Christian Schindelhauer describes sophisticated protocols to both perform and verify a large number of useful operations on cards and stacks of cards in his 1998 paper [SCH98]. The work is concerned with general-purpose operations (masking and unmasking cards, shuffling and re-shuffling, inserting a card into a stack, etc.) that make the protocols applicable to any card game.

LibTMCG is an A C ++ library for creating secure and fair online card games.
Other question that it hardly solves task ...

the Casino shuffles a pack, ciphers the general key and passes round.
The next participant shuffles a pack, ciphers the general key and passes round further.
The casino receives again receives a pack, decrypts it (removes the general key) and ciphers each card individual keys.
The casino ciphers a pack the second general key and passes round.

What for the second time to cipher all pack? Removing the general enciphering of a casino all the same cannot learn a card any more because at present they are already ciphered by players. In the same way it cannot make and players since when the last general key will be removed - on each card there will be already a complete set individual.
I estimated Shamir's code (with small keys) - like approaches, at observance of one condition: to be decrypted cards should in the same order in which were ciphered.
