On behalf of the VIFF Development Team, I am very happy to announce the release of VIFF 0.5:
Tar/GZ: http://viff.dk/release/viff-0.5.tar.gz Tar/BZ2: http://viff.dk/release/viff-0.5.tar.bz2 Zip: http://viff.dk/release/viff-0.5.zip Exe: http://viff.dk/release/viff-0.5.win32.exe Changes since version 0.4: Added preliminary support for preprocessing and an efficient multiplication protocol which is secure against active adversaries. The Runtime class has been split into several parts and two new mixin classes provide different comparison protocols. Several coercion problems were fixed. The Runtime.callback method was renamed to Runtime.schedule_callback. VIFF was tested on Python 2.6 and some small problems were fixed. If python-gnutls is unavailable, players now automatically fallback to TCP connections. The installation guide was updated for Windows Vista. A new example program was added and the documentation was updated. Changed license to LGPL. About VIFF: Virtual Ideal Functionality Framework is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multi-Party Computation) to Python.
