Re: [freenet-chat] questions about freenet/i2p/entropy</i><br>Date: <i>Thu,

document storage and retrieval,<br>>whereas I2P has focussed on real time
connections between nodes. That's<br>>the obvious difference. I2P
implements a form of onion routing to<br>>protect these connections; in
I2P, you construct a 3 hop tunnel from<br>>your node to somewhere, using
nodes from all over the network. Whereas<br>>freenet's routing is more
heuristic, often taking 7 or more hops, and<br>>exclusively uses the
routing table, pre-established connections,<br>>although it is important
for new connections to be established from time<br>>to time. Both
approaches have advantages, in both security and<br>>performance; they
are complementary, for the time being.<br>><br>>In terms of security,
I2P and Freenet are completely different; I2P is a<br>>scalable mixnet,
which is inherently harvestable, meaning that an<br>>attacker can quickly
find all nodes, but in which it should be very hard<br>>to find the
originator of a connection (this is however a topic of
some<br>>dispute!). For Freenet to have really good anonymity, we will
have to<br>>add a layer of "premix routing", meaning onion
routing, a la I2P, but<br>>probably over our existing connections; this
does not mean that<br>>Freenet's anonymity right now is rubbish, but
various attacks are<br>>possible which we would like to prevent. It has
been suggested to use<br>>I2P to do this, but there are some major
problems with that for example<br>>harvestability. Freenet's anonymity
as-is is probably worse than I2P's,<br>>but Freenet is known to scale in
practice to at least 10,000 nodes,<br>>whereas I2P has maybe 300. Freenet
0.7 will have a scalable darknet F2F<br>>option, where each node only
connects to those which are explicitly added<br>>as belonging to friends
of the node operator; this can scale, because<br>>although I only connect
to my friends, they connect to theirs, and you<br>>can span the globe
pretty fast. The upshot of this is that it is not<br>>harvestable any
more, and a whole variety of attacks become much harder<br>>and much less
useful. This is intended for use in hostile environments,<br>>such as
China, Saudi Arabia, and Iran, where the internet is
heavily<br>>filtered. China does not yet do harvesting of Freenet or I2P
nodes, but<br>>it does block Freenet by other means (which rely on a
misfeature which<br>>will also be eliminated in
0.7).<br>><br>>Entropy, as far as I know, was a rip-off of Freenet. It
even used FCP.<br>>:) It had more or less the same goals, but used
home-grown crypto<br>>algorithms (which is *ALWAYS* a bad thing), and had
a primitive routing<br>>algorithm which suggests it probably wouldn't
have scaled.<br>><br>>On Mon, Oct 31, 2005 at 08:20:41PM -0800, none
