Can link and end-to-end encryption both be used on the same communication? What would be the advantage of that? Cite a situation in which both forms of encryption might be desirable.
What will be an ideal response?
Yes. More sensitive communications might be protected with end-?to-?end encryption carried through a lower-?sensitivity link encrypted pipe. Or a company might implement end-?to-?end encryption of email at the application level, without knowing that the pathway would be encrypted (e.g., not all paths would necessarily be link encrypted).
