Trusted third party

A trusted third party is a neutral and independent actor whose mission is to secure an exchange between two parties: in electronic signatures, it attests to the identity of signatories, seals the document, time-stamps actions and preserves evidence. Historically, notaries played this role for paper deeds. In digital, the trusted third party is formalised by the eIDAS regulation in the form of trust service providers (TSP) and their qualified version (QTSP). Certyneo acts as a trusted third party by issuing advanced signatures (AES) and can delegate to a partner QTSP to issue qualified signatures (QES).
