Following the success of our exhibitions Secret Communications 1 and Secret Communications 2, Crypto Museum has once again teamed up with the Foundation for German Communication in Duivendrecht (near Amsterdam, Netherlands) for the exhibition Secret Communications 3. This exclusive exhibiton will be open to the general public the following days:

  • Saturday 16 November 2019
  • Saturday 23 November 2019
  • Saturday 7 December 2019
  • Saturday 21 December 2019
  • Sunday 12 January 2020

On these days, we will be open from 10:00 to 17:00 and admission is free. Furthermore, coffee, tea and sandwiches will be available free of charge. We will be showing an exciting collection of cipher machines and espionage gear, some of which have never been on public display before. Check the overview below to see what we have selected for you. Large groups may apply for a visit outside the regular opening days and times. Contact Arthur Bauer to make arrangements.


The exhibition will cover the following four main themes:
  • 1. Enigma & Friends
    Enigma is arguably the most famous and well-known cipher machine in the world. We have shown it previously in its many variations, with all kinds of peripherals, as it was used by the German Third Reich during World War II for their secret communication. We will show it again this time, complemented by other technologies, such as secret telephone scramblers from World War II. In addition, Tatjana van Vark will show and demonstrate her wonderful Super-Enigma, but note that she will not be present on all opening days.
  • 2. Bugs
    This time we will show some unique covert listening devices (bugs) that were used during the Cold War by the Stasi and the CIA. We will also explain the methods of hiding such devices and how sweep-teams were able to track them down. We are able to give a good impression of the techniques used by the West as well as by the Eastern Block, and will be able to show some exiting examples. Note that many of the bugs used by the CIA were developed and manufactured by a Dutch company, from the 1950s well into the 1990s.
  • 3. Philips Crypto
    As Crypto Museum is based in Eindhoven, some of our collection is dedicated to the history of cipher machines that were developed by Philips Usfa (later: Philips Crypto). Over the past few years, our collection has grown to the extent that we are now able to show most of the equipment that was developed and manufactured by this company. See why Philips Crypto once belonged to the — big four — in the crypto-world and why Philips was allowed to supply to NATO. An impressive range of impressive products. Hear the story of the rise and fall of Philips Crypto.
  • 4. Car phones (ATF)
    In addition to the above subjects, we will share with you the history of car phones (cellular networks) in the Netherlands in the days before GSM. Learn how the networks were penetrated by criminals, to use it for blackmailing and for making clandestine phone calls. We will be showing items that have been confiscated by the police and that have not been on public display before. Learn how cryptography and authentication became mandatory in the GSM network, and what role PTT Telecom (now: KPN) played in this.

    We will also show tapping techniques for both mobile and land lines, including a complete tapping room of the police who – in cooperation with PTT Telecom – intercepted criminal conversations. One small restriction: on the days that Tatjana van Vark demonstrates her Super-Enigma, some of this material will not be on display.
