Previously unknown instructions & settings sheets for the SG-41 have been discovered in Czech archives! Thanks to Eugen Antal, Carola Dahlke & Robert Jahn who published them in Cryptologia.
I've been working to bring these into Virtual SG-41

ABU covert distress transmitter Real watch with built-in distress transmitter, used by intelligence services for the protection of officers and VIPs.

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. www.cryptomuseum.com/covert/bugs/...

RS-111-1B receiver Watkin-Johnson RS-111 surveillance receiver, introduced in 1963 by CEI and produced until 1980. Played an important role in the Watergate Scandal.

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. www.cryptomuseum.com/df/wj/rs111/

Sometimes I can see how the mechanism works from the scans, but in complex cases, it can be best to just model it and see what happens. The rotor stepping of the SG-41 mechanism is in the second type! The answer is mind-blowing! @tnmoc.bsky.social @threejs.org @cryptomuseum.bsky.social

GA-082 Rohde & Schwarz GA-082 FSK analyzer, used from 1983 onwards for interception and analysis of telegraphy signals.

This device was used by the German Army to capture and decode Yugoslav telegraphy signals in Kosovo: www.cryptomuseum.com/telex/rs/ga0...

BPK-125 Fialka power supply unit with TEMPEST features

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. www.cryptomuseum.com/crypto/fialk...

Here’s the paper no one read before declaring the demise of modern cryptography The advance was incremental at best. So why did so many think it was a breakthrough?

A deeper look at recent claims by Chinese media of a “real and substantial” quantum computing “breakthrough” to attack SPNs, the underlying algorithms of modern cryptography including AES. Via @dangoodin.bsky.social.

TL;DR: Turns out, the death of modern cryptography is greatly exaggerated.

For the first time ever researchers crack RSA and AES data encryption Chinese scientists reveal D-Wave's quantum computers can break RSA encryption, signaling an urgent need for new cryptography solutions.
