Homomorphic encryption, secure multi-party computation, and differential privacy are part of
an emerging class of Privacy Enhancing Technologies which share a common promise: to …

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 …

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 …

The elegant “five-card trick” of den Boer (EUROCRYPT 1989) allows two players to securely
compute a logical AND of two private bits, using five playing cards of symbols ♡ and ♣ …

Card-based protocols enable us to easily perform cryptographic tasks such as secure
multiparty computation using a deck of physical cards. Since the first card-based protocol …

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 …

Starting from the five-card trick proposed by Den Boer (EUROCRYPT'89), many card-based
protocols performing secure multiparty computations with a deck of physical cards have …
