Re: [Ntp] draft-schiff-ntp-chronos-03

Hi,

I am not sure why the link to the paper doesn't work, I'll fix it in the
next draft.
However, the proper link is:
https://www.ndss-symposium.org/wp-content/uploads/2018/02/ndss2018_02A-2_Deutsch_paper.pdf

Regarding the "w" parameter:
- It denotes an upper bound on the distance from the UTC of the local time
at any NTP server with an accurate clock (“truechimer”).
- We analyzed "w" value empirically in section 5.B, and set it to 25 ms,
such that over 83% of the servers (on average) are considered honest
servers.
- This value also used for the security analysis in section 4.B.

Best,
Neta
