Is it feasible to modify the Tag (the MAC) and the ciphertext using a MAC (message authentication code) while they are in transit? In this attack, the receiver can always recognize a modified Tag/ciphertext; thus, explain why it cannot succeed.

Suppose a user employs one-time passwords as above (or, for that matter, reusable passwords), but that the password is transmitted sufficiently slowly. (a) Show that an eavesdropper can gain access to the remote server with a relatively modest number of guesses. (Hint: The eavesdropper starts guessing after the original user has typed all but one character of the password.) (b) To what other attacks might a user of one-time passwords be subject?

The attacker uses the MAC to try to alter the Tag (the encrypted message) (message authentication code). Exactly what are the potential outcomes if I do this? If this attack succeeds, the target will always be able to spot a tampered Tag or ciphertext.

Is it feasible to modify the Tag (the MAC) and the ciphertext using a MAC (message authentication code) while they are in transit? In this attack, the receiver can always recognize a modified Tag/ciphertext; thus, explain why it cannot succeed.

What happens when a MAC (message authentication code) is utilised and an attacker tries to tamper with the Tag (the MAC) and the ciphertext while it is in transit? Explain why this attack can never succeed since the target's ability to identify a modified Tag/ciphertext ensures success.

Can an attacker using a MAC modify the Tag (the MAC) and the encrypted data? This attack is hopeless since the recipient can always identify whether the Tag/ciphertext has been tampered with.

What happens if a potential attacker tries to alter the Tag (the MAC) and the ciphertext while they are in transit, using a MAC (message authentication code)? Please elaborate on why this attack is pointless given that the receiver will detect a modified Tag/ciphertext.

Is it feasible to modify the Tag (the MAC) and the ciphertext using a MAC (message authentication code) while they are in transit? In this attack, the receiver can always recognize a modified Tag/ciphertext; thus, explain why it cannot succeed.

When a MAC (message authentication code) is used, what happens if an attacker attempts to tamper with the Tag (the MAC) and the ciphertext while in transit? Provide an explanation for why this attack can never succeed since the target's ability to detect a tampered Tag/ciphertext guarantees success.

What happens if an attacker attempts to alter the Tag (the MAC) and ciphertext while the message is in transit? What happens? Let us know how and why this attack will fail; that is, we must show how and why this receiver will always recognize that the tag has been changed.
