Public sector

The majority of all administrative processes, projects and regulations in the public sector must be supported digitally. MTG ensures the security and availability of the necessary data and IT infrastructures and supports the development and implementation of security concepts and guidelines.

Corporate PKI

Die MTG Corporate PKI issues, validates and deploys digital certificates for various use-cases in the public sector.

Social security institutions, parliaments and other public institutions can thus exchange and communicate data securely. Upon request, MTG will monitor and manage the operation of the PKI in the selected data centers.

Root CA

The main purpose of using certificates from a PKI is to create trust in the identities of the users of the network. A Root CA represents the highest level of trust by validating and certifying the Sub CAs (certification authorities). Root CAs play an extremely important role in the context of legal regulations and directives and must therefore be operated reliably and in a highly secured infrastructure. For the new identity card and also for smart metering communication in Germany, Root CAs from MTG are being used.


Der neue Personalausweis (nPA) der Bundesrepublik Deutschland ist mit einer Online-Ausweisfunktion für den Einsatz im Internet und an Automaten oder Terminals ausgestattet.

eID Server für neuen Personalausweis

The new identity card (eID) of the Federal Republic of Germany is equipped with an online ID function for use on the Internet and at machines or terminals. Companies that operate an online store or online services can take advantage of the eID in order to authenticate their customers. Thus, online business processes in the Internet can be made safer and easier than with the classic login through a username and password.

MTG offers an electronic identity server as a service to such companies. This creates a bridge between the ID card holder and an online store or online service provider (e.g. health insurance companies, energy suppliers, banks).
