Solutions, by what you do with signatures.
Perennis adds the quantum-safe signature to documents and checks that it is still there. Where it fits depends on whether you issue signatures, check them, or rely on them in public administration.
Signing
Trust service providers and signing platforms
Add a quantum-safe signature (ML-DSA-65) to the PAdES signatures you issue, together with the certificate authority and time-stamps it needs.
For providers → ValidationValidation services
Check the quantum-safe signature alongside EU DSS and give one result for both signatures.
For validation services → Public sectorAdministrations and European Digital Identity Wallet teams
Start with a limited pilot in a controlled environment, together with a trust service provider.
For the public sector →What we can do today, and what not yet.
What Perennis is today
- A working system that signs PAdES documents with ECDSA P-256 and ML-DSA-65 together, and checks both signatures.
- It uses the pair that ETSI TS 119 312 V2.1.1 names for PAdES (Table 3.3).
- The method is peer-reviewed and published: Cryptography 2026, 10(5), 70.
- It works alongside the validators you already use, not instead of them.
What is still missing
- Qualification as a trust service. The signatures are advanced (AdES), not qualified (QES).
- A conformity assessment. No conformity assessment body has assessed it yet.
- Certified hardware for the keys. They are in a software module, not in a certified QSCD or HSM.
