PKI - Identity Trustee

This service fulfills two tasks:

  1. A user can register with this service, so that the service issues a person pseudonym for him. The registration is offline, because the service must be convinced of the correctness of the user's identity data outside the identity management system. After registration of the user's data, the user gets a person pseudonym. This pseudonym is used in subsequent communication between user and this service.
  2. For registered users, the service can issue certificates for pseudonyms of the user, which state, that the service knows the users identity. Service providers may require such a certificate, in order to make shure, that a user can be deanonymized in case of misbehaviour.


  • Creating personal pseudonyms (offline)
  • Certifying pseudonyms (online)
