Abstract

Cryptography is a field of science that has a technique or art of disguising the data sent by the sender to the recipient to maintain the authenticity and integrity of the data. The Generalization of the ElGamal algorithm is the latest derivative of the ElGamal algorithm, which has security difficulties by relying on discrete logarithms. Unlike the Multi-factor RSA Algorithm, a variant of the RSA algorithm based on a modified modulus structure from ordinary RSA, it relies on factoring a huge integer into its prime factors. This study uses the Python programming language to compare the ciphertext enlargement of the two algorithms with the same prime number digit length.
