Abstract
An OT or Oblivious Transfer protocol is used to output pseudonym tokens from a list of pseudonym tokens to user entities such that it is possible to obtain pseudonymized authentication by a preceding verification of proof of identity of the respective user entities and marking pseudonym tokens as used as soon as the same are used for authentication by means of the OT protocol after the output.
