Cheat Proofing Stop and Wait Synchronisation Using a Supervising Node

Abstract

Networked online games are increasingly becoming attractive to many players. Multiplayer role-playing games need to incorporate several techniques to prevent any foul play or cheating. The multiplayer nature and network latency are still challenging the level of security provided in real time games. In this paper we introduce the main concepts of real time game environments, and overview the classification of cheating in games. We analyse various game architectures and investigate time based cheats and available cheat proof protocols. A cheat proof protocol with no performance penalties is developed and analysed. The proposed technique relies on the supervision of a trusted supervising node.
