A new mobile on-line mutual authentication scheme

In today's life, the mobile phone is an essential device for the modern human. The people play installed games in the mobile device to pass the time and express emotions. However, stand-alone off-line game may not require internet connection but pro-longed use predisposes bored. Therefore, multiplayer on-line game meets the needs of groups of human activity. In the almost multiplayer on-line games, the player through the mobile network registers an account and connects to game servers to recognize the validity of identity and groups. Meanwhile, the game servers have the ability to identity other plays and assemble different groups consisting of different players. But a single player can registers multiple accounts and joins the designated groups what they want to be. Meanwhile, the players must always be connected to the game server to require on-line players and groups information. These software authentication vulnerabilities could cause the unfair game between players, cheating circumstances and player profile leakage. This paper proposes a new mobile on-line game authentication mechanism which meets a small amount of user following ten players. The proposed mechanism takes advantage of the known public key technique to provide the players convenience of without any time connected to the game server. The player can acquire the unique public key information in the first game software download process. Hereafter, players can apply the public key technique to reach mutual authentication, communication encryption and user information protection functions.
