Game Anti Plug System Design And Implement

Along with Network game is increasing, the number of Anti plug also growing, more and more people use. Anti plug violated the game operators in the intellectual property, serious damage to the balance of the game, shortening the lifespan of the game. So to protect the safety of the game, maintain the game’s balance is important.This thesis analyzed the domestic and foreign’s Anti plug system and the actual usage of this. The system provides game client, server protection as well as game of vulnerability mining. Game’s protecting in client uses windows driver to scan process trait and report to server. In server it based on switch mirror splitter, capturing game’s communication protocol to match plug’s trait. Game Vulnerability Mining checks the game in safety comprehensively, digs the vulnerability plug can use, prevents from damaging game’s balance. The Secret Scan subsystem in client can scan plug which enable self protection. It’s process trait scan provides three ways that is ActiveProcessLinks, virtual memory, physical memory. It matches plug’s tag which use process’s prototype pte, even if the function of reading process memory was hooked. The Parallel Anti plug subsystem forbids plug refereeing to find multiple behavior trait. Because the plug’s writer cannot contact this subsystem, so to break it’s protection is not easy. The game of vulnerability mining subsystem use Reverse engineering method to disassemble the game logic, with the principle that client computes but server does not compute or compute incompletely to find loopholes, then form security testing documents for game company.This thesis designs and implements the three subsystems,the formation of the comprehensive protection of game system. Self defence, drivers don’t scan using hook technology, will not be bypassed. Client and server communication take game’s connection, with the encryption and authentication in use to protect the communication data. All in all, the thesis demonstrate the Anti plug system not only forbid plug effectively, but also the subsystem in client and server have a good protection.
