Alan Turing Will Be on the New £50 Note Soon!

turing3_sculpture-photo2

When it comes to influential puzzlers, it’s hard to top the impact mathematician and codebreaker Alan Turing had on the world.

Admittedly, there are numerous names — too numerous to mention, really — associated with the ENIGMA project and Bletchley Park’s codebreaking efforts in general that deserve recognition. World War II was shortened by YEARS by the work of the folks at Bletchley Park, and Alan Turing was a pivotal figure in the war effort.

And he has been selected as the face of the new £50 note for British currency.

The Bank of England received over 227,000 suggestions of British scientists to appear on the new version of the note, and Turing was selected from the shortlist of 12 official nominees, a list that included Rosalind Franklin, James Clerk Maxwell, Dorothy Hodgkin, Mary Anning, Paul Dirac, Srinivasa Ramanujan, and Stephen Hawking, as well as pairs like Ada Lovelace and Charles Babbage and William and Caroline Herschel.

Naturally the Queen will still appear on the front of the note, and Turing on the reverse side, replacing former note design figures as James Watt, Matthew Boulton, and Christopher Wren.

But the elevation of Alan Turing isn’t just a victory for a historical figure or a puzzling icon, it’s one for the LGBTQ+ community as well. Because of his sexuality, Turing was forced out of his work at the GCHQ — Britain’s governmental codebreaking operation — and driven to suicide by government persecution and abuse.

After a campaign led by numerous British luminaries like Richard Dawkins, Stephen Fry, and Peter Tachell, an apology was issued by then prime minister Gordon Brown in 2009. A posthumous pardon by the Queen in 2013 followed.

These acts don’t undo the crimes of the past. But they are a symbolic promise for the future that anyone like Turing — no matter their historical importance, social status, or personal choices — will not endure the same horrors that he did.

Nearly 70 years after he and his colleagues helped bring an end to World War II, Turing will continue to inspire and impact the world as a face on the £50 note. That’s something to celebrate.

A Video Game Puzzle Hunt Reaps Real-World Rewards!

We’ve written about some pretty amazing and elaborate puzzle hunts here in the past. There was the Gravity Falls cipher hunt that led to an actual statue of the show’s villain Bill Cipher in the woods of Reedsport, Oregon. (And a mayoral position for the first person to find him and shake his hand!) There was the puzzle-turned-global-scavenger hunt from Trials Evolution that won’t be completed until 2113 at the base of the Eiffel Tower.

And now, a massive crowdsourcing effort has cracked another masterpiece, a puzzle hidden in an expansion pack for the video game Destiny 2. Destiny 2 is an online first-person-shooter loaded with sci-fi trappings and in-depth storytelling where players explore a shared environment while engaging in their own personal plot and adventures.

The most recent expansion to the game, Warmind, was released last week, and players noticed an elaborate symbol on a wall in the bunker of Rasputin, a sentient robot. The symbol appeared to be a lock surrounded by keys and curious symbols.

This Kotaku post went live on Friday, three days after the Warmind release, revealing the incredible online effort already in motion to unravel the secrets of the Rasputin puzzle. The subreddit r/raidsecrets was ground zero for the puzzle-solving efforts, and players compiled their theories and discoveries there.

Players quickly determined that each of the keys had a symbol that linked back to other imagery from the game, and by following those breadcrumbs, they had a chance to crack the cipher.

The first symbol was found in several places, each time with a set of digits and a bar in a particular position. Solvers theorized that these symbols represented the word “reverse.”

The second symbol appeared beside a Braille grid, leading hunters to crates with Braille lettering on them: OEAARRTFWTH. This anagrams to The Art of War, Sun Tzu’s famous tome. In this case, The Art of War was used as the source material for an Ottendorf Cipher. (That particular cipher was made famous by Nicolas Cage’s National Treasure movies.)

This type of cipher uses numbers in groups of three, and these numbers correspond to positions of letters in a book. Most often the numbers refer to Line, Word, and Letter. Decoding the number-combinations in the image above led to the answer “Destroy all second A and B. Then destroy all third C and R.”

These two clues were assumed to be instructions for what to do with the encoded ciphertext others had discovered in the game:

This encrypted message was the heart of the puzzle. But there was more to uncover first.

