Ballot Text

Technical Summary

   This document describes the minimal properties IP Encapsulating
   Security Payload (ESP) implementation needs to meet to remain
   interoperable with the standard RFC4303 ESP.  Such a minimal version
   of ESP is not intended to become a replacement of the RFC 4303 ESP.
   Instead, a minimal implementation is expected to be optimized for
   constrained environment while remaining interoperable with
   implementations of RFC 4303 ESP.  In addition, this document also
   provides some considerations to implement minimal ESP in a
   constrained environment which includes limiting the number of flash
   writes, handling frequent wakeup / sleep states, limiting wakeup
   time, or reducing the use of random generation.

   This document does not update or modify RFC 4303, but provides a
   compact description of how to implement the minimal version of the
   protocol.  RFC 4303 remains the authoritative description.

Working Group Summary

   There were several rounds of feedback, including from the incoming
   SEC AD.  Authors feel feedback has been incorporated, with the
   focus being that the document is defining an ESP profile for
   resource-constrained devices.

Document Quality

   Nothing of note.  Thanks to all the Last Call feedback and directorate
   reviews received so far.

Personnel

   Mohit Sethi is the document Shepherd.
   Erik Kline is the responsible Area Director.
