2) Let us assume there are two entities A and B, entity A wants to exchange his message (message is ABCD1234) with entity B. Entity A plans to encrypt his message with key = 1011010110101. Assume the key is shared with entity B. Identify the type of encryption and decryption. a) How will entity A will encrypt the message with the given key. Perform the necessary operation of encryption and show the ciphertext b) How A can decrypt the ciphertext to get the original message sent by entity A.

Choose the most accurate statement: The relationship between the key and the ciphertext is hidden via diffusion. The relationship between the key and the ciphertext is obscured by confusion. The plaintext-ciphertext link is obscured by confusion. The key and ciphertext influence confusion and diffusion. Confusion and Diffusion are created by all cyphers.
