About SK’s qualified 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.
