Card-based Cryptography Meets Formal Verification
secure multiparty computation card-based cryptography formal verification
2019/9/17
Card-based cryptography provides simple and practicable protocols for performing secure multi-party computation (MPC) with just a deck of cards. For the sake of simplicity, this is often done using ca...
A Single Shuffle Is Enough for Secure Card-Based Computation of Any Circuit
Card-based protocols Secure computations Garbled circuits
2019/4/16
It is known that information-theoretically secure computation can be done by using a deck of physical cards. In card-based protocols, shuffles, which covertly rearrange the order of cards according to...
Memory-Constrained Implementation of Lattice-based Encryption Scheme on the Standard Java Card Platform
Post-Quantum Cryptography Lattice-based Encryption Scheme Java Card
2019/1/2
Memory-constrained devices, including widely used smart cards, require resisting attacks by the quantum computers. Lattice-based encryption scheme possesses high efficiency and reliability which could...
In the area of card-based cryptography one devises small and easy to perform protocols for secure multiparty computation using a deck of physical playing cards with indistinguishable backs, which can ...
Is Java Card ready for hash-based signatures?
Post-quantum cryptography hash-based signatures Java Card
2018/6/25
The current Java Card platform does not seem to allow for fast implementations of hash-based signature schemes. While the underlying implementation of the cryptographic primitives provided by the API ...
21 - Bringing Down the Complexity: Fast Composable Protocols for Card Games Without Secret State
Multiparty Computation Card Games Cryptographic Protocols
2018/4/4
While many cryptographic protocols for card games have been proposed, all of them focus on card games where players have some state that must be kept secret from each other, e.g. closed cards and bluf...
ROYALE: A Framework for Universally Composable Card Games with Financial Rewards and Penalties Enforcement
Poker Card Games Fairness Blockchain
2018/3/7
While many tailor made card game protocols are known, the vast majority of those suffer from three main issues: lack of mechanisms for distributing financial rewards and punishing cheaters, lack of co...
Using the Estonian Electronic Identity Card for Authentication to a Machine (Extended Version)
smart cards implementation
2017/9/18
The electronic chip of the Estonian ID card is widely used in Estonia to identify the cardholder to a machine. For example, the electronic ID card can be used to obtain benefits in customer loyalty pr...
The Minimum Number of Cards in Practical Card-based Protocols
Card-based protocols Committed format Boolean AND
2017/9/13
Koch, Walzer and Härtel (ASIACRYPT 2015) showed that five cards suffice for computing AND in finite runtime, albeit using relatively complex and unpractical shuffle operations. In this paper, we ...
