These two individuals are often used in cryptography examples to represent the parties trying to communicate securely
Who are Alice and Bob?
This term refers to the original unencrypted message that needs to be sent securely.
What is plaintext?
This is the term for the practice of deciphering encrypted information without access to the secret key.

This 'eavesdropper' represents the passive attacker who tries to listen in on communications between the good guys.
Who is Eve?
In symmetric-key cryptography, this is shared between two or more parties to allow them to maintain a private conversation.
What is a key?
This type of attack involves trying every possible key until the correct one is found.
What is a brute force attack?
Thailand shares borders with four nations. Which nation has the longest border with Thailand?

Who is Mallory?
Encrypt the plaintext message using the Caesar cipher with a right shift of 3: HELLO WORLD
