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.
An adversary makes use of a MAC in an effort to modify both the Tag (the ciphertext) and the MAC (message authentication code). What are some of the possible outcomes if I performed this? In the event that this attack is successful, the receiver will always be capable to recognising a changed 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 if an attacker tries to tamper with the Tag (the MAC) and the ciphertext while they are in transit when a message authentication code (MAC) is being used? Give an explanation as to why this attack can never be successful, given that the ability of the target to identify a tampered Tag/ciphertext ensures that it will succeed every time.
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 results may be expected in the event that an attacker attempts to change a communication while it is in motion by modifying the Tag (MAC) and the ciphertext? Explain why the recipient will never miss a changed tag or ciphertext and why this attack will not succeed.
Is it possible for a threat actor to change both the encrypted data and the tag, which contains the MAC? Because the receiver can always determine if the Tag or ciphertext has been tampered with, this attack is fruitless.
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.
If an adversary attempts to tamper with the Tag (the MAC) and the ciphertext while the message is in transit, what will happen? The question is, what happens? Show us how and why this receiver will always recognize a changed tag, and explain why this attack is doomed to fail.
Using a MAC (message authentication code), is it feasible to change both the Tag (the MAC) and the ciphertext while they are in transit? In this attack, the receiver is able to always recognize a modified Tag/ciphertext; thus, explain why the attack will not be successful.
What happens if an adversary attempts to alter the Tag (the MAC) and the ciphertext of a communication that is using a MAC? Give reasons why the recipient would always be able to tell whether a tag or ciphertext had been tampered with.
