DH – Diffie-Hellman Key Exchange
The Diffie-Hellman Key Exchange is the process in which cryptographic keys may be distributed between communicating parties across a public IP network. Diffie-Hellman was considered to be a significant advancement in cryptography and has been adopted in numerous cryptographic processes. In particular, IKE uses Diffie-Hellman key exchange to help establish an IPSec security association.
