• A NEW METHOD OF CRYPTOGRAPHY USING LAPLACE TRANSFORM

Abstract

Network security is very important in the internet and other form of electronic communications such as mobile communications, Pay-TV, e- commerce, sending private emails, transmitting financial information, security of ATM cards, computer passwords etc, which touches on many aspects of our daily lives.

In this paper we proposed a new method of cryptography, in which we used Laplace transform for encrypting the plain text and corresponding inverse Laplace transform for decryption. Starting with basic theory of Laplace transforms in section 2, we obtained the main result in section 3. The generalization of the results is included in section 4.This paper is extension of the work of [4].
