LibTMCG is a C++ library for creating secure and fair online card games. The
|
|
library provides a sort of useful classes, algorithms, and high-level protocols
|
|
to support an application programmer in writing such software. The most
|
|
remarkable feature is the absence of a trusted third party (TTP), i.e. neither a
|
|
central game server nor trusted hardware components are necessary. Thus, with
|
|
the present library there is no need for an independent referee, because the
|
|
applied protocols provide a basic level of confidentiality and fairness by
|
|
itself. Consequently, the library is well-suited for peer-to-peer (P2P)
|
|
environments where no TTP is available. Of course, we cannot avoid 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 problem, actually called Mental Poker, has been studied since 1979
|
|
(Shamir, Rivest, and Adleman) by many authors. LibTMCG provides the first
|
|
practical implementation of such protocols.
