Answer:
C. ASCII code
Explanation:
Reflected code is another term for gray code so you can cross both out.
BCD code is binary decimal code used in scientific and graphic calculators
ASCII code is the only one use in a computer keyboard so I'm guessing that's the answer. :)
If you play the Wii, they have the controller and then they have a nunchuck that connects to the other controller, and you use that with your other hand. Hope that helps :)
Answer:
(a)
Assuming the one-time pad P is used to XOR the message M to get ciphertext C, the following holds:
M ⊕ P = C
P = C ⊕ M
this is a basic property of how XOR works.
(b)
P = M1 ⊕ C1
then M2 = C2 ⊕ P
(c)
The attacker can make assumptions about the message (e.g., presence of certain words and spaces) and then calculate which pad would be needed to get them in the ciphertexts. He then has two ciphertexts that should yield valid content, making it much more easy to guess the pad.
