A New Modified Version of Standard RSA Cryptography Algorithm

摘要

Data security is an open research challenge due to the rapid evolution in communication over an unsecured network. In this direction, cryptographic algorithms play an important role in providing the data security against malicious attacks. This paper elaborates a new asymmetric cryptography approach, i.e. modified RSA algorithm. This proposed method reduces complex calculation involved in RSA algorithm. A novel algorithm has been proposed for finding the value of public key (k) and private key (l). Also, a newly derived formula is used to find the ciphertext (N) and plaintext (M). We have explored some major research challenges in the field of RSA algorithm.
