Secure Electronic Signature

Act No. 272/2016 Coll. distinguishes between a simple electronic signature and a secure electronic signature. The secure signature must satisfy four conditions identical to Article 26 of eIDAS: unique linkage to the signatory, possibility of identification, the signatory's sole control over signing data, and detectability of changes. For communication with Slovak public authorities, a secure electronic signature with a qualified certificate (ZEPeK) is required — which is effectively a qualified signature (QES).
