Who can help us to identify this spy radio set. It is believed to be from 1962 and was captured in China more than 30 years ago. cryptomuseum.com/spy/pd5/index.…

Last week, researchers of the Dutch security firm Midnight Blue disclosed that they had found vulnerabilities in the TETRA encryption algorithms. Crypto Museum now publishes the source code of the algorithms, along with a paper by the researchers: cryptomuseum.com/radio/tetra/bu…

Meet the ultimate rotor-based cipher machine, developed between 1952 and 1963 by Boris Hagelin: cryptomuseum.com/crypto/hagelin…

Don't forget: tomorrow is the first opening day of our exhibition Secret Messages 4: cryptomuseum.com/events/2023/sc… We have arranged for free parking! And the HX-63 -- the ultimate rotor machine -- is also on display.

Check out this passive covert listening device that was developed around 1963 and was used by MI6 to spy on German industrials: cryptomuseum.com/covert/bugs/ne… If anyone has further information about these devices, please let us know.

30 years ago, CIA and FBI used this type of equipment for wireless overhearing and recording of conversations and evidence gathering. Now fully functional again. cryptomuseum.com/df/aid/unitel2…

Lots of work done this week on #VirtualM209, the casing is now almost completed. The ghosted part is a CT scan of a real machine by DMD München (thanks Matthias Göggerle). Don't know about you, but I'm really excited about this one, it's looking awesome! TNMOC Bletchley Park CryptoMuseum

Last Friday, Crypto Museum received a most generous gift in the form of a KL-7 cipher machine, complete with all 12 rotors. It was donated by OVCISKLu -- the Society of Former Signals and CIS Officers of the Royal Dutch Air Force. MANY Thanks! cryptomuseum.com/news/index.htm…

Former #Wirecard-CEO Jan Marsalek and a former officer of the Austrian security service gave the Russian #FSB a laptop with the German encryption system SINA: archive.is/ClNSz

We are thrilled that #TNMOC has been honoured with full Accreditation as a Nationally Styled #Museum 🥳 This landmark achievement recognises our collections’ importance, our #Learning programme, and our #Research 📖 Thank you to all who supported us! ➡️ ow.ly/1vnE50RTMY5

Introducing Enigma D: manufactured in 1926, this the father of all later Enigma cipher machines, including commercial Enigma K and military Enigma I cryptomuseum.com/crypto/enigma/…

New discovery: the 'Condenser PBJ' rotor-based cipher machine was developed between 1922 and 1924 and was used until 1934 by the Czechoslovak Army. Full reconstruction now online in Cryptologia (free access) tandfonline.com/doi/full/10.10…

Full description of the recently rediscovered 'Condenser PBJ' rotor-based cipher machine (1922-1924), now on the Crypto Museum website: cryptomuseum.com/crypto/pbj/

Check out this power supply unit of 1965. It was used with the Fialka cipher machine (M-125) and proves that the Russians were well aware of TEMPEST and side-channel attacks. cryptomuseum.com/crypto/fialka/…

I've been learning about the SG-41, a mechanical pin-wheel cipher machine, developed as a replacement candidate for Enigma. This is complex, but I'm up for the challenge so ... introducing Virtual SG-41. Follow along as I try to work it out! Bletchley Park TNMOC CryptoMuseum

This device was used by the German Army to capture and decode Yugoslav telegraphy signals in Kosovo: cryptomuseum.com/telex/rs/ga082…

I broke more than fixed this week! I'd placed a few items in the machine out of line so last few bits didn't fit in. Had to check scan and correct placing. All fixed now! The question to answer today - "What happens if you run out of paper?" Bletchley Park TNMOC CryptoMuseum

This receiver from Watkins-Johnson played an important role in the Watergate Scandal (1972-1974) that eventually led to the resignation of US President Nixon in 1974. cryptomuseum.com/df/wj/rs111/

As well as working on modelling & animating the complex paper feed mechanism, I've been having a play adding a few extra visuals. Some useful (hiding specific parts of the mechanism to see how it works) and some just eye candy! TNMOC Bletchley Park Three.js CryptoMuseum

This wristwatch was used from 1974 onward by the German Federal Intelligence Service (BND). It contains a covert transmitter that can be used by an intelligence officer to signal a distress situation. cryptomuseum.com/covert/bugs/te…
