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 …

Yao's millionaire protocol enables Alice and Bob to know whether or not Bob is richer than
Alice by using a public-key cryptosystem without revealing the actual amounts of their …

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 …

Card-based cryptography, as first proposed by den Boer (EUROCRYPT 1989), enables
secure multiparty computation using only a deck of playing cards. Many protocols as of yet …

Card-based cryptography, introduced by den Boer aims to realize multiparty computation
(MPC) by using physical cards. We propose several efficient card-based protocols for the …

Sumplete is a logic puzzle generated by ChatGPT in March 2023. The puzzle consists of a
rectangular grid, with each cell containing an integer. Each row and column also has an …

Card-based cryptography is a variant of multi-party computation using physical cards like
playing cards. There are two models on card-based cryptography, called public and private …

In card-based cryptography, designing AND protocols in committed format is a major
research topic. The state-of-the-art AND protocol proposed by Koch, Walzer, and Härtel in …

This paper proposes new efficient card-based cryptographic protocols for the millionaires'
problem using private input operations. The millionaires' problem is one of the fundamental …