As it turns out, the last three keys in the image represented different words to apply to the ciphertext in order to properly decode it.

The fourth symbol was found near a Morse Code sequence that spelled out “NTEHNMLNEEGIT,” an anagram for “Enlightenment.”

The fifth symbol pointed toward a monitor with some peculiar code on it. It turns out the code was actually Jianpu, an ancient form of Chinese notation for writing music. When translated into actual music, a player identified the piece as an excerpt from Tchaikovsky’s Swan Lake.

One intrepid codebreaker then tried to decrypt the ciphertext given the clues everyone had assembled thus far.

He reversed the ciphertext, according to the instruction of the first key. He then removed every other A and every other B from the text, then every third C and every third R, according to the instructions of the second key.

Then, employing a Vigenere cipher, he used the two key words he had — “enlightenment” and “swan lake” — to begin decrypting the text. He managed to decrypt the entire text, but more incredibly, he also reverse engineered the missing third key word — “mechanized” — while doing so.

And what was the final message, after all this?

thank you for taking the time to piece together this message, friend. the time of our final conflict is drawing closer and you and ana have an important role to play in the events to come. so watch over her, guardian. i would have no life without ana or the exoprogram. i regret that we have become strangers, but we each have a path that we must walk. and, ironically, there never seems to be enough time. tell her, rasputin’s first attempt was in the right location, but the wrong moment. look here: 43.549573, -73.544868 – e

As you might suspect, those numbers at the end are GPS coordinates, which correspond to Sleeping Beauty Mountain in upstate New York. (The company that developed Warmind, Vicarious Visions, is based in upstate New York.)

A small treasure trove of prizes awaited the brave soul who trekked out to Sleeping Beauty Mountain on Saturday morning. The centerpiece was a giant spear, a replica of a weapon from the game known as the Valkyrie.

From the Kotaku article following up on the puzzle’s resolution:

There was also a box of gold coins (along with instructions asking the finder to only take one), a set of notes, and a journal for recording visitors. The note, from Warmind design lead Rob Gallerani, encouraged the finder(s) to share photos of this discovery and told them that there are only three spears like that in existence — one at Vicarious Visions, one at Bungie, and this.

The spear, shown above (alongside the visiting team from Vicarious Visions) now resides at a comic shop called The Freakopolis Geekery.

As for the gold coins and the geocache Vicarious Visions had set up for others who make the trip, unfortunately, park rangers removed it because the designers didn’t get a permit. The coins have been returned to Vicarious Visions, who are currently reaching out to all the folks at r/raidsecrets who contributed to the solution of the puzzle, hoping to get them the coins they so richly deserve.

And, as if all that wasn’t amazing enough, it turns out… this might not be the end of the adventure.

Because a sharp-eyed observer noticed some text embossed on the upper portion of the replica Valkyrie spear:

At the moment, no one knows what the letters mean. But if I had to wager, I’d say the master puzzle solvers at r/raidsecrets should keep digging. Who knows what they’ll find next?

Elizebeth Smith Friedman, Codebreaker and Scourge of Nazi Spymasters

[William and Elizebeth Smith Friedman, hard at work.

Last year, I rather ambitiously attempted to summarize the early history of American codebreaking and the NSA in a series of blog posts spanning World War II through the modern day. One of the names I cited in that series, William Friedman, is synonymous with American cryptography, thanks to his contributions to the cracking of the German ENIGMA code and his efforts to establish the National Security Agency.

Unfortunately, there is a gaping hole in the narrative I constructed. Because none of my sources made any reference to another crucial Friedman: Elizebeth Smith Friedman, William’s wife and partner in code-cracking.

Yes, she was name-dropped in my post about the book Code Girls: The Untold Story of the American Women Code Breakers of World War II, but she had to share those pages with a host of underappreciated women who were codebreaking geniuses.

[Image courtesy of HarperCollins Publishers.]

As The Woman Who Smashed Codes explains, she wasn’t just a talented codebreaker. She literally wrote the book on it. Eight of them, in fact. The Riverbank Publications — although often credited to her husband — covered new codebreaking techniques in rich detail, and they are still referred to today as part of the foundation of modern cryptography.

