Abstract

A New Novel Hybrid Security Algorithm (NHSA) for Rivest-Shamir-Adleman (RSA) cryptosystem was proposed in this paper, which is based on Encryption algorithm using Dual Modulus and Enhanced method for RSA (ERSA) cryptosystem. Here, the computation of public keys and private keys depends on modulus values, each computed using three different prime integers. Thus complexity involved in factorizing the modulus value increases. It improves the security of RSA scheme against Brute Force Attack using double mod operation based encryption and decryption. Therefore, it is not possible to retrieve the original message for the cipher text even after determining a single public key. Also it is difficult to factorize the modulus value into its three prime factors. Thus it enhances the security of encrypted data two times. In this paper, the proposed algorithm is compared with “Encryption algorithm using dual modulus” in terms of key generation time and security of data.
