Signing and validation are end-to-end services
The document format and cryptographic operation are important, but they are not the complete system. Reliable outcomes also depend on signer or seal-creator identity, authority, consent, certificate status, trusted-list information, validation policy, evidence retention and business acceptance.
Areas of support
- Electronic signature and seal use-case analysis
- PAdES, XAdES, CAdES and ASiC format selection
- Signature creation, augmentation and validation architecture
- Validation policy, constraints and report design
- Trust anchors, trusted lists, revocation data and time evidence
- Long-term validation and preservation considerations
- European Commission DSS integration and configuration
- Security, dependency, test and operational review
Typical outputs
Service architecture
Actors, components, trust inputs, evidence flows, interfaces and failure handling.
Policy model
Signature classes, accepted formats, validation constraints and business outcomes.
DSS design
Integration decisions, configuration, data loading, reporting and operational controls.
Independent review
Focused assessment of design, implementation, test evidence or supplier material.
