Available in PDF, EPUB and Kindle. Book excerpt: For the first time, the inside story of the brilliant American engineer who defeated Enigma and the Nazi code-masters Much has been written about the success of the British “Ultra” program in cracking the Germans’ Enigma code early in World War II, but few know what really happened in 1942, when the Germans added a fourth rotor to the machine that created the already challenging naval code and plunged Allied intelligence into darkness. Enter one Joe Desch, an unassuming but brilliant engineer at the National Cash Register Company in Dayton, Ohio, who was given the task of creating a machine to break the new Enigma settings. It was an enterprise that rivaled the Manhattan Project for secrecy and complexity–and nearly drove Desch to a breakdown. Under enormous pressure, he succeeded in creating a 5,000-pound electromechanical monster known as the Desch Bombe, which helped turn the tide in the Battle of the Atlantic–but not before a disgruntled co-worker attempted to leak information about the machine to the Nazis. After toiling anonymously–it even took his daughter years to learn of his accomplishments–Desch was awarded the National Medal of Merit, the country’s highest civilian honor. In The Secret in Building 26, the entire thrilling story of the final triumph over Enigma is finally told.
Book Synopsis A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics by : George Lasry
Download or read book A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics written by George Lasry and published by kassel university press GmbH. This book was released on 2018 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptography, the art and science of creating secret codes, and cryptanalysis, the art and science of breaking secret codes, underwent a similar and parallel course during history. Both fields evolved from manual encryption methods and manual codebreaking techniques, to cipher machines and codebreaking machines in the first half of the 20th century, and finally to computerbased encryption and cryptanalysis from the second half of the 20th century. However, despite the advent of modern computing technology, some of the more challenging classical cipher systems and machines have not yet been successfully cryptanalyzed. For others, cryptanalytic methods exist, but only for special and advantageous cases, such as when large amounts of ciphertext are available. Starting from the 1990s, local search metaheuristics such as hill climbing, genetic algorithms, and simulated annealing have been employed, and in some cases, successfully, for the cryptanalysis of several classical ciphers. In most cases, however, results were mixed, and the application of such methods rather limited in their scope and performance. In this work, a robust framework and methodology for the cryptanalysis of classical ciphers using local search metaheuristics, mainly hill climbing and simulated annealing, is described. In an extensive set of case studies conducted as part of this research, this new methodology has been validated and demonstrated as highly effective for the cryptanalysis of several challenging cipher systems and machines, which could not be effectively cryptanalyzed before, and with drastic improvements compared to previously published methods. This work also led to the decipherment of original encrypted messages from WWI, and to the solution, for the first time, of several public cryptographic challenges.

Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field. FEATURES Presents a chronological development of key concepts Includes the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s wheel cipher, Playfair cipher, ADFGX, matrix encryption, Enigma, Purple, and other classic methods Looks at the work of Claude Shannon, the origin of the National Security Agency, elliptic curve cryptography, the Data Encryption Standard, the Advanced Encryption Standard, public-key cryptography, and many other topics New chapters detail SIGABA and SIGSALY, successful systems used during World War II for text and speech, respectively Includes quantum cryptography and the impact of quantum computers
Download or read book Unsolved! written by Craig P. Bauer and published by Princeton University Press. This book was released on 2019-06-18 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers"--
Download or read book Seizing the Enigma written by David Kahn and published by Frontline Books. This book was released on 2012-02-02 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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).

Book Synopsis Coding Theory and Cryptography by : David Joyner
Download or read book Coding Theory and Cryptography written by David Joyner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: These are the proceedings of the Conference on Coding Theory, Cryptography, and Number Theory held at the U. S. Naval Academy during October 25-26, 1998. This book concerns elementary and advanced aspects of coding theory and cryptography. The coding theory contributions deal mostly with algebraic coding theory. Some of these papers are expository, whereas others are the result of original research. The emphasis is on geometric Goppa codes (Shokrollahi, Shokranian-Joyner), but there is also a paper on codes arising from combinatorial constructions (Michael). There are both, historical and mathematical papers on cryptography. Several of the contributions on cryptography describe the work done by the British and their allies during World War II to crack the German and Japanese ciphers (Hamer, Hilton, Tutte, Weierud, Urling). Some mathematical aspects of the Enigma rotor machine (Sherman) and more recent research on quantum cryptography (Lomonoco) are described. There are two papers concerned with the RSA cryptosystem and related number-theoretic issues (Wardlaw, Cosgrave).
