- A . CA
- B . TGS
- C . OCSP
- D . TGT

Attempting to crack encryption by simply trying as many randomly generated keys as possible is referred to as what?
- A . Rainbow table
- B . Frequency analysis
- C . Brute force
- D . Kasiski
Which one of the following best describes a process that splits the block of plaintext into two separate blocks, then applies the round function to one half, and finally swaps the two halves?
- A . Block ciphers
- B . Symmetric cryptography
- C . Feistel cipher
- D . Substitution cipher
A _____ is a function that takes a variable-size input m and returns a fixed-size string.
- A . Feistel
- B . Asymmetric cipher
- C . Symmetric cipher
- D . Hash
Basic information theory is the basis for modern symmetric ciphers. Understanding the terminology of information theory is, therefore, important.

- A . Complete diffusion
- B . Complete scrambling
- C . Complete confusion
- D . Complete avalanche
