📄 Abstract
Nowadays, the Internet is rapidly expanding. As a result, massive amounts of data are transmitted through the Internet via networks. This information must be safeguarded. Cryptography is a technique for ensuring data security and confidentiality by transforming it into an unreadable format. Along with data security, it is also necessary to assure data authenticity, confidentiality, and protection. Because we rely so much on data, we must likewise improve our understanding of data security risks. Cryptography is an example of a data security technique. Cryptography is a Greek word that refers to the art of securing data by converting it into a jumbled and unreadable state. In this research, we use the Polybius Cipher with a modified Vigenere Cipher to create hybrid cryptography. When compared to separate ciphers, the hybrid cryptography system is more secure. We improve the Vigenere cipher key generation by removing some of its shortcomings.
