This phase should match following settings: The keying material used to derive keys for all SAs and to protect following ISAKMP exchanges between hosts is generated also. Phase 1 - The peers agree upon algorithms they will use in the following IKE messages and authenticate.In both cases, peers establish connection and execute 2 phases: IKE daemon responds to remote connection. The policy notifies IKE daemon about that, and IKE daemon initiates connection to remote host. There is some traffic caught by a policy rule which needs to become encrypted or authenticated, but the policy doesn't have any SAs. There are two possible situations when it is activated: Most of the time IKE daemon is doing nothing. Together they provide means for authentication of hosts and automatic management of security associations (SA). There are other key exchange schemes that work with ISAKMP, but IKE is the most widely used one. The Internet Key Exchange (IKE) is a protocol that provides authenticated keying material for Internet Security Association and Key Management Protocol (ISAKMP) framework. Encapsulating Security Payload (ESP) RFC 4303.Dynamically generates and distributes cryptographic keys for AH and ESP. Internet Key Exchange (IKE) protocols.IPsec protocol suite can be divided in following groups:
Internet Protocol Security (IPsec) is a set of protocols defined by the Internet Engineering Task Force (IETF) to secure packet exchange over unprotected IP/IPv6 networks such as Internet.
17.5 Site to Site GRE tunnel over IPsec (IKEv2) using DNS.17.2.7 Linux (strongSwan) client configuration.
17.2.6 Android (strongSwan) client configuration.17.2.2.1 Enabling dynamic source NAT rule generation.17.2.1.3 Generating client certificates.17.2 Road Warrior setup using IKEv2 with RSA authentication.16.4.2 Using same routing table with multiple IP addresses.
