[viff-devel] Multiparty AES in less than 3 seconds per block thanks to Twisted hack

Hi Ivan,

I call it a hack because of two reasons:
- The maintainer of Twisted doesn't want to implement something similar 
upstream.
- It breaks some unit tests. I'm not sure whether it really breaks 
functionality or just the unit testing tool of Twisted.

As I said at the meeting, a possibility would be to go multi-threaded. 
The Twisted maintainer suggested another way but I don't think that that 
way works for us. If we manage to solve the problem with the unit tests, 
we could of course somehow modify the relevant part of Twisted from 
within VIFF.

Best regards,
Marcel
