• A NEW METHOD OF CRYPTOGRAPHY USING LAPLACE TRANSFORM OF HYPERBOLIC FUNCTIONS

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 developed a new algorithm for cryptography, in which we used Laplace transform of hyperbolic functions 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 results in section 3. The generalization of the results are included in section 4. This paper is based on the work of [5], A. P. Hiwarekar and [6], G. Naga Lakshmi, B. Ravi Kumar and A. Chandra Sekhar.
