SecureSkat is a peer-to-peer implementation of the German card game Skat. The program negotiates possible players and game sessions over an arbitrary IRC network (Internet Relay Chat). Further it employs LibTMCG to gain a reasonable level of fairness.

The cryptographic protocols of SecureSkat are designed with respect to the 'honest-but-curious' (aka semi-honest) adversary model. Thus we don't care about robustness or strong availability which are hard to achieve in a asynchronous environment. The success of a cheating player can be bound by the security parameter t such that the soundness error probability (w.r.t. performed card operations) is less or equal than 2^{-t}. However, we cannot prevent that malicious players share information about their private cards. But the protocols ensure that the shuffling of the deck is performed randomly (provided that at least one player is honest) and hence that the cards are distributed uniformly among the players.

This is a code cleanup and bugfix release. First, some namespace issues have been solved in order to compile with newer versions of GCC and stdc++. Additionally, a bug in the rank statistic command has been fixed which was introduced in the previous version 2.8. Finally, the obsolete GnuTLS dependency has been removed.

Toni Graffy (PackMan team) has kindly provided RPM packages for SuSE Linux 10.0, 10.1, and openSuSE 10.2. The packages are available on
http://packman.links2linux.de/package/SecureSkat/ and in the PackMan repository as well.

SecureSkat 2.8 released
     posted by stamer, Thu 10 May 2007 06:22:00 AM UTC - 0 replies

The cryptographic key generation has been improved and some obsolete functions removed. Furthermore, a massive code cleanup has been performed.

SecureSkat 2.7 released
     posted by stamer, Thu 13 Apr 2006 06:22:22 AM UTC - 0 replies

The focus of this release are major feature enhancements in LibTMCG which improve the performance and communication complexity of SecureSkat significantly. Unfortunately, because of this change it is not possible to establish game sessions with versions prior to 2.7. Further, key fingerprints are now showed by the command /players and Null-games are aborted immediately, if they are lost by the playing party.
