Hello,
I think GNUnet is a very valuable effort in "fixing" the internet and
I would like to thank everyone involved with it.
I really enjoyed reading the CADET paper and I'm not sure if GNUnet is
a direct implementation of CADET, but here are some thoughts about
CADET that I would like to throw in for discussion. Please do tell me
if I'm wrong.
I understand that there's link encryption between participants to
maintain message integrity and anonymity on the basic layer. Then
there's end-to-end encryption and connection redundancy (leaving aside
the multiplexing layer for now).
However, it seems to me a relaying node can still intercept a fair
amount of meta data through path information that's being sent along
with messages. I understand that this is intentional since the
protocol is designed for restricted route scenarios and nodes are able
to learn the network topology very quickly this way, but I believe
that using these connectivity paths for direct (albeit encrypted)
communication is a privacy flaw and invites censorship, because any
relaying node can learn who you're communicating with.
What I've been thinking about is the role a mix network layer
reminiscent of Tor could play in GNUnet.
What do you think?
cheers,
Marcel
