tini2p 0: Greetings
hello all
1: What's been done
merged ECIES updates for 144 updates + my spec suggestions: tini2p/tini2p!12
had a long discussion about 144 at this week's LS2 meeting: tini2p/meta#23
getting closer to a solid spec there, though there is still quite a bit to get done / come to consensus on
more updates to 152, and got rid of Blowfish: https://gitlab.com/snippets/1878282
tini2p basically, instead of using Blowfish for nonce encryption, tunnel gateways will keep a nonce counter
they advance the counter for every set of tunnel messages, concatenate the counter to the random tunnelNonce, and participants use the counter to ChaCha20 encrypt the tunnelNonce
participants don't change the counter value, but do need to verify it against an independent Bloom filter
there may be a fancy way to validate uniqueness of the counter without a separate Bloom filter, or save space by having a sliding Bloom filter with fewer elements that advances as it becomes full, TBD
the naive way is just to have two Bloom filters though: one for the tunnelNonces, one for the counters
tini2p unfortunately had to spend more time than I wanted working on specs this last week, so didn't make as much progress on code as I wanted
began work on ECIES tunnels, and have the BuildRequestRecord and BuildReplyRecord basically done: https://gitlab.com/tini2p/tini2p/tree/tunnels
2: What's next
I'll be spending the remainder of today working on tunnels, trying to get them "finished" (aka functional)
if I can't get them done today, I'll push back alpha release one more week. will do all I can to complete the work on end-to-end communication through tunnels
I could just "ship it" today, but tunnels aren't complete. I would really like to have an end-to-end functional setup in alpha release, even without interop with existing I2P network
tini2p even with interop, I will be setting a testnet netid, so communication with the main I2P network would require custom compilation
so, my focus will be on getting ECIES tunnels working with ECIES-only tunnels, and using the new layer encryption proposed in 152
hopefully, that will be finished by next week
after that, I will implement mixed tunnels with ElGamal participants, and the existing tunnel layer encryption
3: Questions / comments
tini2p 4: Next meeting time
2019-08-08 18:00 UTC
if I'm able to make alpha release by next Thurday, I'll make an announcement in here as well.
no meeting next week otherwise
David Burkett :thumbsup: Keep up the good work @tini2p_gitlab
tini2p thanks @DavidBurkett :smile:
David Burkett If you ever need me to help test anything, I'll gladly do so. Just let me know.
tini2p will do, thanks for the offer!!
thanks to all for attending / reading
