In 1974, the British government admitted that its WWII secret
intelligence organization had read Germany''s ciphers on a massive
scale. The intelligence from these decrypts influenced the
Atlantic, the Eastern Front and Normandy. Why did the Germans never
realize the Allies had so thoroughly penetrated their
communications? As German intelligence experts conducted numerous
internal investigations that all certified their ciphers'' security,
the Allies continued to break more ciphers and plugged their own
communication leaks. How were the Allies able to so thoroughly
exploit Germany''s secret messages? How did they keep their
tremendous success a secret? What flaws in Germany''s organization
allowed this counterintelligence failure and how can today''s
organizations learn to avoid similar disasters? This book, the
first comparative study of WWII SIGINT Signals Intelligence,
analyzes the characteristics that allowed the Allies SIGINT success
and that fostered the German blindness to Enigma''s compromise.
