WebIKEv1 specifies two significant negotiation phases for IKE and IPsec SA establishment: Phase 1: Establishes a bidirectional ISAKMP SA between two IKE peers. Once established, any peer can start phase 2 negotiations. Phase 2: Establishes unidirectional IPsec Security Associations (SAs) using the ISAKMP SA established in phase 1.

WebIKE, also called ISAKMP, is the negotiation protocol that lets two hosts agree on how to build an IPsec security association. ISAKMP separates negotiation into two phases: Phase 1 and Phase 2. Phase 1 creates the first tunnel, which protects la ter ISAKMP negotiation messages. Phase 2 creates the tunnel that protects data. WebThe IPsec (Phase 2) proposal occurs with both IKEv1 and IKEv2. In this phase, the two parties negotiate the type of security to use, which encryption methods to use for the traffic through the tunnel (if needed), and negotiate the lifetime of the tunnel before re-keying is needed.
