Notice Regarding the Transition of European Trusted Lists from TLv5 to TLv6

Based on the amendment to the eIDAS Regulation (Regulation (EU) No. 910/2014), specificallythe newRegulation (EU) 2024/1183, a mandatory transition from theTLv5trusted list format to the newTLv6format is taking place throughout the European Union. Trusted Lists (TL) are official lists containing information on trusted trust service providers and their qualified services in accordance with the eIDAS Regulation. This change requires the rapid implementation of new technical standards associated with the transition to TLv6.

The need to implement new standards affects all organizations that verify electronic signatures, seals, and time stamps as part of their processes for handling electronic trusted documents. It therefore also has a direct impact on certain features of the ELDAx platform.

Expected date for the transition from TLv5 to TLv6

The final version of the amendment will be submitted to the European Commission for approval in the coming weeks, and it is expected to take effect sometime in June or July 2025. The European Commission notes that there will be no transition period.

Technical Information

TheELDAxplatformusesTrusted Lists for the following functions:

  1. Validation of qualified electronic seals, signatures, and time stamps (/Validation module): a module and its functionalities used for external systems, such as eSSL.
  2. Internal requirements within the Long-Term Archiving (LTA) process (/BASE module).

To ensure a smooth transition to TLv6, it is necessary to upgrade the part of the ELDAx platform responsible for processing Trust Lists. Since different versions of the ELDAx platform are in use in the customer’s environment, the upgrade procedure varies.

  • For versions 7.XXX and later, this is a zero-downtime update; the change does not affect the integration interface or any other platform features
  • For versions 7.XXX and earlier, this is a standard upgrade to the latest version of the ELDAx platform, which supportsTLv6

Given the significant impact on certain features of the ELDAx platform, we recommend upgrading as soon as possible. The latest version of ELDAx supports both TLv5 and TLv6 and is designed to ensure a completely seamless transition.
