Oracle Solaris 11.2 introduces Internet Key Exchange (IKE) version 2 support. IKEv2 is the latest version of the preferred key management protocol for IPsec. IKEv2 provides automatic Security Association (SA) and key management between peer systems. The key exchanges are protected by a secure channel negotiated between the two peers. The peer's identity is established using either a pre-shared secret or public key certificates.
