3D cipher

As part of the eHeritage funding, approximately 60 cipher machines from the cryptography collection of the Deutsches Museum are being scanned using CT scans at the Fraunhofer EZRT and made available to the public as open data. This form of digitization allows the study of the encryption technologies hidden within the devices without causing irreparable damage to the historical exhibits.

Tasks of the EZRT and involved project partners

Project goals are:

  • Methodically, the cipher machines of the collection will be CT-scanned.
  • Beyond this data provision, two main devices of the collection will be exemplarily detailed to provide a basis for presentations, visualizations, and model animations of the CT scans.
  • All data obtained from the project will ultimately be made available to research and the public as open data via the Deutsches Museum Digital portal.
  • Interim steps and results of this project will be published in lectures and publications during the project duration.

Cipher machine SG-41

The SG-41 cipher device is considered the successor to the Army Enigma deciphering machines. The digitization aims to assist researchers in the complete reconstruction of the encryption algorithm without having to physically open the valuable device.
