P. Srinivasarao | B. Chaitanya | K. Venkatesh ^[5]

Abstract: A day-to-day use of cryptography in our life is increasing tremendously; this is because of necessity of our multimedia documents to be protected from unauthorized person. As the days are passing the old algorithms are not remained so strong as cryptanalyst are familiar with them. Today the computers are faster and in feature its speed will increase more and more. Brute force attacks are made to break the encryption and they are growing so faster. These attacks are the main drawbacks of older algorithm. But with feature this algorithms will be replaced by new techniques that will provide better protection. In this paper we are going to proposed new encryption technique which is more faster, better immune to attacks, more complex, easy to encrypt and many more advanced security feature included. This Document displays the comparison between PSR algorithm and RSA Algorithm which are used in the encryption of plaintext into cipher text that are generally used in cryptography.
