Abstract:
The Network Time Protocol Version 4 (NTPv4) defines in RFC5905 the
optional usage of Message Authentication Code (MAC). The MAC is an
optional component of the NTP packet at the end of the packet. There
can only be one MAC segment in the packet but there is no way of
knowing if the last data segment at the end of an NTP packet is a MAC
or an extension field, which is also defined in RFC5905. This draft
defines a MAC extension field which will allow the existing MAC
segment to be moved into an extension field and have a known length
and deprecates the existing MAC.
