Root certificates

The T-Systems Trust Center operates several PKI with the root certificates “Deutsche Telekom Root CA 2”, T-Telesec Global Root Class 2“ and „T-Telesec Global Root Class 3“.

 

The root certificate is the topmost certificate in the directory tree of a certificate hierarchy and is self-signed. The publication makes it possible to check the validity of the certificates issued in these hierarchies. By installing the root certificates in applications (e.g., browser), all certificates issued can be checked for validity. The root authority only certifies certificates (CA certificates) directly from subordinate certification authorities.
 
Underneath this root authority, the T-Systems Trust Center operates various certification authorities for advanced certificates. In addition, the T-Systems Trust Center issues CA certificates for other operators of certification authorities.
