This post is giving you the details of research, purpose, and key features in Internet Key exchange (IKE).

Overview

• In computing, Internet Key Exchange (IKE, sometimes IKEv1 or IKEv2, depending on version) is the protocol used to set up a security association (SA) in the IPsec protocol suite.

Key features

• Auto create a new key
• Protecting on attacks which block the circuit like DDos (Denial-of-service attack)
• Using digital key
• Using the same key
• Providing means for both partners to agree on protocols, algorithms, and keys to use.
• Make sure the key exchange goes to the right user
• Managing keys after being accpeted
• Allow dynamic endorsement between peer objects.

Purpose

• Internet key exchanged uses to set up a secure, authenticated communications channel between two devices.
• During key exchange, IKE uses a symmetric encryption algorithm, these keys will be changed over time -> limit the cracking status of attackers
