Read the excerpt from The Dark Game.As Montgomery and de Grey slowly made their way through the message, they noticed more and more oddities. For example, 97556 appeared near the end of the message; the 90000 family indicated important names that were not used very often in messages. We can imagine their shock when they realized that 97556 stood for Zimmermann. That single name fired the men with excitement as they began working on the message from the beginning.

Read the excerpt from The Code Book.A theoretical breakthrough would be a fundamentally new way of finding Alice's private key. Alice's private key consists of p and q, and these are found by factoring the public key, N. The standard approach is to check each prime number one at a time to see if it divides into N, but we know that this takes an unreasonable amount of time.

Read the excerpt from The Dark Game: True Spy Stories from Invisible Ink to CIA Moles.Wyke's work was always delicate and demanding, more so in the damp and confined space. Gently and carefully, Wyke scraped the dirt until he found the three cables encased in black rubber and, he believed, pressurized by nitrogen, a common practice in the 1950s to keep moisture out of cables. He knew that once he cut through the rubber sheathing on the cables, the nitrogen would escape. The resulting drop in pressure would be detected by the Soviets. The engineers solved this potential problem by building a concrete barrier with a steel door to pressurize the tap chamber and separate it from the pre-amp room. (It turned out that the cables were not pressurized.)Wyke next attached wires to the exposed cable—probably with alligator clips—and began to draw power from the cables. Once again, the work called for a deft hand. If he drew off too much power, the Soviets would be sure to notice it. As expected, Wyke did a masterful job, and the tapping began on May 11, 1955.

Read the excerpt from The Code Book.The difference between ordinary and digital mail can be illustrated by imagining that Alice wants to send out invitations to her birthday party, and that Eve, who has not been invited, wants to know the time and place of the party. If Alice uses the traditional method of posting letters, then it is very difficult for Eve to intercept one of the invitations. . . .In comparison, Eve's task is made considerably easier if Alice sends her invitations by e-mail.

Read this paragraph from The Dark Game.It may seem surprising that no Confederate sympathizers took action against Van Lew, given her strong and public views on secession and slavery. Surely there were suspicions, especially among her upper-crust neighbors, but the matter never went beyond those suspicions. Historians have suggested that the secessionists were victims of their own cultural bias, believing that no aristocratic person, and certainly not a lady, would ever consider taking part in anything as impolite as spying. A true lady managed her servants, prepared parties and gatherings, and blindly supported her husband. Such attitudes worked in Van Lew's favor, diverting suspicion from her.
