The public administration PKI (Public Key Infrastructure) provides a certificate-based infrastructure for electronic signing and encryption in order to protect confidentiality, integrity and authenticity in digital communications.

The following federal- and state-level public authorities have now signed up to using this infrastructure: these authorities are either themselves responsible for operating a Certificate Authority or have the PKI services rendered by commercial CA (Certificate Authority) service providers:

Other public authorities are currently at the project planning stage, so that their intended participation in the V-PKI will be achievable in the near future.
