Improved RSA Cryptosystem Based on the Study of Number Theory and Public Key Cryptosystems

Security is required to transmit confidential information over the network. Security is also demanding in wide range of applications. Cryptographic algorithms play a vital role in providing the data security against malicious attacks. RSA algorithm is extensively used in the popular implementations of Public Key Infrastructures (PKI). In asymmetric key cryptography, also called public key cryptography, two different keys (which form a key pair) are used. One key is used for encryption and only the other corresponding key must be used for decryption.
