Review the excerpt from The Code Book.In 1998, a report by Wayne Madsen revealed that the Swiss cryptographic company Crypto AG had built backdoors into some of its products, and had provided the U.S. Government with details of how to exploit these backdoors. As a result, America was able to read the communications of several countries. In 1991 the assassins who killed Shahpour Bakhtiar, the exiled former Iranian prime minister, were caught thanks to the interception and backdoor decipherment of Iranian messages encrypted using Crypto AG equipment.

Read the excerpt from The Code Book.Despite the enormous strength of RSA and other modern ciphers, cryptanalysts are still able to play a valuable role in intelligence gathering. Their success is demonstrated by the fact that cryptanalysts are in greater demand than ever before—the NSA is still the world's largest employer of mathematicians.

A
Many math experts work for the National Security Agency.
B
The RSA computer system makes our country more secure.
C
Skilled people are still important national security workers.
D
Computers are better than people at keeping the nation safe.

Review the excerpt from The Code Book.If Eve parks a van outside Alice's house, she can use sensitive tempest equipment to identify each individual keystroke that Alice makes on her computer. This would allow Eve to intercept the message as it is typed into the computer, before it is encrypted. To defend against tempest attacks, companies are already supplying shielding material that can be used to line the walls of a room to prevent the escape of electromagnetic signals.

A
why computers are easily stolen.
B
why keyboards are unsanitary.
C
how computer security can be broken.
D
how friends share secret messages.
