End$-$to$-$end authentication and encryption are desired between two hosts. Draw figures similar to Figure $8\mathrm{.}8$ in the PLE $($Figure $9\mathrm{.}8$ in the textbook$)$ that show each of the following.

$1)$Transport adjacency with encryption applied before authentication.

$2)$A transport SA bundled inside a tunnel SA with encryption applied before authentication.

$3)$A transport SA bundled inside a tunnel SA with authentication applied before encryption.
