SimpulseID Credentials

SimpulseID is the credential and identity framework for the ENVITED-X Data Space, operated by the Automotive Solution Center for Simulation e.V. (ASCS e.V.). It is deployed at identity.ascs.digital.

SimpulseID enables verifiable onboarding of organizations and users, program membership verification, and secure authentication across ENVITED-X services using W3C Verifiable Credentials v2 and did:ethr identifiers.

Architecture

SimpulseID is built as a domain layer on top of harbour-credentials (by Haven). Harbour provides the ecosystem-agnostic cryptographic infrastructure (signing, verification, SD-JWT, delegation), while SimpulseID adds ENVITED-specific credential types, membership chains, and Gaia-X Trust Framework alignment.

+------------------------------------------------------+
|  SimpulseID (this repo)                              |
|  - 5 credential types + subject schemas              |
|  - Membership chains, program metadata               |
|  - ENVITED-X governance (ASCS e.V.)                  |
+------------------------------------------------------+
|  Harbour Credentials (submodule)                     |
|  - W3C VC v2 base types (HarbourCredential, CRSet)   |
|  - Gaia-X LegalPerson / NaturalPerson composition    |
|  - JOSE signing, SD-JWT-VC, delegation evidence      |
|  - did:ethr key management                           |
+------------------------------------------------------+

Each SimpulseID credential subject carries a mandatory harbourCredential IRI linking to a Harbour Gaia-X compliance credential, which serves as the baseline of trust.
