IKEv2 – Internet Key Exchange Protocol Version 2

IKEv2 is a component of IPsec used for performing mutual authentication and establishing and maintaining Security Associations (SAs). These SAs include shared secret information that can be used to efficiently establish SAs for ESP (Encapsulating Security Payload) or AH (Authentication Header) and a set of cryptographic algorithms to be used by the SAs to protect the traffic that they carry. With IKEv2, a SA is first established in order to protect and transport IKEv2 traffic. After this point, Child SAs can then be established in order to protect other traffic types.
