I'm very happy to announce the release of VIFF version 0.4: Tar/GZ: http://viff.dk/release/viff-0.4.tar.gz Tar/BZ2: http://viff.dk/release/viff-0.4.tar.bz2 Zip: http://viff.dk/release/viff-0.4.zip Exe: http://viff.dk/release/viff-0.4.win32.exe The changes since version 0.3 are: Implemented a reliable Bracha broadcast which is secure against active adversaries. Shamir sharings, pseudo-random as well as standard, can now be asymmetric which means that only a subset of the parties provide input. The open protocol is now also asymmetric, in the sense that only a subset of the parties receive the opened result. The behavior of field elements in Boolean expressions has been fixed. This means that "GF256(0) and GF256(1)" now returns GF256(0) instead of GF256(1). Added a modern implementation of the classic Yao millionaires example from 1982 which started this field of research. 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.
