Abstract

Cryptographyis the process of data hiding from unauthorised users. Historically, the term “Cryptography†has been associated with the problem of designing and analyzing encryptionschemes (i.e., scheme that provide secret communication over insecure communication media). With the growth of internet secure data transmission is more and more essential and important. Sometime single encryption technique is not sufficient to protect the valuable data. We developed a new algorithm which can change the encryptiontechnique with change of plane textpattern to enhance the confusion and as well as diffusion.
