For IKEv1, the phase 1 negotiation that takes place between two IKE peers happens in one of two modes, Main mode or Aggressive mode. Main mode is more secure because it encrypts the identities of the two hosts that are contained in the IKE messages, but somewhat slower because more message exchanges are required.

Main Mode Message-1: The very 1st packet is sent by Initiator Tunnel Endpoint to Responder Tunnel Endpoint. This message contains the proposal of the Security Association which contains the Encryption, Hashing, Authentication, DH group, and Lifetime. Also, this message contains the Initiator cookie.

Using IKE to negotiate VPNs between two endpoints provides more security than the manual key exchange. Manual key exchange?IPsec supports using and exchanging of keys manually (example: phone or email) on both sides to establish VPN.

Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie?Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.

IKE version 2 is an enhancement to the Internet key exchange protocol. IKE version 2 (IKEv2) was developed by the IETF with RFC4306. IKEv2 enhances the function of negotiating the dynamic key exchange and authentication of the negotiating systems for VPN.

The Internet Key Exchange version 2 (IKEv2) Protocol dynamically establishes and maintains a shared state between the end-points of an IP datagram. IKEv2 performs mutual authentication between two parties and establishes the IKEv2 Security Association (SA).

The original version of IKE sets up secure communications channels in two phases: phase 1 and phase 2. In phase 1, an authenticated connection between the host and user is established using a preshared key or a digital certificate. The goal is to secure the communications that occur in phase 2.

Internet Key Exchange (IKE) is a secure key management protocol that is used to set up a secure, authenticated communications channel between two devices. IKE does the following: Negotiates and manages IKE and IPsec parameters. Authenticates secure key exchange.

To configure key exchange settings In the details pane on the main Windows Defender Firewall with Advanced Security page, click Windows Defender Firewall Properties. On the IPsec Settings tab, click Customize. In the Key exchange (Main Mode) section, click Advanced, and then click Customize.

The IKE protocol uses UDP packets, usually on port 500, and generally requires 4?6 packets with 2?3 round trips to create an ISAKMP security association (SA) on both sides. The negotiated key material is then given to the IPsec stack.
