Method and device for the generation of checkable forgery-proof documents

摘要

A method for the generation of forgery-proof documents or data records, whereby key information is generated and whereby encrypted checking information is formed from the key information and from a transaction indicator comprises generating random key information and the forming the encrypted checking information from the key information and from a transaction indicator in a cryptographically reliable contact station, encrypting the key information in the cryptographically reliable contact station, transmitting the encrypted checking information and the encrypted key information by the cryptographically reliable contact station to an intermediate station, the intermediate station temporarily storing the encrypted key information and the encrypted checking information and subsequently transmitting this to a cryptographic module of a document producer at a different point in time from the transfer between the cryptographically reliable contact station and the intermediate station
