The IESG has received a request from the Network Time Protocol WG (ntp) to
consider the following document: - 'Message Authentication Code for the
Network Time Protocol'
  <draft-ietf-ntp-mac-05.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2018-10-19. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the beginning of

Abstract


   RFC 5905 [RFC5905] states that Network Time Protocol (NTP) packets
   should be authenticated by appending a 128-bit key to the NTP data,
   and hashing the result with MD5 to obtain a 128-bit tag.  This
   document deprecates MD5-based authentication, which is considered to
   be too weak, and recommends the use of AES-CMAC [RFC4493] as a
   replacement.
