List of trusted certification authorities to communicate with CS OTE

When requesting the inclusion of an authority in the list of trusted qualified authorities by CS OTE, it is necessary for the authority's certificate to have the required identification for a qualified electronic signature or seal issuance service, in accordance with the EU eIDAS Regulation No. 910/2014.

The URI for identifying this service is http://uri.etsi.org/TrstSvc/TrustedList/SvcInfoExt/ForeSignatures. Alternatively, for creating electronic seals, the URI is http://uri.etsi.org/TrstSvc/TrustedList/SvcInfoExt/ForeSeals.

You can find more information here

The list is updated and valid as of 08/2024.
