INFORMATION SECURITY OF PLAIN TEXT USING PUBLIC KEY CRYPTOSYSTEM

Abstract

Cryptography is the practice and considers the strategies for securing communication and information within the presence of adversaries. In this paper introduced the modified RSA for multiple prime numbers for data encryption. The strategy which is used in this cryptosystem is an asymmetric RSA algorithm. This method has two public and private keys. The proposed algorithm also implements on text data and also used six, eight, ten, and twelve prime numbers in place of four prime numbers to gain security and “n” prime numbers are not smoothly factorized and enhanced the efficiency. The objective of this technique is to improve the security of the modified RSA through decryption procedure by implementing a multiple prime numbers algorithm to find the value of the decryption key that will further enhance the security of the decryption process.
