Q: Define the following terms:-
a. Brute force attack
b. message integrity
c. shared key
d. Monoalphabet cipher

Solution

a. Brute force attack: An attack in which the attacker tries to determine the key/password by trying all possible values, with no intelligence/prior knowledge on what it could be.

b. Message Integrity: The message integrity assures that the message is recieved by the receiver as it is sent by the sender, and no modification is done in transit.

c. Shared Key: It is the concept in which the key is shared between the two parties in a way such that only they can decrypt the encrypted data/message.

d. Monoalphabet cipher: This is the concept used to encrypt the message in a way such that, every occurence of a character is replaced by some other character, but the replacement will be the same for every occurence of a character. For example every b is replaced with x, or something like that.
