(Internet|IPSEC) Key Exchange
It comes from IPSEc, which is an extension (of sorts) to the IP protocol
that adds encryption. Public/private key encryption is used to set up
the session key, very similar to SSL, which is also the way a lot of VPN
softwares do it. So IKE is the way the two machines involved in the
IPSEC/VPN session xfer their public keys so that they can establish the
session key that actually is used for the encrypted session.
You might also see things like ISAKMP/Oakley, SKIP, ESP, and other weird
acronyms. They all have to do with various key-exchange and session
management techniques used by IPSEC and shared by a lot of VPN
softwares.
http://www.ietf.org/html.charters/ipsec-charter.html
is a good location for references to a lot of IPSEC-related info.
