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 signature, they attest to signatories'' identity, seal the document, time-stamp actions and preserve evidence. Historically, notaries played this role for paper documents. In the digital realm, the trusted third party is formalized by the eIDAS regulation as 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).
