The Art of Secrecy: Hybridizing Caesar and Columnar Ciphers for Enhanced Data Security

Abstract

Cryptography is currently the most secure way for transmitting data on the Cloud. It employs one or algorithms to securely transport data, preventing any unauthorized access or loss. An assortment of researchers has devised numerous protocols related to secure data transmission. Each method entails transforming data from an accessible format to an inaccessible one. However, more than these approaches are needed to ensure absolute information security. In the context of data security, each algorithm is susceptible to vulnerabilities. Ensuring the implementation of adequate data security protocols will effectively protect the encrypted data against any decryption attempts by malicious actors. An attempt to modify the data will render the assailant incapable of recovering the original and causing damage. This article introduces an innovative method that integrates the substitution cipher and transposition ciphers to guarantee data confidentiality and integrity during transmission and communication. By contrasting our work with prior research, we have demonstrated that the proposed algorithm outperforms the existing cypher schemes. At the end, a conclusion is subsequently attained through a comparative analysis.
