The Oakley Key Determination Protocol is a key-agreement protocol that allows authenticated parties to
exchange keying material across an insecure connection using the Diffie–Hellman key exchange algorithm.
The protocol was proposed by Hilarie K. Orman in 1998, and formed the basis for the more widely used
Internet key exchange protocol

IKE (Internet Key Exchange)
A key management protocol standard that is used in conjunction with the IPSec standard. IPSec is an IP
security feature that provides robust authentication and encryption of IP packets. IPSec can be configured
without IKE, but IKE enhances IPSec by providing additional features, flexibility, and ease of configuration for
the IPSec standard. IKE is a hybrid protocol that implements the Oakley key exchange and Skeme key
exchange inside of the Internet Security Association and Key Management Protocol (ISAKMP) framework.
ISAKMP, Oakley, and Skeme are security protocols implemented by IKE
