Cryptography And The World Wars The History Of Codemaking And Codebreaking During Both Global Conflicts Charles River Editors by Charles River Editors B0DPRBMMT7 instant download after payment.

Nearly every conceivable terrain saw use as a battlefield: the neat farmland and small towns of Western Europe; the streets of major cities; thick forests; open steppes stretching for hundreds of miles; deserts in Africa; rugged mountain ranges; and many other regions of the globe. But one of the war's most crucial struggles happened in the realm of the unseen, inside the human mind and amid the invisible flow of radio waves. Every war is a battle of wits as intelligence-gathering, tactics, and strategies clash, from the level of individual action up to the grand, overarching schemes of generals and statesmen. Intelligence took on a freshly urgent aspect in the Great War, however, as the fates of offensives, armies, and nations came to hang on the struggle to decrypt vital enemy radio traffic and military communications.

During the Second World War, cryptography suddenly became a significant factor in warfare because of mid 20th-century advances in communications technology. With radios small and common enough to be fitted into most individual vehicles and readily carried in a man-portable form, information and orders flowed from supreme headquarters to individual squad leaders, tanks, and soldiers at the front and back again.

Complex radio networks connected armies to their other elements almost like a nervous system, making unprecedented tactical and strategic coordination between units hundreds of miles apart not only possible but swift and, in some cases, efficient. Decrypting these signals or protecting their contents from enemy spying became one of the touchstones of victory or defeat. “Information warfare”
