Practical Card-Based Protocol for Three-Input Majority

Kenji Yasunaga

Abstract

We present a card-based protocol for computing a three-input majority using six cards. The protocol essentially consists of performing a simple XOR protocol two times. Compared to the existing protocols, our protocol does not require private operations other than choosing cards.
