新型数字媒体安全支撑平台研究

A discussion on a new-typed digital media security supporting platform

针对目前数字媒体所面临的信息安全问题,该文介绍了一种新型数字媒体安全支撑平台。该平台以网络游戏为依托,包括网络游戏客户端插件、网络游戏服务端插件、安全服务器平台三部分,采用客户端/服务器模式,无缝集成到网络游戏运行环境中,提供反网络游戏客户端各种非法外挂和插件的功能,以保证网络游戏的安全正常运营。该平台采用无线局域网鉴别与保密基础结构(WAPI)所采用的对称密钥算法以保证系统自身通信的安全性,客户端插件采取了文件修改检测、内存检查、鼠标键盘事件截获、非法插件扫描、黑软扫描等有效措施以保证本地安全性。该平台还提供了灵活的、开放的对黑软的处理策略。

In order to solve the problem of information security faced by digital media, this paper introduces a new-typed digital media security supporting platform. Based on online game, the platform including a plug-in in client of online game, a plug-in in server of online game and a security server is integrated seamlessly into the settings of online game running by client/server pattern. It can provide functions of protecting all kinds of lawless cheat plug-in in client of online game so that the online game can run safely and normally. For its security of communication, the platform adopts the symmetrical secret key algorithms used by WLAN Authentication and WAPI Privacy Infrastructure. The plug-in in client takes some effective measures to ensure its local security, such as inspecting the files modification, checking memory, intercepting the events of mouse and keypad, scanning lawless plug-in and hacker software, and so on. Some flexible and opened strategies to deal with hacker software are provided in this platform.
