Zodiac Killer's message Z340 solved
27 March 2024

The case of the Zodiac Killer is one of the most widely known unsolved killer cases in history. In 1969, the killer communicated with the FBI in a series of ciphers, some of which remained unsolved to this day. After 51 years, David Oranchak, Sam Blake and Jarl Van Eycke have finally solved the 340-character cipher known as Z340, which appeared to be a combination of a transposition and a homophonic substitution cipher. Today, the authors have published their solution – which has meanwhile been confirmed by the FBI – in an extensive 61-page paper.

TETRA TEA1 algorithm broken
9 August 2023

On 24 July, researchers of the Dutch security firm Midnight Blue published details about five vulnerabilities they had found in the encryption algorithms of the TETRA radio network. TETRA is used in many countries for the communication of public safety and emergency services.

Today, Midnightblue is publishing the source code of the reverse-engineerd encryption algorithms, as part of their talk at the Black Hat 2023 conference. The sources are published simultaneously by Crypto Museum, along with a paper written by the researchers.

Bug in WikiLeaks CryptoPhone
22 march 2022

In March 2018 a sophisticated bug was found inside a CryptoPhone IP-19 that had been used in London for several years by whistleblower platform WikiLeaks, in relation to the revelations of NSA whistleblower Edward Snowden.

It demonstrates the security of the CryptoPhone, which apparently was very good, but also shows how far certain intelligence services are prepared to go to achieve their goals. In this article, we review and analyse this high-tech bug.

Dutch state secrets
17 February 2022

An interesting book for the Dutch-speaking community: Staatsgeheim, De Beveiliging van Overheidsberichten. This book describes the development of cipher machines in The Netherlands in the post-WWII era, between 1945 and 1970. These machines were developed the author's father, Professor R.M.M. (Roelof) Oberman, at the time one of the leading scientists at the Dr. Neher Laboratory of the Dutch state-owned telecom provider PTT.

The book is unique in that it is the first to describe the era after the rotor-based cipher machines and before software-based solutions. The era of the unbreakable One-Time Pad (OTP) and of cipher machines that were based on non-linear feedback shift registers (NLFSR). The book is based on R.M.M. Oberman's personal archive, complemented by documents found in the Dutch National Archives and in the archives of the Dutch General Intelligence Service AIVD, most of which were classified until now, and have never been seen by the public before.

SpellMaster algorithm
3 August 2022

A few weeks ago we received a small SpellMaster pocket computer from the mid-1980s as a gift from one of our readers. This device has a built-in encryption function of which the algorithm was unknown. On 26 July, we asked our readers to reconstruct the algorithm, based on a set of known PT/CT pairs, in combination with a code snippet that was published in the original patent.

Today, we are happy to announce that the first solutions were reported just three days later and that working code examples are now available in Phython, C and BBC BASIC.

HistoCrypt 2022
20-22 June 2022, Amsterdam (Netherlands)
The International Conference on Historical Cryptology 2022 will be held in Amsterdam (Nether­lands) towards the end of June. This three day event is open to anyone, and touches a plethora of subjects related to cryptology and its history. One of the key speakers on the first day will be Maarten Oberman, who has rewritten the post-WWII cryptographic history of The Netherlands.

On the second day, Crypto Museum's Paul Reuvers and Marc Simons will give a detailed account on Operation RUBICON — a covert operation of the American CIA and the German BND in which they secretly purchased a large crypto-manufacturer in neutral Switserland – Crypto AG (Hagelin) – and used it to read the diplomatic traffic of more than 130 countries until 2018.

On the third day, key speaker Gerhard Strasser will take us back several centuries to show how sign language and other forms of non-verbal communication were once used for passing secret messages. In addition there will be sessions on cipher machines, historical documents, machine learning, tools, resources and more.

Registration is open until 12 June 2022.

FBI releases file about the Great Seal Bug
16 March 2022

In 2015 we published the most complete tear down of the Great Seal Bug, a.k.a. The Thing — a covert listening device that was developed by the Russians and planted in the study of the US Ambassador in Moscow. It was used to eavesdrop on the Ambassador for more than 7 years.

