Performance Evaluation of Wireless IPsec VPN

When the wireless communications is coming to the offices and the homes, security has always been a significant issue. Today there is continuously growing markets for the wireless LANs, but there is big black hole in the security of this kind of networks. There is currently enormous interest in the design of secure wireless networks. In wireless networks free-space radio transmission makes eavesdropping easy and may result in unauthorized access. Virtual Private Networks (VPN) have emerged as a solution. VPN is a network that employs encrypted tunnels to exchange securely protected data. This paper gives an overview of security issues. The primary objective of paper is to present the implementation of a secure IPSec wireless VPN and evaluates its performance.
