Internet Key Exchange Protocol version 2 (IKEv2), specified in [RFC7296], provides a way for two parties to perform an authenticated key exchange. While the authentication methods used by the peers can be different, there is no method for one or both parties to remain unauthenticated and anonymous. This document extends the authentication methods to support unauthenticated and anonymous IKE sessions.

                      The NULL Authentication Method         in the Internet Key Exchange Protocol Version 2 (IKEv2)


   This document specifies the NULL Authentication method and the    ID_NULL Identification Payload ID Type for Internet Key Exchange    Protocol version 2 (IKEv2).  This allows two IKE peers to establish    single-side authenticated or mutual unauthenticated IKE sessions for    those use cases where a peer is unwilling or unable to authenticate    or identify itself.  This ensures IKEv2 can be used for Opportunistic    Security (also known as Opportunistic Encryption) to defend against    Pervasive Monitoring attacks without the need to sacrifice anonymity.
