• CRYPTOGRAPHY BY APPLYING SUMUDU TRANSFORM TO TRIGONOMETRIC SINE FUNCTION

Abstract

In this paper we introduce the application of Sumudu transform & inverse Sumudu transform in the process of encryption &decryption (i.e Cryptography) respectively. In the first part of the paper we consider one plain text and convert it to clipher text by applying Sumudu transform to trigonometric sine function and in the second part we convert clipher text to plain text by applying inverse sumudu transform. Finally we generalize some results for encryption and decryption.
