"Cryptology has gone public," Kahn writes. "A field that was once the exclusive domain of governments has become a concern of businesses and individuals."In this absorbing and eclectic collection, Kahn expertly explores the crytographer's world, leading us into and through its dark labyrinths. We learn about the legendary Herbert O. Yardley's "lost manuscript," investigate the origins of polyalphabetic substitution, and follow the adventures of Hans-Thilo Schmidt- whom Kahn calls the greates spy of World War II.Among the other fascinating sections in Kahn on Codes: * Codebreaking in World Wars I &amp; II: Their Major Successes and Failures, Their Causes and Effects * Lgcn Otuu Wllwgh W1 Etfown, or, "They Will Attack at Midway" * Ciphers and Computers * The Soviet Spy Ciphers used by Reino Hayhanen and Rudolf Abel * Public Versus Private Cryptology * Codes in Context * Opportunities in CryptologyKahn on Codes also includes a list of cryptological terms, endnotes, and index.
