Multi-Modulus RSA Algorithm ( MuMRSA )

Cryptography defines different methods and technologies used in ensuring communication between two parties over any communication medium is secure, especially in presence of a third part. This is achieved through the use of several methods, such as encryption, decryption, signing, among many others. Cryptography uses a key, or some sort of a password to either encrypt or decrypt a message that needs to be kept secret. This is made possible using two classes of key-based encryption and decryption algorithms, namely symmetric and asymmetric algorithms. The best known and the most widely used public key system is RSA. This algorithm comprises of three phases, which are the key generation phase, encryption phase, and the decryption phase. Owing to the advancement in computing technology, RSA is prone to some security risks. It is assumed nowadays that 1024-bit number will be factored by 2020 and will be not secured enough to stand against the factorization attacks. This paper previews a model of an enhanced RSA algorithm using multiple modulus numbers (n). The proposed model improves the security of the RSA since it has multiple mod operations as well as it includes multiple public and private keys.
