Suguru is a paper and pencil puzzle invented by Naoki Inaba. The goal of the game is to fill
a grid with numbers between 1 and 5 while respecting three simple constraints. We first …

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 …

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 …

This paper shows new card-based cryptographic protocols using private operations that are
secure against malicious players. Physical cards are used in card-based cryptographic …

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, a commitment to a Boolean value is usually represented by two
face-down cards of different colors or numbers, whose order specifies the one-bit value …

Consider a group of people who want to know the “rich list” among them, namely the ranking
in terms of their total assets, without revealing any information about the actual value of their …

Card-based cryptography is an area involving cryptographic techniques that use a deck of
physical cards to implement secure computation. In this paper, we study card-based …

Card-based cryptography typically uses a physical deck comprising black and red cards to
perform secure computations, where a one-bit value is encoded using a pair of cards with …
