There is a possibility that end-to-end encryption will be an issue with application-level proxies. Give some thought to how an application-level proxy may deal with encrypted payloads and offer some solutions.

Application-level proxies may need end-to-end encryption. Suggest an application-level proxy's encrypted payload handling.

A. Define network protocols.  B. Describe the TCP packet generation on the sender side throughout the layers with a supporting diagram.   Attach File

Using a MAC (message authentication code), what happens if an attacker attempts to tamper with the Tag (the MAC) and the ciphertext while in transit? The recipient would be able to spot a tampered Tag/ciphertext, thus please explain why this attack is futile.

Which encryption benchmark ensuresdata is not modified after it’s transmittedand before it’s received?

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.

End-to-end encryption decryption may be problematic for application-level proxies. Provide a solution that will allow an application-level proxy to transit a protocol whose payloads are encrypted.X

For application-level proxies, end-to-end encryption might be a concern. Make a suggestion on how an application-level proxy may handle encrypted payloads.

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.

What happens if an attacker uses a MAC to modify a communication's Tag (MAC) and ciphertext while it is in transit? Explain why the recipient will always detect a modified Tag or ciphertext and why this attack fails.
