New Multiphase Encryption Scheme for Better Security Enhancement

Abstract

With the progression of technology, nowadays, it becomes essential to communicate through unsecure open network. Several researchers have proposed various methods to conceal the messages in order to securely transfer them. In this paper, we propose a new multiphase encryption method which combines the modified Caesar cipher, Atbash Cipher, and XOR cipher, where the encryption is done in multiple phases. It also utilizes the polyalphabetic substitution concept to enrich the encryption process.
