Secure Data Transfer Based On Conventional Encryption Technique Including Random Number Key Generation

Abstract

In general secure data transfer between two communicating parties is done using several encryption and decryption techniques. But there may be a chance for intruders to attack cipher text even if we use best encryption algorithms. In this paper we propose “Random Number key generation algorithm” that performs transposition on the cipher text, which is generated by encryption and decryption techniques . Using this technique  the cipher text can be strengthened and it would become difficult for the intruders to break it. This technique can be applied before or after encryption, which ever is  appropriate for the application.
