WG of the IETF.

   Title           : Comparison of CoAP Security Protocols

   This document analyzes and compares the sizes of key exchange flights
   and the per-packet message size overheads when using different
   security protocols to secure CoAP.  The described overheads are
   independent of the underlying transport.  Small message sizes are
   very important for reducing energy consumption, latency, and time to
   completion in constrained radio network such as Low-Power Wide Area
   Networks (LPWANs).  The analyzed security protocols are DTLS 1.2,
   DTLS 1.3, TLS 1.2, TLS 1.3, cTLS, EDHOC, OSCORE, and Group OSCORE.
   The DTLS and TLS record layers are analyzed with and without 6LoWPAN-
   GHC compression.  DTLS is analyzed with and without Connection ID.
