A critique of game-based definitions of receipt-freeness for voting
E-voting receipt-freeness privacy
font style='font-size:12px;'>
2019/7/24
We analyse three game-based definitions of receipt-freeness; uncovering soundness issues with two of the definitions and completeness issues with all three. Hence, two of the definitions are too weak,...
Quantum Lazy Sampling and Game-Playing Proofs for Quantum Indifferentiability
game-playing proofs QROM indifferentiability
font style='font-size:12px;'>
2019/4/28
Game-playing proofs constitute a powerful framework for classical cryptographic security arguments, most notably applied in the context of indifferentiability. An essential ingredient in such proofs i...

2019/4/15
Trick-Taking Games (TTGs) are card games in which each player plays one of his cards in turn according to a given rule. The player with the highest card then wins the trick, i.e., he gets all the card...
Game Channels: State Channels for the Gambling Industry with Built-In PRNG
blockchain distributed cryptography public-key cryptography

2019/4/10
Blockchain technology has immense potential. At the same time, it is not always possible to scale blockchains. State Channels solve the problem of scalability while increasing the blockchain's speed a...
Game Theoretic Notions of Fairness in Multi-Party Coin Toss
coin toss coin flip
font style='font-size:12px;'>
2018/11/12
Coin toss has been extensively studied in the cryptography literature, and the well-accepted notion of fairness (henceforth called strong fairness) requires that a corrupt coalition cannot cause non-n...
Simplifying Game-Based Definitions: Indistinguishability up to Correctness and Its Application to Stateful AE
indistinguishability oracle silencing provable security
font style='font-size:12px;'>
2018/6/5
Often the simplest way of specifying game-based cryptographic definitions is apparently barred because the adversary would have some trivial win. Disallowing or invalidating these wins can lead to com...
CryptHOL: Game-based Proofs in Higher-order Logic
Provable Security Game-based Proofs Theorem Proving
font style='font-size:12px;'>
2017/8/8
Game-based proofs are a well-established paradigm for structuring security arguments and simplifying their understanding. We present a novel framework, CryptHOL, for rigorous game-based proofs that is...
Game-Theoretic Security for Two-Party Protocols

font style='font-size:12px;'>
2015/12/22
In this paper, we consider the following question: Does composing protocols having gametheoretic
security result in a secure protocol in the sense of game-theoretic security? In order
