TCP/IP安全性研究
 
摘 要:Internet的日益普及給人們的生活和工作方式帶來(lái)了巨大的變革，人們?cè)谙硎芫W(wǎng)絡(luò)技術(shù)帶來(lái)的便利的同時(shí)，安全問(wèn)題也提上了議事日程，網(wǎng)絡(luò)安全也成為計(jì)算機(jī)領(lǐng)域的研究熱點(diǎn)之1。本文在介紹因特網(wǎng)中使用的TCP/IP協(xié)議的基礎(chǔ)上，對(duì)TCP/IP協(xié)議的安全性進(jìn)行了較為全面的討論，從理論上分析了協(xié)議中幾種主要的安全隱患，然后在分析有關(guān)安全協(xié)議的研究成果的基礎(chǔ)上，提出了將數(shù)據(jù)包的數(shù)據(jù)部分加密傳輸并對(duì)報(bào)頭部分加以認(rèn)證的方法等以保障安全的觀點(diǎn)。將網(wǎng)絡(luò)安全理論與實(shí)踐結(jié)合是提高網(wǎng)絡(luò)安全性的有效途徑。本文利用目前常用的協(xié)議分析工具對(duì)TCP/IP協(xié)議子過(guò)程進(jìn)行了深入的分析，并針對(duì)TCP/IP協(xié)議存在的安全隱患做了大量的實(shí)際操作和實(shí)驗(yàn)。希望能對(duì)未來(lái)的信息社會(huì)中網(wǎng)絡(luò)安全環(huán)境的形成有所幫助。

The TCP/IP Security Research
 
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. 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. It also analyzes the several main hidden troubles in this protocol. By analyzing the achievements in the research of the related securce protocol，it draws such a view that the data field of a packet should be encrypted and the head field of the packet should be authenticated to ensure security. 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 form a network security environment in the coming information society.
