Directive (EU) 2023/2661 formally recognises the EU C-ITS security credential management system (EU CCMS) to support large-scale commercial C-ITS deployment in Europe. The Commission is ensuring that the European Root CA fulfils its role. This tender is meant to ensure the continuity of the provision of the EU Root CA. The authority needs to be maintained to be used by all entities participating in the testing environment of the European C-ITS trust model and to support migration plans in the event that another root certification authority is compromised.