At the time, we used partly declassified reports and correspondense of the FBI, and undisclosed files from the CIA, and combined it to make a best educated guess on how the bug might have worked. At the time, the full technical report of the FBI about the device was still classified.

Apparently, our efforts have payed off, as the FBI has finally decided to disclose their full technical report, including photographs and technical drawings of the device. We have updated our page about this passive bug accordingly.

The release of the report also puts and end to the discussion about the frequency on which the device worked, and whether or not the activation signal used the same frequency as the signal that was (re)transmitted by the device. It appears that we were right all along 😊.

NSA algorithm for the PX-1000Cr broken
16 February 2022

In 1983, a small Dutch company by the name of Text Lite introduced the PX-1000 — a small pocket computer with built-in modem that was able to send DES encrypted texts through an analog telephone line. The device was dubbed Pocket Telex, and was also sold by Philips.

In April 2019 we revealed that in 1984, the NSA persuaded Philips to buy the entire stock from Text Lite and replace DES by an alternative encryption algorithm that was supplied by the NSA. At the time we assumed, of course, that the NSA algorithm was weaker than DES, but we were never able to prove that. Until now.

Yesterday, computer scientist Stefan Marsiske published a lengthy article in which he shows how he can break any message created on the PX-1000Cr in less than 4 seconds on a laptop, with no more than 17 characters of ciphertext.

For his break, he used the description of the algorithm published by Crypto Museum in January 2016, in combination with a disassembly of the code he made with IDA Pro. After creating a functional replica of the algorithm in C, he was able to use a number of of-the-shelf software frameworks to solve the problem. This proves that the algorithm is (much) weaker than DES.

Rudi Staritz dies at 99
24 July 2021

We have just received the sad new that this afternoon Rudolf Staritz has died at the age of 99. Rudi was the last surviving eyewitness who worked on and with the German spy radio sets of World War II. In the 1970s and 80s he published a large number of articles on this subject.

With his bright mind and sparkling personality he was a tree of knowledge for many radio HAMs, collectors, researchers and museums, ourselves included. In November 2019 he was the Guest of Honour during our exhibition Secret Communications 3. He will be missed dearly.

Machines rediscovered at the NCM
2 July 2021

The COVID-19 pandemic has kept many of us at home for the past year or so, whilst all public activities were cancelled. But it also has a positive side. Whilst the National Cryptologic Museum (NCM) — the NSA's museum at Fort Meade (USA) — was closed to the public and plans for a new building were put on ice, it was decided to take the opportunity to renovate the existing building.

The renovation works are currently underway, whilst the curators and registrars are combing through the entire collection to see if any objects require maintenance or special attention. And their efforts have already payed off. Last month, the museum registrar rediscovered two machines that had not been spotted before or that had been forgotten, probably because no information was available about them when they were acquired.

The image on the right shows an extremely rare Russian K-37 cipher machine – probably the only surviving one – that was rediscovered last month.

The machine had probably been captured during World War II, and was used by the AFSA – the forerunner of the NSA – for analysis and codebreaking. The K-37 was a copy of the Hagelin B-211 and was adapted for the Cyrillic alphabet. It is shown here with the external plugboard in a wooden box attached to it. This is the first time a colour photograph of this machine is made public. Interestingly, the black & white photograph of a K-37 that was shown in Boris Hagelin's memoirs — the only existing photograph of a K-37 until now — was made of this very machine.

In addition to the K-37, the people at the NCM also found a complete and intact OMI Criptograph, an Italian cipher machine that was made around 1954 and that was based on the design of the German Enigma. It was believed that none of the original machines had survived and all that was left was a black & white photograph in a 1954 NSA report that was declassified in May 2014.

The final curtain?
14 June 2021

It a sad picture. The once so big and famous Swiss company Crypto AG — once the pride of the Swedish inventor Boris Hagelin, and succeeded in 2018 by Swedish entrepreneurs Andreas and Emma Linde under the name Crypto International AG — has dimissed nearly all of its staff and has moved its legal seat to the nearby town of Hünenberg. It seems that the curtain is falling.

