EAP-IKEv2 is an EAP authentication method based on the Internet Key Exchange Protocol version 2 (IKEv2). It provides mutual authentication and session key establishment between an EAP peer and an EAP server. It supports authentication techniques that are based on the following types of credentials:

* Asymmetric key pairs - public/private key pairs where the public key is embedded into a digital certificate, and the corresponding private key is known only to a single party.
* Passwords - low-entropy bit strings that are known to both the server and the peer.
* Symmetric keys - high-entropy bit strings that known to both the server and the peer.
