Atm CPU is the bottleneck as Tor routers can't keep up with path lookups crypto. Padding messages to consume more unused bandwidth to make netflow correlation attacks more difficult makes sense. Seth David Schoen wrote: > Has anybody looked at the new HORNET system? > > http://arxiv.org/abs/1507.

I have not but I'm happy to read the article. Is there a discussion group for onion router and mixnet design? tor-talk might be a big generic for this. On Wed, Jul 22, 2015 at 11:36 PM, Seth David Schoen wrote: > Has anybody looked at the new HORNET system? > > http://arxiv.org/abs/1507.05724v

2015-07-22 Thread Seth David Schoen
Has anybody looked at the new HORNET system? http://arxiv.org/abs/1507.05724v1 It's a new onion routing design that seems to call for participation by clients, servers, and network-layer routers; in exchange it claims extremely good performance and scalability results. I think it also calls for
