%description -n libTMCG%{sover}
LibTMCG is a C++ library for creating secure and fair online card
games. The library contains classes, algorithms, and high-level
protocols to support an application programmer in writing such
software. Neither a trusted third party (TTP), i.e. a central game
server, nor trusted hardware components are necessary. With the
library, there is no need for an independent referee, because the
applied protocols provide a basic level of confidentiality and
fairness by itself. The library is suited for peer-to-peer (P2P)
environments where no TTP is available.

It cannot be avoided that malicious players share information about
their private cards, but the protocols ensure that the shuffle of the
deck is performed randomly (presumed that at least one player is
honest) and thus the cards will be distributed uniformly among the
players. Further, no coalition can learn the private cards of a
player against his will (except for trivial conclusions). The
corresponding cryptographic problemis called Mental Poker, and
LibTMCG provides an implementation of such protocols.

The implementation relies on cryptographic techniques---the so-called
zero-knowledge proofs. Using these building blocks, the high-level
protocols minimize the effect of coalitions and preserve the
confidentiality of the players' strategy, i.e. the players are not
required to reveal their cards at the end of the game to show that
they did not cheat.