Following the revelations of the American, German and Swiss media — the Washington Post, ZDF and SRF — in February 2020, that Crypto AG was owned from 1970 onwards b the German BND and the American CIA, and from 1994 onwards solely by the CIA, the Swiss Parliament ordered an official investigation.

As fall-out of the news, the Swiss Government withdrew the export licence of the company, and Linde was left no other choice than to layoff the entire workforce in July of last year. Alledgedly they filed for bankruptcy the following month.

With only two remaining staff members, the company left the buildings in Steinhausen early this year and moved its legal seat to nearby Hünenberg. A few months ago, on 1 April, professional photographer Patrick Hürlimann of Steinhausen took the photograph shown above. The buildings are now abandonned and will soon be taken down to make room for hausing development.

The International Cryptology Game
25 October 2020

Great news from Poland. The next edition of the CODEBREAKERS International Cryptology Game is about to start. The game is dedicated to Polish mathematicians who broke the code of the well-known German Enigma cipher machine, which is now 88 years ago. The secret work of the Polish mathematicians contributed considerably to the success and victory of the Allies during WWII.

The game will be released in six languages — English, French, Spanish, German, Polish and Russian — and combines elements of history, mathematics and logic in an accessible way. By learning about encryption and decryption methods, the participants solve virtual puzzles and break increasingly difficult secret messages.

It is worth noting that everyone can enter the game, as long as they can read. There are three levels of difficulty: TRIAL, BASIC, ADVENTURE. Prior knowlege about breaking ciphers is not required. Depending on the level of difficulty, each team may consists of 1, 2 or 3 people.

Mass layoffs at Crypto International AG
4 July 2020

According to the Swiss newspaper Neue Züricher Zeitung (NZZ), Crypto International AG (CIAG), announced yesterday that it will lay off 83 of its 85 staff, which is nearly the entire work­force. CIAG was established two years ago by Swedish entrepreneurs Emma and Andreas Linde, when they purchased part of the product portfolio of the former Crypto AG (Hagelin).

In February, journalists from the Washington Post, German televion ZDF and Swiss television SRF, had revealed that for many years, the equipment from Crypto AG has been manipulated by BND and CIA, under the name Operation RUBICON. Following these revelations, the Swiss Government has withdrown the export licence of CIAG and has announced a formal criminal investigation.

The intelligence coup of the century
11 February 2020

For many years it has been speculated that the cipher machines of Crypto AG (Hagelin) have exploitable weaknesses (backdoors) that can be used by Western intelligence services to break encrypted messages. From the Friedman Collection we already knew that a secret unwritten Gentleman's Agreement existed between Hagelin and the American NSA from 1951 onwards.

But the actual story is almost unimaginable. Investigative journalists of the German TV station ZDF, and the American newspaper Washington Post, have now discovered that in 1970, Crypto AG was secretly purchased by the German Bundesnachrichtendienst (BND) and the American Central Intelligence Agency (CIA) in a covert operation named RUBICON. For several decades it enabled NSA – and its German sister ZfCh - to read nearly all diplomatic traffic of the countries that were on the CIA/NSA target list.

 Learn more

Over the course of the next few days and weeks, several news media will report about Operation RUBICON, starting tonight with the German ZDF television program Frontal-21, And tomorrow morning, the US newspaper The Washington Post will give a detailed account of the operation. Crypto Museum will provide detailed technical backgrounds at a later moment. Coming soon...

Enigma. We have got news.
6 December 2019

It is widely known that the Poles were the first to break the Enigma cipher, and that – just before the outbreak of WWII – they shared their know­ledge with French and British intelligence, during a secret meeting in Pyry (Poland). However, the exact details of the Pyry meeting have so far never been found in French or British archives.

In this video, Polish writer Marek Grajek presents new facts about the breaking of Enigma, based on files disclosed by French intelligence in 2016, and comments on it together with Sir Dermot Turing and Prof. Philippe Guillot.
