An Improved Algorithm for Designing Secure Point-to-Point Wireless Environment

Abstract

The goal of this paper is to be an easy to follow guide for configuring and securing a wireless network in a windows environment. Security has been one of the most important issues in wireless communication. Encryption of messages into cipher text is one of the techniques to provide security up to some extent but, it also causes another problem, i.e., how to safely and confidentially encrypt and deliver security keys so that hackers have to spend a very long time before they can decrypt the cipher text. In this paper our main aim is to devise a secure point-to-point encryption method for a wireless communication environment. Novel Diffie-Hellman-based Public Key Distribution System has been implemented, which adopts a stream cipher technique to encode plaintext with a pseudo random number sequence. We have verified the proposed method and simulation results show that the performance of this method can meet users’ communication needs. Also it’s a system with high complexity and unpredictability from the consecutive creation of increasingly positive real value sequences to the final output of random numbers. 98 % of the random numbers produced passed 60,000 tests determined by Federal Information processing Standards Publication.
