CRYPTOGRAPHY – ‘THE MATHEMATICS OF ENCRYPTION’ BASED ON LAPLACE TRANSFORM

ABSTRACT

Cryptography plays an indispensable and very crucial part in various fields of technology. Cryptography is an important tool that evades the threat against possible attacks by hackers during transmission of the message. Since the invent of communication system, information protection has been the first and foremost need of humans. In modern world inspired by technology, security of information and communication becomes all the more important for existence. Cryptography is one of the most important techniques used for protection of transmission of messages and protection of data. It is widely used in e-commerce, mobile communications, emails, business transactions, transmitting financial information, security of ATM cards, computer passwords etc. Cryptography means safeguarding the information by hiding it. It is done through mathematical technique or we can say Mathematical modelling. Laplace transform has many applications in various fields. Here we are going to discuss its application to cryptography. An attempt has been made in this paper to show how we can use Laplace transform of suitable polynomial for encrypting the plain text and apply corresponding inverse Laplace transform for decryption.
