Virtual Ideal Functionality Framework 0.4 (Default branch)
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. License: GNU General Public License (GPL) Changes:
This release implements a reliable Bracha broadcast that is secure against active adversaries. Sharings 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). A modern implementation of the classic Yao millionaires example from 1982, which started this field of research, has been added.Image

MAC_TEST(4)						   BSD Kernel Interfaces Manual 					       MAC_TEST(4)

NAME

     mac_test -- MAC framework testing policy

SYNOPSIS

     To compile the testing policy into your kernel, place the following lines in your kernel configuration file:

	   options MAC
	   options MAC_TEST

     Alternately, to load the testing module at boot time, place the following line in your kernel configuration file:

	   options MAC

     and in loader.conf(5):

	   mac_test_load="YES"

DESCRIPTION

     The mac_test policy module implements a testing facility for the MAC framework.  Among other things, mac_test will try to catch corrupt
     labels the system is attempting to destroy and drop to the debugger.  Additionally, a set of statistics regarding the number of times various
     MAC framework entry points have been called is stored in the security.mac.test sysctl(8) tree.

   Label Format
     No labels are defined for mac_test.

     mac_seeotheruids(4), mac(9)

HISTORY

     The mac_test policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.

AUTHORS

     This software was contributed to the FreeBSD Project by Network Associates Labs, the Security Research Division of Network Associates Inc.
     under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.

BUGS

     See mac(9) concerning appropriateness for production use.	The TrustedBSD MAC Framework is considered experimental in FreeBSD.

     While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by
     entry point checks.  As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user.
