German Cipher Machines of World War II by David Mowry Pdf

Along with breaking the Japanese diplomatic cryptosystem, usually referred to as "PURPLE," probably the greatest example of Allied cryptanalytic success in World War II was breaking of the German Enigma machine. This cryptodevice was used by all of the German armed forces as the primary cryptosystem for all units below Army level or the equivalent. As D-Day approached, other German cryptodevices, the SZ-42 and the various T-52 machines, assumed great importance since they were used by the higher commands of the German armed forces. Many references to these German machines in the histories fail to provide information on what they looked like or how they worked. Another group of cryptodevices, those invented by Fritz Menzer for the Abwehr (Counterintelligence), have received little or no notice in the literature and are unknown to the public. This brochure is an attempt to remedy both lacks.

Code Girls by Liza Mundy Pdf

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

X, Y and Z by Dermot Turing Pdf

December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

CryptoSchool by Joachim von zur Gathen Pdf

This book offers an introduction to cryptology, the science that makes secure communications possible, and addresses its two complementary aspects: cryptography—--the art of making secure building blocks—--and cryptanalysis—--the art of breaking them. The text describes some of the most important systems in detail, including AES, RSA, group-based and lattice-based cryptography, signatures, hash functions, random generation, and more, providing detailed underpinnings for most of them. With regard to cryptanalysis, it presents a number of basic tools such as the differential and linear methods and lattice attacks. This text, based on lecture notes from the author’s many courses on the art of cryptography, consists of two interlinked parts. The first, modern part explains some of the basic systems used today and some attacks on them. However, a text on cryptology would not be complete without describing its rich and fascinating history. As such, the colorfully illustrated historical part interspersed throughout the text highlights selected inventions and episodes, providing a glimpse into the past of cryptology. The first sections of this book can be used as a textbook for an introductory course to computer science or mathematics students. Other sections are suitable for advanced undergraduate or graduate courses. Many exercises are included. The emphasis is on providing reasonably complete explanation of the background for some selected systems.

Seizing the Enigma by David Kahn Pdf

“An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).

Big Machines by Stephen J. Kelley Pdf

Why do some cryptographic systems fail and others succeed? Stephen Kelley's new book, Big Machines, explores this fundamental question of cryptology by examining the history of three of the most renowned cipher systems of World War II - the German Enigma, the Japanese PURPLE, and the American SIGABA/ECM - to understand why the first two were broken by the allies and last remained unbroken. Were the allies' successes against Enigma and PURPLE due to inherent weaknesses in the Axis' machines, to poor communications security procedures, to physical compromise, or to all three? Was their failure to break the SIGABA/ECM due to the strength built into the American cipher or to Axis cryptanalytic incompetence? Big Machines investigates the histories of these three cryptosystems - how they were designed, how they were used, and how they were attacked by hostile cryptanalysts. Mr. Kelley compares the strengths and weaknesses inherent in each machine, and considers external factors influencing their ultimate security. Big Machines helps explain the allies overwhelming victory in the critical information war with Germany and Japan. Aegean Park Press is pleased to offer this unique and valuable addition to the literature of both cryptology and the Second World War.

Lorenz by Jerry Roberts Pdf

The breaking of the Enigma machine is one of the most heroic stories of the Second World War and highlights the crucial work of the codebreakers of Bletchley Park, which prevented Britain's certain defeat in 1941. But there was another German cipher machine, used by Hitler himself to convey messages to his top generals in the field. A machine more complex and secure than Enigma. A machine that could never be broken. For sixty years, no one knew about Lorenz or 'Tunny', or the determined group of men who finally broke the code and thus changed the course of the war. Many of them went to their deaths without anyone knowing of their achievements. Here, for the first time, senior codebreaker Captain Jerry Roberts tells the complete story of this extraordinary feat of intellect and of his struggle to get his wartime colleagues the recognition they deserve. The work carried out at Bletchley Park during the war to partially automate the process of breaking Lorenz, which had previously been done entirely by hand, was groundbreaking and is recognised as having kick-started the modern computer age.
