    3. Website Authentication

Servers and websites available on the internet must be clearly attributed to their operators if users are to trust them. The secure identification of websites and server systems on the internet takes place using electronic certificates.  

As an accredited testing and certification body, TÜViT supports trust service providers, from the planning of their services to the necessary tests and certification.  


Our approach

As a testing and certification basis, we utilise national statutory requirements (e.g. the Trust Services Act, VDG), European legal standards (eIDAS), the Baseline Requirements and/or the Extended Validation (EV) guidelines of the CA/Browser Forum, or exclusively technical and organisational requirements (ETSI, WebTrust for CA).  

Our IT security experts apply an agile approach during the project, test and certification. You thus have the opportunity after each concluded phase, whether in the project or during the audits, to consult our experts. This allows the risk of unprofitable investments to be reduced.  

During the test for a qualified trust service, for example, the following standards would apply to the preparation of certificates for website authentication in accordance with eIDAS:

  • Legal standards: eIDAS or local legislation, e.g. the Trust Services Act
  • ETSI standards (ETSI EN 319 411-1, …411-2 and associated) or permitted alternative standards.

An eIDAS and ETSI certification can subsequently take place.

Electronic Archives and Archiving Services

Documents that are electronically signed or marked with a timestamp are subject to ageing, just like their hard copy counterparts. If the certificates or mathematical algorithms used there are no longer up to date, this results in them losing their value as evidence.
