Read the excerpt from The Code Book.Alternatively, imagine that a bank receives an e-mail from a client, which instructs that all the client's funds should be transferred to a private numbered bank account in the Cayman Islands. Once again, without a handwritten signature, how does the bank know that the e-mail is really from the client? The e-mail could have been written by a criminal attempting to divert the money to his own Cayman Islands bank account. In order to develop trust on the Internet, it is essential that there is some form of reliable digital signature.

To evaluate the effectiveness of an argument, the reader needs to assess whether the author’s reasons and evidence are:
Read the paragraph about espionage.Governments use spies to find out secret information about enemies—or even allies—so they can make smart choices during tense times. Over the years, spies have used all kinds of clever tricks, from invisible ink and secret codes to modern computers and hidden cameras. Of course, spying isn’t all glamorous—it brings up tough questions about trust and privacy. For example, when one country secretly listens in on the private conversations of another country that it’s supposed to be friends with, it’s hard to tell whether that’s smart protection or a serious betrayal.
Read the quote from Zimmermann in The Code Book.A future government could inherit a technology infrastructure that's optimized for surveillance, where they can watch the movements of their political opposition, every financial transaction, every communication, every bit of e-mail, every phone call. Everything could be filtered and scanned and automatically recognized by voice recognition technology and transcribed. It's time for cryptography to step out of the shadows of spies and the military,
Read this paragraph from The Dark Game.Another thing that changed very little in the years between the wars was the means of obtaining military intelligence. Although the use of photography and the telegraph brought some technological advances, the craft of spying on the enemy's army still relied on fieldwork. For the most part, intelligence was gathered in simple ways. Prisoners of war and deserters were interrogated. The Union army was always interested in hearing what runaway slaves had to report. And, of course, both armies relied on cavalry scouts, signal intercepts, visual observation, and captured correspondence.
Read the excerpt from The Code Book.Other attacks include the use of viruses and Trojan horses. Eve might design a virus that infects PGP software and sits quietly inside Alice's computer. When Alice uses her private key to decrypt a message, the virus would wake up and make a note of it. The next time that Alice connects to the Internet, the virus would surreptitiously send the private key to Eve, thereby allowing her to decipher all subsequent messages sent to Alice.
A reader can ask, "How would I react if the events in this book happened to me?” to put a text into
Read the excerpt from The Code Book.More than a hundred million e-mails are sent around the world each day, and they are all vulnerable to interception. Digital technology has aided communication, but it has also given rise to the possibility of those communications being monitored.
Read the excerpt from The Dark Game.As a result of the cut cables, Germany lost its most secure long-distance communications system. The Germans now had to rely on radio transmissions from their powerful wireless station at Nauen, a few miles from Berlin. Which was exactly what the British military knew they would have to do. And once the Germans began sending wireless messages, MI8, the British code breakers, began plucking them from the air. Of course, all German correspondence was sent in a complicated cipher system, so that was when the hard work began for the code breakers of MI8.
Which excerpt from "The Enigma Machine” supports the claim that German soldiers accidentally helped the Allies figure out the Enigma codes?
Read the excerpt from "The Enigma Machine.”At Bletchley Park, the main site in Britain where Enigma codes were deciphered, six thousand messages were decoded every day by a staff of ten thousand men and women. Many of the messages were inconsequential, but more than a few were critical to the outcome of the war.
Read the excerpt from "The Enigma Machine.”Cryptologists looked for cribs, which are repeated expressions in messages. Sloppy operators would repeat phrases like "nothing to report" or "weather forecast" (Wettervorhersage), which served as clues. If there were no cribs to be found, the British would send out false information about, say, British mines planted in a given area. The Germans might then send messages with the name of that area, which would provide clues about deciphering that code.
Which excerpt from "The Enigma Machine” supports the idea that Allied forces expected the Germans to complicate their coding system?
Which best describes the author’s viewpoint about the people who learned to decipher the Enigma in "The Enigma Machine”?
Which best describes the author’s viewpoint toward the actual Rosetta Stone in "The Rosetta Stone”?
Read the excerpt from "The Rosetta Stone.”Egyptian scripts were replaced with Coptic, which included six demotic characters. In the ninth century, Arab scholar Abu Bakr Ahmad Ibn-Wahshiyah was able to partly decipher the hieroglyphs by comparing them to Coptic. But in the eleventh century, it too was replaced, by Arabic. The link was once again severed. For centuries, Western scholars tried to decipher the hieroglyphs, with little success. They were working under a false hypothesis, that the hieroglyphs were pictograms, with each symbol representing an object or an idea.
If someone were to describe "The Rosetta Stone” to a friend, he or she would most likely compare it to
Which evidence from "The Rosetta Stone” supports the claim that Thomas Young played a key role in helping to decipher the hieroglyphs on the Rosetta Stone?
