Card-Based Computation in the Virtual Player Simulation Model
[Kryptografia i bezpieczeństwo] Autorzy: Suthee Ruangwises
Player simulation has recently emerged as a new direction in card-based cryptography, with protocols developed for simulating virtual players in physical card games such as Old Maid, UNO, and President. Unlike conventional card-based secure computation, player simulation imposes additional constraints: the cards represent a persistent game state, the remaining cards in a virtual player's hand must be preserved after each action, and it is desirable to represent each card in the game by a single physical card. In this paper, we study generic card-based computation in the virtual player simulation model. We focus on games whose cards admit a publicly known ranking and propose two fundamental protocols. First, we present the Play-Minimum protocol, which securely selects and plays the minimum-value card from a virtual player's hand when all cards in the deck have distinct values. By symmetr…
