Time-Stamping Service

SK’s qualified Time-Stamping Service certifies the existence of specific data at a certain point of time. It is, therefore, widely used in digital signing or archiving documents.

Time-Stamping Service uses PKI and trusted time sources to provide secure and reliable information that is compatible with international standards (RFC 3161). Our PKI-based Time-Stamping Service is protected using
digital signature, meaning that no one is able to change the data once it is recorded and confirmed with SK's time stamp.

As a trust service provider included in the European Trust List, SK is the first to issue the eIDAS qualified time stamps. SK’s Time-Stamping Authority is recognized with a certificate for issuing qualified electronic time stamps that meet the eIDAS requirements.

SK issues millions of time stamps a month to our customers all over the world. We have high customer satisfaction and an advantage of a good price-to-quality ratio for our service. 

Benefits from SK’s qualified Time-Stamping Service include:

  • guarantee from SK as a trust service provider included in the European Trust List;
  • certified service that meets the eIDAS requirements for qualified electronic time stamps;
  • digital signatures in ASIC-E format accepted all over the EU;
  • non-repudiation of data and documents.
