TCP协议下的网络数据流的实时替换框架设计与实现

TCP Protocol Network Data Stream Real-time Substitution Frame Design and Realization

随着计算机网络飞速发展,常见的攻击手段之一就是网络数据替换。网络数据实时替换相对于一般替换手段具有自己的特殊性,攻击者的替换行为使得通信双方无法正确接收数据包,或无法进行数据包的重组。本文在TCP协议的基础,提出了4种通信介入方法,构思了整体的替换框架,如何对攻击者的行为加以修正,并强调了替换策略应用的辩证关系,实现了轻量级的控制服务端,并从防御的角度提出了对实时替换的预防和识别方法。

With the rapid development of computer networks, common attack means is one of the network data transmission. Network real time data for relative to the general replacement method has its own particularity, the substitution behavior makes communication parties can not correctly received data packets, or is unable to carry on data packet reorganization. This paper is based on TCP protocol is presented, four kinds of communication intervention methods, the idea of the overall substitution frame, how the attacker＇s behavior to be modified, and emphasized the replacement strategy application of dialectical relations, and achieve a lightweight control server, and from the angle of defence proposed to replace the prevention and identification method in real time.