She also started the first and only American codebreaking unit ever run by a woman, serving as Cryptanalyst-in-Charge while jointly working for both the Treasury and the Coast Guard during and after World War II.

A history of American codebreaking without Elizebeth Smith Friedman is woefully incomplete, and in today’s post, I hope to rectify that oversight.

[Image courtesy of the Marshall Foundation.]

Elizebeth’s work with codes started in a most peculiar way. While seeking a job as a librarian after college, she was recruited by eccentric millionaire George Fabyan to live and work at Riverbank, his palatial estate that doubled as a self-funded research center for all sorts of scientific endeavors.

Elizebeth’s deep knowledge of Shakespeare was put to work attempting to prove Fabyan’s theory that there were secret messages encoded in the writings of Shakespeare. Although her work failed to uncover any hidden pattern in Shakespeare’s words or font choices, it did lead to two unexpected developments: a career in codebreaking and a budding romance with fellow Riverbank recruit William Friedman, whose own interest in codebreaking was sparked by the works of Edgar Allan Poe.

Thanks to the proliferation of radio, there was a seismic shift in how information was being passed between military units, governments, and other organizations, so the ability to listen in on one’s enemies (and allies) was not only a new strategic opportunity, but it was a relatively new science.

In short, America needed codebreakers who could crack the secret messages being transmitted (and intercepted). The military didn’t have them. The government didn’t have them.

But Riverbank did. And for the first eight months of World War I, the small group of William, Elizebeth, and those they trained handled ALL of the codebreaking for every part of the US government, from the State Department to the Army to the DOJ. William and Elizebeth began running a codebreaking school out of Riverbank, even embedding a secret message in a photo of the class taken on the last day of the course.

[Images courtesy of Elonka.com.]

In the aftermath of the First World War, codebreaking had become so important that countries were turning to machines to help develop uncrackable codes. And yet, at this point, American cryptography as a whole consisted of about 50 people. William went to work for the government, establishing the American version of Bletchley Park — Arlington Hall — and setting the stage for the creation of the NSA.

Elizebeth, on the other hand, cracked codes from home. And she did so for both the Treasury Department and the Coast Guard, who would send her sealed packages of intercepted encrypted intel and communications. In her first three months hunting down rum-runners during Prohibition, she solved two years’ worth of backlogged messages.

During World War II, Elizebeth’s Coast Guard Cryptography Unit turned their attention from smuggling (which waned during wartime) to cracking German codes. Under her tutelage, they would crack three different variations on the Enigma codes, each more complex than the last. (The British also cracked ENIGMA, independently of American efforts.)

Sadly, in the aftermath of the Pearl Harbor attack, the US military didn’t want civilians in charge of sensitive operations, so Elizebeth was demoted. Yes, she was no longer in charge of the group she started, trained, and cultivated, instead answering to a new boss of dubious cryptographic talents.

(Of course, the sexist dimwits making decisions like this had to grin and bear it when numerous other organizations and agencies continued to asked for Elizebeth’s assistance by name.)

And stealing Elizebeth’s credit was practically a cottage industry over at the FBI. We have them to thank for erasing Elizebeth’s role in particular — and the Coast Guard’s role in general — in hunting down, exposing, and compromising Nazi spy networks in South America, even though the FBI’s hamfisted blundering actually served to expose codebreaking operations in the past, forcing Elizebeth to crack new codes in order to regain the advantage the FBI had squandered.

Oh, yeah, did I mention that both during AND after World War II, Elizebeth continued to hound the Nazi forces in South America who sought to destabilize the region?

As one historian put it, referring to the thousands of pages of decryptions Elizebeth produced:

These pieces of paper saved lives. They almost certainly stopped coups. They put fascist spies in prison. They drove wedges between Germany and other nations that were trying to sustain and prolong Nazi terror. By any measure, Elizebeth was a great heroine of the Second World War.

The British knew it. The navy knew it. The FBI knew it. But the American public never did, because Elizebeth wasn’t allowed to speak.

Even in their retirement, the Friedmans continued to contribute to the world of cryptography. They returned to the subject of Shakespeare with The Shakespeare Ciphers Examined, thoroughly debunking the whole idea of hidden codes in the Bard’s works.