Book Synopsis Learning and Experiencing Cryptography with CrypTool and SageMath by : Bernhard Esslinger
Download or read book Learning and Experiencing Cryptography with CrypTool and SageMath written by Bernhard Esslinger and published by Artech House. This book was released on 2023-12-31 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad overview of cryptography and enables cryptography for trying out. It emphasizes the connections between theory and practice, focuses on RSA for introducing number theory and PKI, and links the theory to the most current recommendations from NIST and BSI. The book also enables readers to directly try out the results with existing tools available as open source. It is different from all existing books because it shows very concretely how to execute many procedures with different tools. The target group could be self-learners, pupils and students, but also developers and users in companies. All code written with these open-source tools is available. The appendix describes in detail how to use these tools. The main chapters are independent from one another. At the end of most chapters, you will find references and web links. The sections have been enriched with many footnotes. Within the footnotes you can see where the described functions can be called and tried within the different CrypTool versions, within SageMath or within OpenSSL.
Book Synopsis War of Shadows by : Gershom Gorenberg
Download or read book War of Shadows written by Gershom Gorenberg and published by PublicAffairs. This book was released on 2021-01-19 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this World War II military history, Rommel's army is a day from Cairo, a week from Tel Aviv, and the SS is ready for action. Espionage brought the Nazis this far, but espionage can stop them—if Washington wakes up to the danger. As World War II raged in North Africa, General Erwin Rommel was guided by an uncanny sense of his enemies' plans and weaknesses. In the summer of 1942, he led his Axis army swiftly and terrifyingly toward Alexandria, with the goal of overrunning the entire Middle East. Each step was informed by detailed updates on British positions. The Nazis, somehow, had a source for the Allies' greatest secrets. Yet the Axis powers were not the only ones with intelligence. Brilliant Allied cryptographers worked relentlessly at Bletchley Park, breaking down the extraordinarily complex Nazi code Enigma. From decoded German messages, they discovered that the enemy had a wealth of inside information. On the brink of disaster, a fevered and high-stakes search for the source began. War of Shadows is the cinematic story of the race for information in the North African theater of World War II, set against intrigues that spanned the Middle East. Years in the making, this book is a feat of historical research and storytelling, and a rethinking of the popular narrative of the war. It portrays the conflict not as an inevitable clash of heroes and villains but a spiraling series of failures, accidents, and desperate triumphs that decided the fate of the Middle East and quite possibly the outcome of the war.
Download or read book The Rohonc Code written by Benedek Láng and published by Penn State Press. This book was released on 2021-04-08 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: First discovered in a Hungarian library in 1838, the Rohonc Codex keeps privileged company with some of the most famous unsolved writing systems in the world, notably the Voynich manuscript, the Phaistos Disk, and Linear A. Written entirely in cipher, this 400-year-old, 450-page-long, richly illustrated manuscript initially gained considerable attention but was later dismissed as an apparent forgery. No serious scholar would study it again until the turn of the twenty-first century. This engaging narrative follows historian Benedek Láng’s search to uncover the truth about this thoroughly mysterious book that has puzzled dozens of codebreakers. Láng surveys the fascinating theories associated with the Codex and discusses possible interpretations of the manuscript as a biblical commentary, an apocryphal gospel, or a secret book written for and by a sect. He provides an overview of the secret writing systems known in early modern times and an account of the numerous efforts to create an artificial language or to find a long-lost perfect tongue—endeavors that were especially popular at the time the Codex was made. Lastly, he tests several codebreaking methods in order to decipher the Codex, finally pointing to a possible solution to the enigma of its content and language system. Engagingly written, academically grounded, and thoroughly compelling, The Rohonc Code will appeal to historians, scholars, and lay readers interested in mysteries, codes, and ciphers.
