What best describes the shifting of each letter a fixed number of spaces to the left or right?
- A . Single substitution
B. Multi substitution
C. XOR
D. Bit shifting
Suggested Answer: A
Explanation:
Single substitution
https://en.wikipedia.org/wiki/Substitution_cipher#Simple_substitution
Substitution of single letters separately―simple substitution―can be demonstrated by writing out the alphabet in some order to represent the substitution. This is termed a substitution alphabet. The cipher alphabet may be shifted or reversed (creating the Caesar and Atbash ciphers, respectively) or scrambled in a more complex fashion, in which case it is called a mixed alphabet or deranged alphabet.
