Internet Key Exchange (IKE)

IKE is a hybrid protocol that provides utility services for IPSec: authentication of the IPSec peers, negotiation of IKE and IPSec security associations, and establishment of keys for encryption algorithms used by IPSec.

NOTE

IKE is synonymous with ISAKMP in Cisco router or PIX Firewall configurations.