Book Synopsis The History of Information Security by : Karl Maria Michael de Leeuw
Download or read book The History of Information Security written by Karl Maria Michael de Leeuw and published by Elsevier. This book was released on 2007-08-28 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information Security is usually achieved through a mix of technical, organizational and legal measures. These may include the application of cryptography, the hierarchical modeling of organizations in order to assure confidentiality, or the distribution of accountability and responsibility by law, among interested parties. The history of Information Security reaches back to ancient times and starts with the emergence of bureaucracy in administration and warfare. Some aspects, such as the interception of encrypted messages during World War II, have attracted huge attention, whereas other aspects have remained largely uncovered. There has never been any effort to write a comprehensive history. This is most unfortunate, because Information Security should be perceived as a set of communicating vessels, where technical innovations can make existing legal or organisational frame-works obsolete and a breakdown of political authority may cause an exclusive reliance on technical means.This book is intended as a first field-survey. It consists of twenty-eight contributions, written by experts in such diverse fields as computer science, law, or history and political science, dealing with episodes, organisations and technical developments that may considered to be exemplary or have played a key role in the development of this field.These include: the emergence of cryptology as a discipline during the Renaissance, the Black Chambers in 18th century Europe, the breaking of German military codes during World War II, the histories of the NSA and its Soviet counterparts and contemporary cryptology. Other subjects are: computer security standards, viruses and worms on the Internet, computer transparency and free software, computer crime, export regulations for encryption software and the privacy debate. - Interdisciplinary coverage of the history Information Security- Written by top experts in law, history, computer and information science- First comprehensive work in Information Security
Book Synopsis Very Special Intelligence by : Patrick Beesly
Download or read book Very Special Intelligence written by Patrick Beesly and published by Pen and Sword. This book was released on 2015-06-02 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational Intelligence Centre was the nerve centre of the British Admiralty in World War II, dedicated to collecting, analyzing and disseminating information from every possible source which could throw light on the intentions and movements of German naval and maritime forces. OIC labored tirelessly, despite early disappointments, to supply the Navy and RAF with the intelligence that would enable them to defeat Hitler and his admirals. Patrick Beesly, an insider drawing on considerable personal knowledge, reveals, in full, the compelling story of OIC. He throws light on dramatic episodes such as the hunt for the Bismarck; the tragedy of Convoy PQ17; the long war against the U-boats; and on many other significant events critical to the course of the war. Very Special Intelligence, here presented with a new Introduction which sets the work in context and takes account of new research, is the fascinating story of an organization which contributed so much to Allied success.
Book Synopsis The Gambler and the Scholars by : John F. Dooley
Download or read book The Gambler and the Scholars written by John F. Dooley and published by Springer Nature. This book was released on 2023-04-05 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 1917, William and Elizebeth Friedman were asked by the U.S. Army to begin training officers in cryptanalysis and to decrypt intercepted German diplomatic and military communications. In June 1917, Herbert Yardley convinced the new head of the Army’s Military Intelligence Division to create a code and cipher section for the Army with himself as its head. These two seminal events were the beginning of modern American cryptology, the growth of which culminated 35 years later with the creation of the National Security Agency. Each running their own cryptologic agencies in the 1920s, the Friedman-Yardley relationship was shattered after Yardley published a tell-all book about his time in military intelligence. Yet in the end, the work they all started in 1917 led directly to the modern American intelligence community. As they got older, they became increasingly irrelevant in the burgeoning American cryptologic fraternity. Topics and features: * Examines the lives of three remarkable and pioneering cryptologists * Offers fascinating insights into spies, codes and ciphers, rumrunners, poker, and military history * Sheds new light on interesting parts of the cryptologists’ careers—especially Elizebeth Friedman, whose work during World War II has just begun to be explored * Recounts several good stories, i.e., What if the Friedmans had gone to work for Herbert Yardley in his new Cipher Bureau in 1919? What if Yardley had moved back to Washington to work for William Friedman a decade later? This enjoyable book has wide appeal for: general readers interested in the evolution of American cryptology, American historians (particularly of World War I, the inter-war period, and World War II signals intelligence), and historians of—and general readers interested in—American military intelligence. It also can be used as an auxiliary text or recommended reading in introductory or survey courses in history or on the related topics.
Book Synopsis Science and the Pacific War by : Roy M. MacLeod
Download or read book Science and the Pacific War written by Roy M. MacLeod and published by Springer Science & Business Media. This book was released on 1999-12-31 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1995, the fiftieth anniversary of the end of the Second World War occasioned many reflections on the place of science and technology in the conflict. That the war ended with Allied victory in the Pacific theatre, inevitably focussed attention upon the Pacific region, and particularly upon the Manhattan project and its outcome. It was in the Pacific that Western physics and engineering gave birth to the Atomic Age. However, the Pacific war had also proved a testing time, and a testing space, for other disciplines and institutions. Extreme environments and opemtional distances, and the fundamental demands of logistics, required the Allies and the Japanese to innovate many scientific and technological practices. Just as medicine and botany were called upon to fight tropical diseases and insect pests, so engineers, anthropol ogists and geographers were called upon to understand local conditions and cli mates, and to work with local peoples whose traditional lives were changed forever by the experience. At the same time, the war played midwife to a host of new de velopments, not least in scientific intelligence and in chemical and biological weapons, which were to acquire far greater importance after 1945.
