Card-based Cryptography with Dihedral Symmetry [PDF]
New Generation Computing, 2021 AbstractIt is known that secure computation can be done by using a deck of physical cards. This area is called card-based cryptography. Shinagawa et al. (in: Provable security—9th international conference, ProvSec 2015, Kanazawa, Japan, 2015) proposed regular n-sided polygon cards that enable to compute functions over $${\mathbb {Z}}/n{\mathbb {Z}}$$

Cyclic Equalizability of Words and Its Application to Card-Based Cryptography
Lecture Notes in Computer ScienceCard-based cryptography is a research area to implement cryptographic procedures using a deck of physical cards. In recent years, it has been found to be related to finite group theory and algebraic combinatorics, and is becoming more and more closely connected to the field of mathematics.

New Generation ComputingAbstractCard-based cryptography is a secure computation protocol realized by using physical cards. There are two models on card-based cryptography: public and private models. We adopt private one that allows players to handle cards privately. While much of the existing works for card-based cryptography use two-colored cards, it is also a vital task to ...

Efficient and anonymous two-factor user authentication in wireless sensor networks: achieving user anonymity with lightweight sensor computation. [PDF]
PLoS ONE, 2015 A smart-card-based user authentication scheme for wireless sensor networks (hereafter referred to as a SCA-WSN scheme) is designed to ensure that only users who possess both a smart card and the corresponding password are allowed to gain access to sensor

Card-Based Cryptography Meets Formal Verification [PDF]
New Generation Computing, 2019 AbstractCard-based cryptography provides simple and practicable protocols for performing secure multi-party computation with just a deck of cards. For the sake of simplicity, this is often done using cards with only two symbols, e.g., $$\clubsuit $$ ♣ and $$\heartsuit $$ ♡ .

Secure Electronic Payment Methods for Online Shopping Based on Visual Cryptography
Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi), 2020 Phishing and identity theft are common threats of online shopping. Phishing is an attempt to steal personal data from legitimate user. In this paper we propose a secure e-payment method using a credit card based on visual cryptography. This method adopts
