TCP/IP协议安全性研究
摘要:Internet的日益普及给人们的生活和工作方式带来了巨大的变革,人们在享受网络技术带来的便利的同时,安全问题也提上了议事日程,网络安全也成为计算机领域的研究热点之一。由于TCP/IP协议的设计是针对可以信任的环境,所以协议本身存在着许多的安全隐患。本文在介绍因特网中使用的TCP/IP协议的基础上,对TCP/IP协议及其子协议的安全性进行了全面的分析,从理论上分析了协议中几种主要的安全隐患。将网络安全理论与实践结合是提高网络安全性的有效途径。本文利用目前常用的协议分析工具对TCP/IP协议子过程进行了比较深入的分析,并针对TCP/IP协议存在的安全隐患做了一些实际操作和实验。希望能在协议的应用中对使用者能有所帮助。

The Study on TCP/IP Protocol Security
Specialty: Network Engineering SiLi Teacher:FuKaiyao
Abstract:The increasingly popularization of Internet brings great changes to the manners of peoples living and working. As people enjoy the convenience brought by network technology, security issues also come into consideration. As the design of the TCP/IP protocol is in the trusted environment, so itself has many security non-avoidant problem.Network security also becomes one of the research hotspots in the computer domain. This paper mainly focuses on the security of the TCP/IP protocol on the basis of introduction of the TCP/IP protocol and sub-protocol. It also analyzes the several main hidden troubles in this protocol. And it is an effective way to combine the theory of the network security with the practice. This paper studies deeply on the TCP/IP protocol’s sub-process, using the protocol analyzing tools that currently usually used. Many experiments have been done on the hidden troubles in the TCP/IP protocol, and hope to be helpful to the user which are in the protocol application field.
