Enhancing Cryptographic Security using Novel Approach based on Enhanced-RSA and Elamal: Analysis and Comparison

Abstract

Cryptography is generated to create secure data transmission over networks. The algorithm chosen for cryptography should satisfy the conditions of authentication, confidentiality, integrity and non-repudiation. Recent years have witnessed the phenomenal growth of RSA. We design an algorithm to merge both enhanced RSA algorithm and El-Gamal algorithm to provide user with a higher level of data security. The enhanced RSA algorithm enables faster encryption and decryption process and generating public and private key faster than the original RSA. The Enhanced RSA Cryptosystem is based on Integer Factorization Problem (IFP), while the El-Gamal Cryptosystem is based on Discrete Logarithm Problem (DLP). This model works on the basis of combining IFP and DLP.
