“…Panda and Chattopadhyay found out that RSA algorithm was easy to factorize since modulo n used is the product of two prime numbers only and therefore making it easy to obtain the decrypted original message [5]. Other researchers who pinpointed several limitations in regard to RSA algorithm included Mathur et al [6] who delved in to improving the model by enhancing security and elimination of redundant messages using K-nearest neighbor algorithm.…”

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, generating of pseudo-random numbers, 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, which makes it less secure. The following paper preview different proposals on different methods used to enhance the RSA algorithm and increase its security. Some of these enhancements include combining the RSA algorithm with Diffie-Hellman or ElGamal algorithm, modification of RSA to include three or four prime numbers, offline storage of generated keys, a secured algorithm for RSA where the message can be encrypted using dual encryption keys, etc.

“…In the same year [22] broke down that Cryptographic natives were vital building hinders for outlining security conventions to obtain classification, verification, uprightness and non-denial. In 2017 [23] recommended that Cryptography was a way to deal with secure data from gatecrashers. It gave guarantee, as well as gave credibility.…”

Vehicular Area Network (VANET) plays an important role in today's demand of smart roads where the traffic needs to be monitored for safe commuting along with it, the commuters should also be given facilities in case of an emergency or otherwise. Keeping in mind the challenging requirements of the present and the future, in this paper work first previous solutions were reviewed and a new Secured Protocol for VANET with Signature Verification has been proposed. Modified Hill cipher and RSA algorithms are used in sequence to secure the Vehicle's information transmitted to the Road Side Unit(RSU). Signature verification has been taken care of using Baker's map. MD5 hashing has been also used to ascertain that there was no intrusion. The device in the vehicle and the RSU communicates only when the signatures are verified. A comparative analysis has also been presented where it has been observed that the proposed algorithm performs better than simple RSA algorithm. The results obtained shows an improvement in Bandwidth by 16%, energy consumed is reduced by 14% and time reduced by 5%.The results indicate that the proposed method not only secures the privacy of the commuters but also uses lesser resources. It can be concluded that the proposed three tier secured structure is more robust than the existing models.

Abstract: RSA Algorithm is one of the widely used asymmetric cryptography. But with several conducts of the different studies, factorization attack based on the value of modulo 'n' and based on the public key, the value of the private key is vulnerable. With this, the study modified the RSA Algorithm based on modulo and the public key. The modulo transformed into a new value that produced a compound result in the factorization process. At the same time, the public key has been modified by choosing randomly from collected values and transformed to a different value making it a better-hidden private key. The two algorithms compared in terms of factorization, encryption and decryption, and speed . The modification of the RSA Algorithm based on modulo and public key produced a new two-tier scheme in terms of factorization, and encryption and decryption process. The new scheme in the result is resistant to factorization and has a new scheme of private key hiding.
