Keywords : Information Security, Cryptography, Public key, Diffie Hellman, RSA


Abstract

The area of Information Security plays an important role in protecting the confidentiality of electronic data. Cryptography is a field of Information Security where a sender’s message gets encrypted and the message gets decrypted at the receiver’s end. This paper critically analyses the Diffie Hellman Key Exchange protocol and the RSA algorithm, the two most popular techniques that are part of Public Key Cryptography. In this paper, we also introduce an approach to combine the Diffie Hellman Key Exchange protocol and RSA to build a more efficient cryptographic scheme where the public key will be masked in order to provide an extra layer of security.
