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


  • 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.


  • 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
