• A NOVEL ENCRYPTION SCHEME FOR SECURE COMMUNICATION USING MEALY MACHINE

Abstract

Many mathematical models are taking an active role in the process of encryption and inverse of an element or of a function resulting in decryption process. The main idea behind such constructions is designing a mathematical function in such a way that tracing the inverse of the function is not easy. Cryptography is the art of coding & decoding information.  It is used as security mechanism in electronic communication. The message we want to send is called ‘plain text’ and the disguised message is called the cipher text.  The process of converting plain text into cipher text is called ‘encryption’ and the reverse process is called ‘decryption’.

In this paper, we develop a finite state machine for the process of encryption.
