IKE (Internet Key Exchange)
The protocol used to handle encryption keys in IPSec-based VPNs.
IKE performs several functions including authenticating endpoints of VPN tunnels, deciding which encryption and authentication algorithms would be used in a session, generating encryption keys and managing them.
The Internet Engineering Task Force is currently looking at alternatives to IKE, which has a theoretical risk of being used in denial-of-service attacks.
