Secure VPN Based on Combination of L2TP and IPSec

This report is written to provide a method of building secure VPN by combination of L2TP and IPSec in order to meet the requirements of secure transmission of data and improve the VPN security technology. It remedies the secured short comes of L2TP Tunneling Protocol Tunneling Protocol and IPSec security. Simulation and analysis show that the construction method can improve the security of data...

Simple-VPN: Simple IPsec Configuration

The IPsec protocol promised easy, ubiquitous encryption. That has never happened. For the most part, IPsec usage is confined to VPNs for road warriors, largely due to needless configuration complexity and incompatible implementations. We have designed a simple VPN configuration language that hides the unwanted complexities. Virtually no options are necessary or possible. The administrator speci...

IPsec-based end-to-end VPN deployment over UMTS

Next generation mobile users require flexible security mechanisms, which provide customized security services to data traffic, take into account end-user mobility and mobile network characteristics, and are available anywhere–anytime. An IPsecbased end-to-end Virtual Private Network (VPN) deployment scheme over the Universal Mobile Telecommunication System (UMTS) is proposed and analysed. The U...

IPsec/VPN security policy correctness and assurance

With IPSec/VPN policies being widely deployed, how to correctly specify and configure them is critical in enforcing security requirements. Under current practice, IPSec/VPN policies are usually specified manually by system administrators and thus prone to errors. However, dynamic aspects in the network may interfere with the existing policy set up and thus cause unexpected conflict. To deal wit...
