IPsec IKE: Internet Key Exchange
IPsec Internet Key Exchange (IKE) Protocol is a key protocol in the IPsec architecture. IKE processes can be used for negotiating virtual private networks (VPNs) and also for providing a remote user from a remote site (whose IP address need not be known beforehand) access to a secure host or network. IKE is a hybrid protocol using part of Oakley and part of SKEME in conjunction with ISAKMP to obtain authenticated keying material for use with ISAKMP, and for other security associations such as AH and ESP for the IPsec DOI.
