 Almost all peer-to-peer communications in GNUnet are between mutually
 authenticated peers.  The authentication works by using ECDHE, that is a
 DH key exchange using ephemeral eliptic curve cryptography.  The ephemeral

 man-in-the-middle attacks will not break the authentication or accounting
 goals.  Essentially, for GNUnet, the IP of the host has nothing to do with
 the identity of the host.  As the public key is the only thing that truly
