Selected Answer: C
o ECDH is considered the strongest encryption algorithm for initial key exchange in IPSec tunnels because it offers excellent security with relatively smaller key sizes compared to RSA. It is a key agreement protocol based on elliptic curve cryptography, providing a secure way for two parties to establish a shared secret key without ever revealing their private keys.
