Qu? es la criptograf?a cu?ntica La utilizaci?n de caracter?sticas mec?nicas cu?nticas para llevar a cabo operaciones criptogr?ficas es el campo de estudio conocido como criptograf?a cu?ntica. La aplicaci?n m?s conocida de la criptograf?a cu?ntica es la distribuci?n de claves cu?nticas, que proporciona una soluci?n segura, desde el punto de vista de la teor?a de la informaci?n, al problema del intercambio de claves. El beneficio de la criptograf?a cu?ntica radica en el hecho de que permite completar con ?xito una variedad de tareas criptogr?ficas que se ha demostrado o conjeturado que son imposibles utilizando solo la comunicaci?n cl?sica. Estas tareas incluyen el descifrado de mensajes que se han cifrado con una clave que ha sido robada. No es factible, por ejemplo, duplicar datos que han sido codificados en un estado cu?ntico. Si alguien hace un esfuerzo por leer los datos codificados, el estado cu?ntico se ver? alterado como resultado del colapso de la funci?n de onda. En la distribuci?n de claves cu?nticas, esto puede usarse para identificar escuchas en conversaciones (QKD). C?mo se beneficiar?

To break a code, you have to put yourself in the mind of your enemy in order to probe the strengths and weaknesses of their systems. It's a game of bluff and doublebluff. The Story of Codebreaking describes undercover operations, power struggles, secret alliances, and brilliant feats of teamwork. Those who invent codes and those who break them are remarkable, indefatigable characters. Find out how Mary Queen of Scots smuggled cryptic messages to her accomplices when she was plotting against her cousin Elizabeth I, or discover the methods used by codebreakers during World Wars I and II, most significantly those who cracked Enigma and intercepted Japanese naval messages prior to Pearl Harbor. The sheer doggedness of those who unraveled the Enigma code is thought to have shortened World War II by almost two years. Topics include: • Ancient ciphers and the art of encoding • Early spies, subterfuge and skytales • The making and breaking of Enigma • Japanese naval codes in World War II • Cold War cryptography

People throughout history have written messages in code and ciphers to guard and pass along closely held secret information. Today, countries around the world enlist cryptanalysts to intercept and crack messages to keep our world safe. Code Cracking for Kids explores many aspects of cryptology, including famous people who used and invented codes and ciphers, such as Julius Caesar and Thomas Jefferson; codes used during wars, including the Enigma machine, whose cracking helped the Allies gather critical information on German intelligence in World War II; and work currently being done by the government, such as in the National Security Agency. Readers also will learn about unsolved codes and ciphers throughout history, codes used throughout the world today, though not often recognized, and devices used over the years by governments and their spies to conceal information. Code Cracking for Kids includes hands-on activities that allow kids to replicate early code devices, learn several different codes and ciphers to encode and decode messages and hide a secret message inside a hollow egg.

The First Enigma Codebreaker is the story of a man who started a revolution in cryptology and the conflict between man and machine. This is a powerful story of the life of Marian Rejewski and how history can affect individual lives, presented to the public for the first time. This examination of how Marian Rejewski changed the course of cryptology is of great interest to everyone from the avid historian to Hollywood film producers and all those in-between. As Gawlowski’s biography shows, Rejewski was an unassuming man who used his mathematical, skills as well as his extensive linguistic abilities, to start cracking the Enigma code before passing the baton on to the now renowned Alan Turing. This is a fascinating, human story about the man Marian Rejewski, which also ties up the loose threads of the Enigma story and shows the importance of the Polish involvement in that process. The First Enigma Codebreaker looks at those involved in cracking the Enigma and also takes a look at an aspect that has rarely been discussed in great detail, the story of Marian Rejewski himself, and how he endured life in post-war Communist Poland shining a light on situations such as how Rejewski managed to decode the machine, what happened to him during the Second World War, and the price he had to pay during the post war period.

Before the multi-million, runaway bestseller The Da Vinci Code, Dan Brown set his razor-sharp research and storytelling skills on the most powerful intelligence organization on earth--the National Security Agency (NSA)--in this thrilling novel, Digital Fortress. When the NSA's invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls its head cryptographer, Susan Fletcher, a brilliant and beautiful mathematician. What she uncovers sends shock waves through the corridors of power. The NSA is being held hostage...not by guns or bombs, but by a code so ingeniously complex that if released it would cripple U.S. intelligence. Caught in an accelerating tempest of secrecy and lies, Susan Fletcher battles to save the agency she believes in. Betrayed on all sides, she finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves. From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. It is a battle for survival--a crucial bid to destroy a creation of inconceivable genius...an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.

"Success in dealing with unknown ciphers is measured by these four things in the order named: perseverance, careful methods of analysis, intuition, luck." So begins the first chapter of Colonel Parker Hitt's 1916 Manual for the Solution of Military Ciphers, a foundational text in the history of cryptology. An irrepressible innovator, Hitt possessed those qualities in abundance. His manual, cipher devices, and proactive mentorship of Army cryptology during World War I laid the groundwork for the modern American cryptologic system. Though he considered himself an infantryman, Hitt is best known as the "father of American military cryptology." In Parker Hitt: The Father of American Military Cryptology, Betsy Rohaly Smoot brings Hitt's legacy to life, chronicling his upbringing, multiple careers, ingenious mind, and independent spirit. In the 1910s, after a decade as an infantry officer, Hitt set his sights on aviation. Instead, he was drawn to the applied sciences, designing signal and machine-gun equipment while applying math to combat problems. Atypical for the time, Hitt championed women in the workplace. During World War I he suggested the Army employ American female telephone operators, while his wife, Genevieve Young Hitt, became the first woman to break ciphers for the United States government. His daughter, Mary Lue Hitt, carried on the family legacy as a "code girl" during World War II. Readers of Elizabeth Cobbs' The Hello Girls, Liza Mundy's Code Girls, and David Kahn's The Codebreakers will find in Parker Hitt's story an insightful profile of an American cryptologic hero and the early twentieth-century military. Drawing from a never-before-seen cache of Hitt's letters, photographs, and diaries, Smoot introduces readers to Hitt's life on the front lines, in classrooms and workshops, and at home.
