Security, secrecy, encryption; three very common words these days as both businesses and individuals attempt to keep messages and data secure. However, this is not a new concept, or one born out of the modern computer age – they’ve been buzz words for many, for hundreds, if not thousands of years.
Back in the 1930s a device was built to enabled banks to transmit secure messages about clients and transactions that could not be intercepted and read by others. That device was the Enigma machine, a device popularised by the film ‘The Imitation Game’ which dramatises the work of British code-breakers (headed by the likes of Alan Turing, Bill Tutte, Dilly Knox and Gordon Welchman) who worked tirelessly to break the encryption used by the Germans on their much enhanced Enigma machines.
At our meeting yesterday, following a short presentation, members of the Quantum Technology Club made their very own, fully working, Enigma machines that cost less than £5 each to build. They’re very simple to make and required those taking part to purchase a full sized tin of Pringles – flavour of their choice. The contents were to be eaten before the meeting, a chore for many 😭, and then brought along on the club night.
Supplied with some paper rings, an input and reflector to wrap around the tin the Enigma machine was complete in a relatively short period of time. Participants were then given a short phrase to encrypt and we’re please to say that all accomplished it.
World War II Enigma machines are far from commonplace and very expensive. However, the members of the Quantum Technology Club have added some more to the numbers available worldwide and we look forward to them appreciating in value alongside their wooden and metal counterparts from days gone by.
If you’re interested in taking part in more one-night projects like this, then do watch our calendar and come along – you’ll be made most welcome and there’s no need to be a member.
