基于ipsec協(xié)議的linuxvpn網(wǎng)關(guān)平臺畢業(yè)設(shè)計(jì)

1、i基于基于IPSec協(xié)議的協(xié)議的LinuxVPN網(wǎng)關(guān)平臺網(wǎng)關(guān)平臺摘要：摘要：因特網(wǎng)協(xié)議安全(IPSec)是一系列建立在網(wǎng)絡(luò)層最頂端的協(xié)議，通常被用來建立虛擬隧道，最廣為人知的是虛擬專用網(wǎng)絡(luò)(VPN)。虛擬專用網(wǎng)絡(luò)(VPN)在公共網(wǎng)絡(luò)，如因特網(wǎng)中擴(kuò)展出一個(gè)私有網(wǎng)絡(luò)。它使計(jì)算機(jī)通過共享的或公共的網(wǎng)絡(luò)來發(fā)送和接收數(shù)據(jù)就好像它是直接連接到私有網(wǎng)絡(luò)，而且受益于私有網(wǎng)絡(luò)的功能性、安全性和管理政策。本次課題中，論文首先對IPSecVPN的背景和原理進(jìn)

2、行了一些簡單的介紹，接著論文介紹了VPN網(wǎng)關(guān)實(shí)現(xiàn)的具體步驟及功能。本次課題使用了Linux系統(tǒng)這個(gè)免費(fèi)開源的平臺用來作為VPN網(wǎng)關(guān)。通過在一個(gè)Linux系統(tǒng)上搭建VPN服務(wù)器來充當(dāng)VPN網(wǎng)關(guān)并采用了xl2tp協(xié)議進(jìn)行數(shù)據(jù)傳輸，在另一個(gè)Linux系統(tǒng)上搭建web以及ftp服務(wù)用來充當(dāng)私有網(wǎng)絡(luò)。最后用一臺Windows充當(dāng)公共網(wǎng)絡(luò)中的一臺主機(jī)，通過撥號直接連入VPN網(wǎng)關(guān)，對私有網(wǎng)絡(luò)的web以及ftp實(shí)現(xiàn)訪問。本次課題的成功展示出了IPSec

3、VPN在傳輸數(shù)據(jù)方面的良好的安全性、網(wǎng)絡(luò)功能和管理性能，同時(shí)也展現(xiàn)出了IPSecVPN良好的研究應(yīng)用價(jià)值和開發(fā)前景。關(guān)鍵字：關(guān)鍵字：Linux；虛擬專用網(wǎng)絡(luò)；IPSec；網(wǎng)關(guān)；xl2tpiii目錄目錄摘要摘要....................................................................................................................
