> I would like to see security on that list. What do you want that isn't already covered by NTS and/or shared keys? (I think we need to move the MAC for shared keys into an extension. That's not a "big picture" item.) ------- As far as I can tell, the problem with NTP security is deployment of NTS. The pool has captured a large portion of the market and it is fundamentally insecure. HTTPs works because lots of sites want your money. Nobody is paying for NTP. I see two ways to get a wide deployment. One is to get ISPs to run secure NTP servers for their clients. The other is to deploy something similar to the DNS root and top level servers. I don't know how that works, in particular, who pays for it. -- These are my opinions. I hate spam.
