A DH key exchange is an algorithm that utilizes asymmetric cryptographic keys.
The DH key exchange is used to establish a shared secret over an insecure medium during an IPSec phase 1 exchange.
The DH exchange is susceptible to man-in-the-middle attacks.
The DH exchange is used to authenticate the peer device duringan IPSec phase 1 exchange.
A DH exchange provides Perfect Forward Secrecy （PFS）.
