentials). The Transport Layer Security (TLS) protocol version 1.3 is a client/server Internet protocol that allows two endpoints to communicate securely by providing authentication of the parties, confidentiality and integrity of the messages. In TLS identities are issued in the form of X.509 certificates by Certification Authorities (CAs), which are centralized entities who have full control on the certificates they emit.
