RFC4081 - Security Threats for Next Steps in Signaling (NSIS)

                 Figure 1: Communication patterns in NSIS

   First-Peer/Last-Peer Communication:

      The end-to-end communication scenario depicted in Figure 1
      includes the communication between the end hosts and their nearest
      NSIS hops.  "First-peer communications" refers to the peer-to-peer
      interaction between a signaling message originator, the NSIS
      Initiator (NI), and the first NSIS-aware entity along the path.
      This "first-peer communications" commonly comes with specific
      security requirements that are especially important for addressing
      security issues between the end host (and a user) and the network
      it is attached to.

      To illustrate this, in roaming environments, it is difficult to
      assume the existence of a pre-established security association
      directly available for NSIS peers involved in first-peer
      communications, because these peers cannot be assumed to have any
      pre-existing relationship with each other.  In contrast, in
