Object Oriented Paradigm for implementing Elgamal Algorithm.

Abstract

The need of exchanging messages secretly over unsecure networks promoted the creation of cryptography to enable in the security of the messages sent over an unsecure network and also to enable only the authorized receivers to interpret the exchanged message. The main goal of the proposed paper is to enable people who do not have the full knowledge of programming language to understand how the proposed system will work and also to enable programmers to implement the Elgamal algorithm using Object oriented approach. It also helps to prevent unauthorized access from interpreting the exchange messages. In the proposed system, Object oriented paradigm is designed to implement a particular public key cryptosystem called the Elgamal Cryptosystem is considered with the help of JAVA Programming language to be used over texts. Since the Elgamal cryptosystem over a primitive root of a large prime is used in messages. This proposed system shows how secure messages are sent over the network, and how the generations of public key is done in an encapsulated way.
