xWiki for eIDAS: Trust Services Documentation

xWiki for eIDAS: Trust Services Documentation

The eIDAS Regulation establishes a legal framework for electronic identification and trust services across the European Union, enabling cross-border recognition of electronic signatures, seals, timestamps, and registered delivery services. For qualified trust service providers, the regulation imposes substantial documentation obligations covering security policies, certificate management, audit trails, and operational procedures. xWiki offers a structured documentation platform that helps trust service providers meet these requirements while keeping their documentation auditable, current, and accessible to supervisory bodies.

Understanding the eIDAS Documentation Landscape

eIDAS distinguishes between non-qualified and qualified trust service providers, with the latter subject to significantly more demanding requirements including regular conformity assessments by accredited bodies. Qualified trust service providers must maintain comprehensive documentation of their policies, practices, and procedures, and must make certain documents publicly available. The regulation references technical standards published by ETSI, particularly the EN 319 series, which specify the content and structure of trust service practice statements, certificate policies, and security documentation. xWiki's ability to create deeply structured, interlinked page hierarchies maps naturally onto these documentation standards.

Digital Signature and Certificate Policies

At the heart of any qualified trust service is its certificate policy and certification practice statement. These documents define the rules governing the issuance, management, revocation, and renewal of certificates. They are lengthy, highly structured documents that must be updated whenever practices change. In xWiki, a certificate policy can be maintained as a page tree where each section of the ETSI EN 319 411 framework has its own page, making it easy to update individual sections without navigating a monolithic document. Cross-references between the certificate policy and the certification practice statement are implemented as wiki links, ensuring consistency and making it simple for auditors to trace requirements to their implementation.

Certificate Management Procedures

Trust service providers must document every step of the certificate lifecycle, from initial identity verification through issuance, suspension, revocation, and expiry. xWiki can host detailed procedure pages for each lifecycle stage, including the identity proofing methods accepted, the validation checks performed, the technical process for generating key pairs, and the notification procedures triggered by revocation requests. Each procedure page can include process flow diagrams created with xWiki's diagramming tools, and attachments such as sample forms or verification checklists can be stored alongside the procedure they support.

Audit Trail Requirements

eIDAS and the supporting ETSI standards require trust service providers to maintain detailed audit trails of all security-relevant events. While the technical audit logs are generated by the trust service platform itself, the documentation describing what is logged, how logs are protected, how long they are retained, and who is authorised to review them must be maintained in the provider's documentation system. xWiki can host the logging policy, log review procedures, and records of periodic log reviews. The wiki's own audit trail on documentation changes complements the technical logs by providing evidence that operational procedures are actively maintained.

Cross-Border Recognition Documentation

One of eIDAS's primary objectives is enabling cross-border recognition of trust services within the EU. Qualified trust service providers must publish their status on the national trusted list maintained by their supervisory body. The documentation supporting this listing, including conformity assessment reports, supervisory audit responses, and notification records, can be organised in xWiki as a dedicated compliance space. When supervisory bodies request documentation during periodic audits, the trust service provider can grant read access to specific wiki spaces rather than exporting and transmitting document packages, streamlining the supervisory process considerably.

eIDAS 2.0 and the European Digital Identity Wallet

The revised eIDAS regulation introduces the European Digital Identity Wallet framework, which will require trust service providers to support new attestation types and interoperability standards. For providers preparing for eIDAS 2.0, xWiki offers a forward-looking documentation platform where new wallet-related procedures, technical integration specifications, and conformity evidence can be developed alongside existing trust service documentation. The ability to create parallel documentation spaces for current and future regulatory requirements ensures that the transition to eIDAS 2.0 is managed in an orderly, auditable manner.

Trust service providers operating across multiple regulatory frameworks will find value in our related guides on ISO 27001 documentation and AI Act compliance, both of which demonstrate xWiki's capacity for structured regulatory documentation.
