{ "item_title" : "The Cryptographic Mathematics of Enigma", "item_author" : [" A. Ray Miller "], "item_description" : "The Enigma cipher machine had the confidence of German forces who depended upon its security. This misplaced confidence was due in part to the large key space the machine provided. This paper derives for the first time the exact number of theoretical cryptography key settings and machine configuration for the Enigma cipher machine. It also calculates the number of practical key settings Allied cryptanalysts were faced with daily throughout World War II. Finally, it shows the relative contribution each component of the Enigma added to the overall strength of the machine.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/47/837/927/1478379278_b.jpg", "price_data" : { "retail_price" : "11.99", "online_price" : "11.99", "our_price" : "11.99", "club_price" : "11.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
