A New Type of Network Security Protocol Using Hybrid Encryption in Virtual Private Networking

E. Ramaraj and S. Karthikeyan

Abstract

Today wireless communications is acting as a major role in networks. Through year-end 2006, the employee's ability to install unmanaged access points will result is more than 50% of enterprises exposing sensitive information through the wireless virtual private networks (VPN). It enables you to send the data between two computers across a shared or public network in a manner that emulates the properties of a private link. The basic requirements for VPN are User Authentication, Address Management, Data Compression, Data Encryption and Key Management. The private links are established in VPN using Point-to-Point Tunneling Protocol (PPTP) and Layer-Two-Tunneling Protocol (L2TP). These protocols are satisfies VPN requirements in five layers. In user authentication layer, multiple trusted authorities using Extensible Authentication Protocol (EAP) do the authentication process. In fourth layer the data encryption part using RC4 called Microsoft-Point-to-Point Encryption (MPPE) method. The aim of this paper, instead of multiple trusted authorities we focus single trusted authority using public key cryptography RSA in EAP and also we include AES-Rijndael stream cipher algorithm instead of RC4 for MPPE. We propose new type of hybrid encryption technique using AES-Rijndael for encryption and decryption and RSA used for key management.