When William died, Elizebeth even hid a secret message on his tombstone, for those who knew how to look. (It was Bacon’s cipher, something they both studied extensively during their time at Riverbank.) What a touching tribute to how she met her partner and husband.

And although the accolades and appreciation for Elizebeth’s incredible contributions have been slow in coming, they are trickling in. In the 1990s, the NSA renamed its auditorium from the William F. Friedman Memorial Auditorium to the William F. Friedman and Elizebeth S. Friedman Memorial Auditorium. A Justice Department building also has an auditorium bearing her name.

More information about the massive expansion of codebreaking worldwide is coming to light with every passing year. Hopefully that will mean greater attention for minds like Elizebeth, who used her puzzly mind to protect the world. That’s someone worth celebrating.

[Much of the information in this post comes from a wonderful book on Elizebeth, The Woman Who Smashed Codes by Jason Fagone, and it’s well-worth your time to check out her story in full.]

The Voynich Manuscript: Finally Cracked?

[Image courtesy of BBC.com.]

A year and a half ago, I introduced my fellow puzzlers and PuzzleNationers to the Voynich Manuscript, a cryptologic curiosity unlike anything else we’ve seen before. Discovered over a hundred years ago but believed to date back to the fifteenth century, the Voynich Manuscript is a hand-written book that has baffled linguists and puzzlers for decades.

The writing, which reads from right to left, has yet to be identified. It’s unclear if this is some sort of sophisticated code, an unknown or lost language which was then encoded, an invented language, an example of glossolalia (a written equivalent of speaking in tongues), or simply an elaborate hoax.

The only known copy of the text resides in Yale University’s Beinecke Rare Book and Manuscript Library, although Yale has printed replica texts.

From the Yale University website:

Many call the fifteenth-century codex, commonly known as the “Voynich Manuscript,” the world’s most mysterious book. Written in an unknown script by an unknown author, the manuscript has no clearer purpose now than when it was rediscovered in 1912 by rare books dealer Wilfrid Voynich. The manuscript appears and disappears throughout history, from the library of the Holy Roman Emperor Rudolf II to a secret sale of books in 1903 by the Society of Jesus in Rome. The book’s language has eluded decipherment, and its elaborate illustrations remain as baffling as they are beautiful.

[One of several fold-out pages in the manuscript.

But computer scientists at the University of Alberta believe they’ve finally unraveled some of the mysteries behind the Voynich Manuscript.

They designed an artificial intelligence program with the intent of figuring out the language in the manuscript. The AI analyzed versions of the UN’s Universal Declaration of Human Rights in 400 different languages in order to establish different linguistic patterns to compare against the text of the Voynich Manuscript.

And according to the AI, the text was most likely written in Hebrew.

Now that they had a language to work with, they needed to begin deciphering precisely how that language was encrypted.

[Image courtesy of Wikipedia.org.]

There have been many theories regarding what form of encryption was employed in the Voynich Manuscript. Some investigators theorized that vowels had been removed from the words in the text in order to obscure their meaning further, while others have suggested writing that has been mirrored or otherwise written backwards. Anagrams and other forms of word manipulation are a common theory, and the University of Alberta team went with a variation on the anagram idea.

They theorized that the encoded words were alphagrams, anagrams where the letters in a word are placed in alphabetical order. (For instance, if VOYNICH was encoded this way, it would read CHINOVY.)

Turning loose the AI once again under these parameters, they found that 80% of the words in the Voynich text could be anagrammed into Hebrew words. They managed to cobble together a possible opening sentence for the text:

“She made recommendations to the priest, man of the house and me and people.”

Is it clunky? Sure. But it’s also a partial translation that has held up to some scrutiny, which is better than most amateur AND professional attempts to crack the Voynich Manuscript have done.

The team is currently hoping to team up with experts in ancient Hebrew and continue the process, but until then, they’re excited to apply their AI to other ancient manuscripts to see what it uncovers.

Although we are a long way from calling the Voynich mystery solved, this is a very intriguing step forward for cryptographers and codebreaking enthusiasts everywhere.

Unsung Tales of Women in American Code Breaking!

[Image courtesy of Amazon.]

