Folks,

We have posted a new revision of the ntp port randomization I-D. It
contains a number of improvements based on the recent discussion, along
with an analysis of a number of considerations surrounding port
randomization.

It is available at:
https://www.ietf.org/internet-drafts/draft-gont-ntp-port-randomization-02.txt

We don't expect this rev to be perfect, but do we think this one is
ready for the wg to make a decision regarding whether to adopt this
document as a wg item.

P.S.: If there's anything you think we have missed, please do let us know.

Thanks!

Cheers,
Fernando

Abstract:
   The Network Time Protocol can operate in several modes.  Some of
   these modes are based on the receipt of unsolicited packets, and
   therefore require the use of a service/well-known port as the local
   port number.  However, in the case of NTP modes where the use of a
   service/well-known port is not required, employing such well-known/
   service port unnecessarily increases the ability of attackers to
   perform blind/off-path attacks.  This document formally updates
   RFC5905, recommending the use of port randomization for those modes
   where use of the NTP service port is not required.




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.
