PKI infrastructure and certificates

The computer center is responsible for applying for and issuing server and user certificates. The corresponding certificates are registered and issued signed by the certification authority of Clausthal University of Technology (DFN-PKI service).

A user certificate enables you, for example, to digitally sign documents and encrypt e-mails. A server certificate also enables authenticated and tamper-free data transmission when using network services (e.g. via https).

Applications for user certificates must be submitted in person to an employee of the Participant Service (accredited persons). In addition, the attributes specified in the certificate must be verified by means of photo identification.

In the case of server certificates, however, it must be checked whether the certificate is for an official service on a computer at Clausthal University of Technology. This requires an accredited person from the respective TU Clausthal institution. The accreditation application must be completed in full and submitted in person (together with any initial certificate applications) to the Participant Service.
