Electronic time stamp
An important tool to ensure the existence and integrity of the document
Electronic time stamp issued by TSA CA Disig is compliant with the requirements of the Act No. 215/2002 Coll. on electronic signature, as amended, as well as with requirements prescribed by RFC 3161 Internet X.506 Public Key Infrastructure – Time-Stamp Protocol (TSP).
Our accredited certification service for issuing time stamps uses the accurate time learned by use of NTP server connected to the accurate time source provided by the GPS satellites. Private keys are stored on a HSM (hardware security module), which complies with FIPS 140-2 level 3 requirements and is certified by the Slovak NSA.
A time stamp can be provided upon request for a time stamp addressed to the TSA CA Disig (the time stamp issuer) via a webpage application (HTTP or HTTPS protocols) of the server TSA CA Disig or via standard port of the time-stamping service (318), which is installed on the client´s side (in the client´s software). A request contains a digital fingerprint of the document to which the time stamp should be attached, generated based on the approved hash function.
A customer can request a time stamp by using an authorization token (a certificate used to log in to the time-stamping server) installed on a specific PC (or more PCs). Access to the service can be also enabled from a specific IP address, depending on the particular agreement.
