Technical Summary

This document defines a new authentication mechanism for IKEv2, appropriately called "NULL". The
NULL mechanism allows two IKE peers to establish either single-side or mutual authentication for
those use cases where a peer is unwilling or unable to authenticate or identify itself. This is
useful for using IPsec with opportunistic security without the need to sacrifice anonymity. The
document also defines a new identification type, ID_NULL.
