Hello,
This is Kyung Hwang from Columbia University again. I have another question.
Does Viff always need at least 3 participants? It seems to me it does.
I modified beginner.py for two players because that file was
simplest to modify, but when I ran the two players, I got the
following errors:

That depends on the runtime you use. If you are using the default

It is not good to use the wrong kind of PRG, it should
be fixed as soon as possible. But do we know that
os.urandom will be OK on any platform, or is this
OS -dependent at the end of the day?

Indeed it should satisfy those properties. Say if you Shamir share
something, the adversary might get t shares in order. If it can guess
the next bit with non-negligible advantage, this will completely break
our claim that the adversary has no information on the secret.
Luckily it should

I agree that tests should be reproducible. But it is also very
important to use a cryptographically secure PRNG.
I don't know whether these two requirements can be satisfied by the
same number generator. If not, the best solution is to have two
modes of operation:

Hi everybody!
On behalf of the VIFF Development Team, it is my pleasure to declare
that we have reached VIFF version 1.0. The current code is useful,
flexible and unlikely to change radically. Please download it here:

Hi everybody,
I would like to release what we currently have in VIFF as version 1.0
this weekend. The code has not evolved very much the last year, and
releasing version 1.0 now will fit nicely with the reports we're writing
for CACE and with my own dissertation :-)
As preparation for that, I've

Hi,
I hope this question is not a bother to you.
No, not at all
I was trying to test viff-0.7.1, as I executed generate-config-files.py, I
got the error ¨ImportError: No module named viff.config¨. Im not sure how to
fix this problem.
Most likely viff is not yet on your PYTHONPATH

Hi Thomas
I've written a VIFF application that should make it easy to create,
run and visualize benchmarks for VIFF protocols.
I've put some changes to it here -- it's only style changes in order to
make it more pythonic :-) Please pull from this
