   This memo specifies Network Time Security (NTS), a mechanism for
   using Transport Layer Security (TLS) and Authenticated Encryption
   with Associated Data (AEAD) to provide cryptographic security for the
   client-server mode of the Network Time Protocol (NTP).

   NTS is structured as a suite of two loosely coupled sub-protocols.
   The first (NTS-KE) handles initial authentication and key
   establishment over TLS.  The second handles encryption and
   authentication during NTP time synchronization via extension fields
   in the NTP packets, and holds all required state only on the client
   via opaque cookies.
