Fair online gambling scheme and TTP-free mental poker protocols

Abstract

Online gambling allows users to participate in mental games and bet over the Internet. It can open new opportunities for casinos to make more money; however, at the same time, there are a lot of security challenges. In this paper, we describe our scheme for secure online gambling and secure mental poker protocols over the Internet based on our previous researches. Our scheme provides both the fairness of online gambling processes and secure linking of the online gambling with payment. A unique link between payments and gambling outcome is provided so that the winner can be ensured to get the payment. The gambling games are generic in our fair online gambling scheme. Mental poker is one of most popular games of online gambling. In this paper, efficient and secure mental poker protocols are provided. These mental poker protocols are based on multiple encryption and decryption of individual cards. These protocols satisfy all major security requirements of a real mental poker. The card salesman has been got rid of and the minimal effect due to collusion has been guaranteed. These protocols are more efficient compared with other known protocols. The strategies of players can be kept confidential with the introduction of a dealer. These mental poker protocols are suitable for implementation in an online card game.

A secure mental poker protocol over the Internet

Weiliang Zhao, Weiliang Zhao, Vijay Varadharajan +1 more

An efficient and secure mental poker scheme is proposed in this paper. It is based on multiple encryption and decryption of individual cards. The protocol satisfies all major security requirements of a real mental poker. It gets rid of the Card Salesman and guarantees minimal effect due to collusion of players. The protocol is secure and more efficient compared with other known protocols. The strategies of players can be kept confidential with the introduction of a Dealer. The protocol is suitable to be implemented in an on-line card game.

Mental poker protocol without trusted third party

Haiyan Xiao

Mental poker is a secure multi-party computation solution in specific scene.In recent years,the studies on mental poker protocol in academe are mainly based on Trusted Third Party(TTP).Using the semantic secure encrypt algorithm,combining with the signature algorithm in which the two signatures become effective at the same time,a mental poker protocol without TTP in an unreliable channel was designed.The new protocol can ensure the fairness of game participators and resist the attack of playback,with the advantages of non-repudiation,unforgeability and traceability.

Efficient Electronic Gambling: An Extended Implementation of the Toolbox for Mental Card Games.

Heiko Stamer

Abstract: There are many wonderful protocols in cryptography which are still waiting for their realization. Here we consider efficient solutions for secure electronic card games. Our contribution seems to be the first known practical implementation that requires no trusted third-party and simultaneously keeps the players ’ strategies confidential. The provided open source library LibTMCG can be used for creating secure peer-to-peer games and furthermore for some unusual applications, e.g., secure multiparty computation or simple electronic voting schemes.

Efficient TTP-free mental poker protocols

Weiliang Zhao, Vijay Varadharajan

Zhao et al proposed an efficient mental poker protocol which did not require using a trusted third party (TTP). The protocol is efficient and suitable for any number of players but it introduces a security flaw. In this paper, we propose two mental poker protocols based on Zhao's previous work. The security flaw has been removed and the additional computing cost is small.

A Toolbox for Mental Card Games

Christian Schindelhauer

Mental card games are played without a trusted party and without cards. It is well known that the problem of mental card games can be solved in principle. But the schemes known so far are too messy to be used in practice. Only for the mental poker game a suitable solution is known [Cr'ep 87] that achieves security against player coalition and complete confidentiality of a player's strategy. Here, we present a general-purpose scheme that may be used as basic toolbox for straight-forward implementations of card games. We present a data structure for cards and decks that is secure against player coalitions and enables standard operations like picking up a card, opening it, and (re-)mixing stacks. Futhermore, we introduce tools for special operations like inserting a card into the deck, splitting the deck, parting the game. The correctness of all operations is testified by zeroknowledge proofs. Finally, we discuss security problems that are typical for mental card games and suggest solutio...

Security protocol for P2P card games

Jia Cao

Unlike real world and C/S model,it is difficult for P2P games to guarantee security and fairness because it lacks of a Trusted Third-party(TTP).In this paper,a secure scheme for P2P poker games is proposed,which is based on common operations,such as permutation and symmetric cryptography.The logic security analysis manifests that it is secure and fair.On the other hand,the communication costs of the scheme is low so that it can be used to wireless hand-hold devices.
