SecureSkat - Summary

This group is not part of the GNU Project.

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). It uses the C++ library LibTMCG to ensure a reasonable level of verifiability for the card operations (e.g. shuffling). Furthermore, SecureSkat provides electronic voting capabilities based on a simple playing card encoding.

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. In general, 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. Moreover, face-down or private cards can be opened only, if all players work together.
