Performance Analysis of Various Protocols on Virtual Private Network for IPSec

Abstract

Many Corporations are seriously concerns about their security of network. Virtual private network is commonly used in business situations to provide secure communications over public infrastructure such as internet. VPN is proven technology that does provide security strong enough for home use and business use. VPN network allow two or more parties to communicate secure over public network using cryptographic algorithms and protocols In this paper we analyze the performance of protocols on TCP and Ftp in VPN router network on different data sizes and calculate the throughput of files on different encryption algorithms and then the result is compared to determine the performance throughput. Keywords: VPN, IPSEC, DES, MD5, SSL, PPTP, Encryption.
