Abstract: This paper proposes a cheat-detection mechanism based on delta state for P2P MMOG. A player’s delta state in other players’ game views is measured by definite integral. It determines whether the player is cheating or not, according to the delta state and taking network delay in reference. Judgment standard is decided by thresholds. Simulation results show that the cheat-detection mechanism can detect this kind of cheating which will induce state inconsistent between other players effectively, so that security of MMOG is enhanced.

Key words: MMOG, cheat-detection, delta state

摘要： 提出一种适合P2P MMOG的基于状态差的欺骗检测机制。采用定积分对某玩家在其他玩家游戏视图中的状态差进行量化，并在参考网络延迟的基础上根据状态差判定该玩家在游戏过程中是否进行了欺骗。判断标准为既定阈值。实验结果表明，该文提出的欺骗检测机制能有效检测出导致玩家状态不一致类型的欺骗，提高了游戏的安全性。