Dot Braden. Agnes Driscoll. Betty Hyatt. Elizebeth Friedman. Genevieve Grotjan. Ann Caracristi. Virginia Aderholdt. Ruth “Crow” Weston.

You don’t know these names, but you should. Everyone should. They’re bona fide American heroes who dedicated their time and energy to protecting not only our country, but also every soldier in the Allied forces during World War II. And they did so when they should have otherwise been continuing their collegiate studies.

That’s right, these women who came from majors as diverse as botany, math, psychology, and English, were recruited out of college in order to build a dedicated code-breaking unit for the US armed forces.

Thankfully, their stories are now being told in Liza Mundy’s new book, Code Girls: The Untold Story of the American Women Code Breakers of World War II. And these are some amazing stories.

It all started in early 1942, as secret letters began showing up in college mailboxes. Schools like Bryn Mawr, Mount Holyoke, Barnard, Radcliffe, and more posed two questions to prospective female recruits:

1. Did she like crossword puzzles?
2. Was she engaged to be married?

All of these women replied yes, they like crossword puzzles, and no, they’re not engaged or soon-to-be engaged.

After answering these questions, the women began attending introductory meetings. They were issued manila envelopes containing “a brief introduction to the arcane history of codes and ciphers, along with numbered problems sets and strips of paper with the letters of the alphabet printed on them.”

Their orders? Complete the problem sets every week.

[Image courtesy of YouTube.]

Each packet contained one problem that could not be solved, to show that sometimes, a jumble of letters or numbers doesn’t stand for anything. Sometimes, gibberish remains just that, because sometimes a code-breaker fails.

They developed working knowledge of foreign languages they didn’t speak. They memorized the most common English letters — E, T, O, N, A, I, R, S — and took frequency counts.

And that’s how America built its answer to England’s Bletchley Park code-breaking operation. (The American effort, known as Arlington Hall, was considered by their Bletchley Park rivals as “just a lot of kids playing at ‘office’.”)

College presidents like Ada Comstock, the president of Radcliffe College (the women’s counterpart to Harvard), were recruited to identify candidates to learn cryptanalysis to help shorten the war.

And make no mistake, they did shorten the war. They helped crack Enigma, which was key to decimating the German U-boat fleet, and their code-breaking efforts were instrumental in defeating Japan as well, providing valuable intel on the island-to-island battles of the Pacific theater.

[Image courtesy of Military Factory.]

Of the US Army’s World War II code-breaking force, nearly 70 percent was female. We’re talking 7,000 female code-breakers. When you factor in US Navy recruits as well, that number jumps to 11,000 women out of 20,000 code-breakers.

From Code Girls: “Code breaking required literacy, numeracy, care, creativity, painstaking attention to detail, a good memory, and a willingness to hazard guesses. It required a tolerance for drudgery and a boundless reserve of energy and optimism.”

Genevieve Grotjan was key to cracking the Japanese cipher known as Purple, and William Friedman, the man who initially ran the Arlington Hall operation, described the Purple cipher as “by far the most difficult cryptanalytic problem successfully handled and solved by any signal intelligence organization in the world.” He specifically pointed to the contrbutions of Grotjan, Mary Louise Prather, and other women in the Arlington Hall group.

Codes used by twenty-five different nations were analyzed by Arlington Hall, including codes of friends and foes alike. “There was a French code called Jellyfish, a Chinese enciphered code they called Jabberwocky, another they called Gryphon.”

But even their staggering efforts in code-breaking weren’t all they contributed to the cause. They were also crucial to the success of the D-Day invasion, as many of the women were put to work reverse-engineering messages in order to create false information about imaginary troop movements and landing areas. And in order to create fake signal traffic, they had to know the real traffic backward and forward.

I could go into more detail, breaking down how they cracked some of the war’s most important code languages, or exploring their personal lives and how life changed for these college students-turned-military operatives, but I don’t want to reveal more than I have already.

Read Code Girls. You won’t regret it. It’s another terrific entry in a year of books full of revelations about wartime puzzle history. We’ve been taken behind the scenes of the NSA, Bletchley Park, and now Arlington Hall.

And once more, important and influential female voices are getting the limelight far later than they deserve. It’s about time.
