Abstract:
   This draft describes the general problem of encryption of the Server
   Name Identification (SNI) parameter.  The proposed solutions hide a
   Hidden Service behind a Fronting Service, only disclosing the SNI of
   the Fronting Service to external observers.  The draft starts by
   listing known attacks against SNI encryption, discusses the current
   "co-tenancy fronting" solution, and then presents two potential TLS
   layer solutions that might mitigate these attacks.
   The first solution is based on TLS in TLS "quasi tunneling", and the
   second solution is based on "combined tickets".  These solutions only
   require minimal extensions to the TLS protocol.
