Abstract

Along with the Internet universal,the safe problem of network also increasingly important,we need a kind of legal means urgently to guarantee the communications' safety,protocol appear under this kind of background.Start from self-enforcing protocol that in the code protocol,intelligence poker game based on a fair coin toss protocol hare studied,it was RSA key system that employed in the agreement.The fairness of random number generator communication employed has got the further assurance in the procedure.

Fair Coin Toss Protocol Based on Composite Degree Residue Classes

LI Ji-lian

In real life,tend to encounter many difficult choices. At this time,tend to solve the coin toss. It becomes difficult to play the game that needs face-to-face mechanism to ensure the fairness on Internet at the network information age,so playing coin toss game on Internet has valuable significance. Bit commitment can solve this problem. In this paper,using public-key cryptosystem based on composite degree residue classes,propose a new bit commitment scheme and prove the feasibility and security of the protocol. In the design of the protocol,introduce algorithmic game theory to guarantee that all players will loyally follow the prescribed game protocols.

A Modified Three-party Poker Protocol

Fan Xiang-kui

Poker protocol realizes the fairness of poker games without the third party's participation.However,the conventional three-party protocol without the presence of the fourth-party could cause unfair poker games if the two players collaborate with each other.In view of this situation,a modified three-party protocol is proposed.Based on the new protocol,all players use their own public keys to encrypt the 54 cards during the first cycling,then duding the second cycling,all players obtain their own cards and decrypt step by step the cards of the opponent on the left,then during the third cycling,all the cards could be decrypted in order to testify the reliability of the algorithm.The comparison experiment of the modified protocol and the conventional protocol shows that the modified protocol could effectively solve the problem of fairness.

Fair online gambling scheme and TTP-free mental poker protocols

Weiliang Zhao, Vijay Varadharajan

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.

Bounded-to-unbounded poker game

Lein Harn, H.-Y. Lin, Guang Gong

The bounded-to-unbounded poker game is a fair poker game that can be played over the Internet. It allows both dealer and player to distribute cards in a fair and secure manner. In addition, the presented protocol assumes that the player is computationally bounded; however, the dealer is computationally unbounded.

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.

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.
