1. Which of the following are valid key sizes for AES (choose three)?

2. Which of the following algorithms uses three different keys to encrypt the plain text?

3. Encryption of the same plain text with the same key results in the same cipher text. Use of an IV that is XORed with the first block of plain text solves this problem.

4. Which of the following is a protocol for exchanging keys?

5. Cylinder tool. Wrap leather around to decode. The diameter is the key. Used in 7th century BC by greek poet Archilochus.

6. The reverse process from encoding - converting the encoded message back into its plaintext format.

7. Hash. Created by Ronald Rivest. Replaced MD4. 128 bit output size, 512 bit block size, 32 bit word size, 64 rounds. Infamously compromised by Flame malware in 2012.

8. What is Kerchoff's principle?

9. Which one of the following is an algorithm that uses variable length key from 1 to 256 bytes, which constitutes a state table that is used for subsequent generation of pseudorandom bytes and then a pseudorandom string of bits, which is XORed with the plaintext to produce the ciphertext?

10. Basic information theory is the basis for modern symmetric ciphers. Understanding the terminology of information theory is, therefore, important.

If a single change of a single bit in the plaintext causes changes in all the bits of the resulting ciphertext, what is this called?
