After being uneasy allies in World War II, the 1950s saw the United States and the Soviet Union entering the Cold War, a thirty-year conflict in which the adversaries never went into physical battle with each other but fought many proxy wars in other nations. This gripping and fast-paced book traces the Cold War through the lens of spying and code breaking by showing how advances in computer technology and mathematics kept the technology race every bit as nerve-racking as the arms race that characterized the conflict.

Set against the backdrop of the Cold War, the conflict in Vietnam was much more than a battle between Vietnamese and American forces. Although the fighting may have taken place in monsoon-swept cities and booby-trapped jungles, the Vietnam War was fought on a much larger scale. Spies were active on all fronts, including within the United States itself. Readers will explore how technology and tactics not only shaped the Vietnam War, but changed the ethics of American surveillance from then until the present day.

Following on from the enormous success of his bestseller, The Secret Life of Bletchley Park, renowned author Sinclair McKay uncovers the story of what happened after the end of the Second World War. Once victory was declared, many of the individuals who had achieved the seemingly impossible at Bletchley Park by cracking the impenetrable Enigma codes and giving the Allies an invaluable insight directly into the Nazi war machine, moved on to GCHQ. This was the British government’s new facility established to fight a different, but no less formidable foe – Stalin and the KGB. Fascinating and insightful revelations from deep within the archives of this secret organisation reveal the story of the tumultuous early years of GCHQ as it navigated its way through an era of double agents, deception and betrayals. From the defection of the Cambridge Five and the treachery of the atomic scientist Klaus Fuchs, to the collapse of the British Empire, the ascension of Chairman Mao and the emergence of the US as a superpower, McKay deftly explores the impact these events had on the fledgling organisation. During the years of the Cold War the men and women of GCHQ penetrated Soviet encryptions and gathered crucial intelligence from all over the world. The Spies of Winter tells the story of the codebreakers themselves and how they used new technology to expand the horizons of cryptography in order to defend the nation and maintain the fragile peace in a world now under the shadow of nuclear holocaust.

Code breakers and spies are the stuff of legend and intrigue, but in reality, they dramatically impacted wars and influenced society, as well as altered the field of information technology. Technology during the 1940s was primitive by today's standards, but spying and cryptography were cutting edge for the time. Many have heard of the use of Navajo code talkers during World War II, but this text explores the code talkers and beyond to paint a vivid picture of how cryptography and spy technology shaped the conflict.

Learn of the importance of espionage and intelligence as a factor in international events, such as World War Two, and the Cold War. Full of fascinating information on codes and codebreakers, and the role of spies, in both a historical context, and today.

In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.

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.
