Card-Based Computation in the Virtual Player Simulation Model
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 Mai…
Cyclic Equalizability Characterized by Parikh Vectors
Sarunyu Thongjarast, Sarit Pasiphol, Suthee Ruangwises
Cyclic equalizability is a notion introduced by Shinagawa and Nuida in 2025, in the study of card-based cryptography. Informally, a collection of words is cyclically equalizable if…
A Complexity Hierarchy of Shuffles in Card-Based Protocols
Tomoki Ono, Suthee Ruangwises
Card-based cryptography uses physical playing cards to construct protocols for secure multi-party computation. Existing card-based protocols employ various types of shuffles, some…
Wataridori is NP-Complete
Suthee Ruangwises
Wataridori is a pencil puzzle that involves drawing paths in a rectangular grid to connect circles into pairs while satisfying several constraints. In this paper, we prove that dec…
