Cryptography, secret writing, is enjoying a scientific renaissance following the seminal
discovery in 1977 of public-key cryptography and applications in computers and …

There have existed several “card-based protocols” for secure computations of a Boolean
function such as AND and XOR. The best result currently known is that AND and XOR can …

Secure multiparty computation can be done with a deck of playing cards. For example, den
Boer (EUROCRYPT'89) devised his famous “five-card trick”, which is a secure two-party …

We propose a technique to construct physical Zero-Knowledge Proof (ZKP) protocols for
puzzles that require a single loop draw feature. Our approach is based on the observation …

By using a deck of cards, it is possible to realize a secure multiparty computation. In
particular, since a new shuffling operation, called a random bisection cut, was devised in …

This paper proposes new card-based cryptographic protocols to calculate logic functions
with the minimum number of cards using private operations under the semi-honest model …

The “five-card trick” invented by Boer allows Alice and Bob to securely compute the AND
function of their secret inputs using five cards—three black cards and two red cards—with …

Consider a face-down card lying on the table such that we do not know whether its suit color
is black or red. Then, how do we make identical copies of the card while kee** its color …

Consider the holiday season, where there are n players who would like to exchange gifts.
That is, we would like to generate a random permutation having no fixed point. It is known …

Makaro is a logic game similar to Sudoku. In Makaro, a grid has to be filled with numbers
such that: given areas contain all the numbers up to the number of cells in the area, no …
