Enhancing Security for Cryptographic Algorithms

• Wireless Networks have become increasing popular in the communication industry.In emergency applications such as rescue and mission and military applications,there is a need to deploy a wireless network that can be formed instantly.Ad-hoc Network is one such type of network.Ad-hoc networks are autonomous networks comprised of wireless mobile devices.Exchange of sensitive information over access paid services and unprotected wireless links demand the deployment of security in wireless networks.In recent years,secure communication has become an important subject of research.The Main security service for wireless network is to provide confidentiality,authentication,authorization and data integrity.Securing data in a communication network is a challenging task.

• The main Objective of this project is to achieve more data security with minimum computation overhead.The Security method used in this project with minimum computation overhead.The security method used in this project can also be applied to audio and video files.The Present scenario uses different types of encryption algorithm to provide security.In Addition to the existing algorithms,this project provides a method to futher enhance the level of security.This Project uses Network simulator to perform the simulation of the proposed method.
