Cross-Crypto Algorithm: Leveraging the Features of the ROT13 and Vigenere Ciphers

Abstract

Nowadays, the Internet has become the primary option for conducting business transactions, accessing various services, and communicating. Being online also brings cybersecurity threats that have been rapidly increasing. Various security techniques and cryptography schemes have been employed to safeguard our systems and online transactions; however, some of these techniques might be unreliable or insufficient. This paper deals with the integration of features of the ROT13 algorithm and Vigenère ciphers to form a cross-crypto algorithm for encrypting and decrypting the files or information that we intend to transmit online. The proposed technique employs a two-stage encryption process, leveraging the features of both the ROT13 and Vigenère cipher algorithms.
