Add-on Security Level for Public Key Cryptosystem using Magic Rectangle with Column/Row Shifting

In today’s world, security is required to transmit confidential information over the network. Security is also demanded in wide range of applications. Cryptographic algorithms play an important role in providing the data security against malicious attacks. The efficiency of cryptographic algorithm is not only based on its time taken for encryption and decryption, and it also accounts for number of stages used to obtain the cipher text from a plain text. Rivest-Shamir-Adleman (RSA) algorithm is a popular encryption scheme that guarantees confidentiality and authenticity over an insecure communication channel. However, several attacks are introduced to break the security of these algorithms due to certain constraints. Also, it may not be guaranteed that the cipher text is fully secured. One such limitation in the pas
