| Summary: C++ library for creating secure and fair online card games | |
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.

- Update to version 1.3.15
This is a maintenance release that fixes some bugs, e.g. in the Botan
support of functions from module mpz_srandom. Moreover, some interfaces
of the OpenPGP implemenation have been added and removed. For some
modules of LibTMCG a basic exception handling has been introduced.

With this release three additional parameters for the control of secure
memory allocation have been added to init_libTMCG(). They are explained
in the reference manual. Moreover, the OpenPGP interface has been
enhanced in several way, e.g., ECDH, ECDSA and EdDSA are supported now.
