Institute for Advanced Simulation (IAS)
These pages contain web links for requesting and managing so-called X.509v3 certificates, which are used to verify the authenticity of keys, which are mainly used to secure communication with e-mail partners and servers. The certificates issued by the JSC are part of the DFN-PKI (Public Key Infrastructure). The certification authorities of this PKI are operated by DFN-Cert Services GmbH.
Information on certificates and their use at Forschungszentrum Jülich can be found in the technical brief information TKI-365 (in German)
Provisions for the correct use of certificates of DFN-PKI by the certificate holders are described in the document "Informationen für Zertifikatinhaber" (in German).

The signed certificate application must be handed out to the subscriber service (Teilnehmerservice) at JSC (Dispatch).
Attention: In the case of user certificates, a personal authentication of the applicant at JSC-Dispatch is required for the first application. JSC-Dispatch is obliged to check your identity card.
This authentication is not required for a subsequent application if the last authentication was less than 39 months ago. In this case, the signed application can also be sent by mail or as an attachment to an electronically signed email to dispatch.jsc@fz-juelich.de.
After generating the certificate, the applicant will be notified of the completion by email. This mail contains links that can be used to import the certificate (and the certificates of the certification bodies).
These emails are electronically signed. The sender and holder of the signature certificate is dfnpki-mailsender-noreply@dfn-cert.de

FZJ employees have two classes of user and server certificates in the DFN-PKI: Global certificates and Grid certificates.
Validity | user certificate | server certificate |
Global | 3 years | 825 days |
Grid | 1 year | 1 year |
Grid certificates are only used by users and servers in the specific context of grid computing. This second class of certificates is required in addition to the "normal" Global certificates, because certain applications in the Grid environment do not support a hierarchical trust structure.
