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.
