Cryptography without computers - computations with a deck of cards

Description	We discuss sophisticated card-based protocols for secure computations with a deck of cards, i.e. cryptography without computers. However, we show also the possibility to implement these protocols with LibTMCG - the C++ library for creating secure and fair online card games.

We discuss sophisticated card-based protocols for secure computations with a deck of cards, i.e. cryptography without computers. However, we show also the possibility to implement these protocols with LibTMCG - the C++ library for creating secure and fair online card games.

In particular we will discuss the following papers:

• Takaaki Mizuki and Hideaki Sone: Six-Card Secure AND and Four-Card Secure XOR, LNCS 5598, 2009.
• Takaaki Mizuki and Hiroki Shizuya: Practical Card-based Cryptography, LNCS 8496, 2014.
