Hi,

- Included overhead of DTLS with Connection ID with and without compression. Happy to report that GHC works perfectly with Connection ID. The overhead seems to grow only with the length of the Connection ID. A new table gives an overview of overhead of DTLS/OSCORE with different sizes of Connection ID/Sender ID.

- Updated the OSCORE section to align with draft-ietf-core-object-security-06 and added the payload marker.

- Updated the summary.

Cheers,
John

    Abstract:
       This document analyzes and compares per-packet message size overheads
       when using different security protocols to secure CoAP.  The analyzed
       security protocols are DTLS 1.2, DTLS 1.3, TLS 1.2, TLS 1.3, and
       OSCORE.  DTLS and TLS are analyzed with and without compression.
       DTLS are analyzed with two different alternatives for header
       compression as well as with and without Connection ID.

    
    Please note that it may take a couple of minutes from the time of submission
    until the htmlized version and diff are available at tools.ietf.org.
