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 the Subject line to allow automated sorting. 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ntp-mac/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-ntp-mac/ballot/ No IPR declarations have been submitted directly on this I-D.
