SmartX--Advanced Network Security for Windows Opearating System

Abstract

A software framework for secure and efficient communication between two nodes using the Windows Operating system is proposed. The proposed system aims to overcome the drawbacks of virtual private network, by reducing the number of buffer copies and the protocol overhead. It involves only a single copy of the data and a single context switch thus creating a tunnel between the two end points. It uses the patent mutual identity algorithm to secure the two end points of a tunnel. It uses a 128 bit advanced encryption standard algorithm for encryption/decryption. This framework resides on the NDIS (Network Driver Interface Specification). It performs a set of modifications on each network packet which is about to hit the wire. The system eliminates the drawback of VPN system by increasing the throughput and reducing the processing overhead.
