Announcement: Secret Messages 3

By now, many of you will be aware of the fact that we - a cooperation of the Foundation for German Technology (CDV&T) and Crypto Museum - organise an exhibition every three years. By the end of 2019 we will launch yet another one, for which the preparations already have started.

The exhibition will cover 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 use 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 would like to share with you the history of car phones (cellular network) in the Netherlands in the days before GSM. Learn how the networks were penetrated by criminals who used 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 publick display before. Learn why cryptography and authentication became mandatory in the GSM network, and what role PTT Telecom played in this. In addition, 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.

Our house rules:
We kindly ask our visitors to register themselves at their arrival. Photographing is allowed, so please be aware of the fact that you may be caught on camera. There will also be CCTV cameras in operation. The footage from these cameras will be destroyed after the event.
