Question

Answer 2

$\huge\bold{\underline{Answer:-}}$

Link encryption differs from end-to-end encryption mainly in the fact that it encrypts and decrypts all traffic at every point, no just at the end points. With this approach, all data is in an encrypted state while it travels on its communication path.
