   This document proposes a device pairing mechanism that establishes a
   relation between two devices by agreeing on a secret and manually
   verifying the secret's authenticity using an SAS (short
   authentication string).  Pairing has to be performed only once per
   pair of devices, as for a re-discovery at any later point in time,
   the exchanged secret can be used for mutual authentication.

   The proposed pairing method is suited for each application area where
   human operated devices need to establish a relation that allows
   configurationless and privacy preserving re-discovery at any later
   point in time.  Since privacy preserving applications are the main
   suitors, we especially care about privacy.
