Fibonacci and modulo principle for hiding information using hill cipher algorithm

Abstract

This digital era makes everyone feel insecure about their privacy, such as information. This is a nowadays problem, but it can be solved with the security system. Cryptography is one of the security systems, which scrambles message using a key. The key is important to process both encrypt and decrypt in cryptography. One of the cryptography algorithms is hill cipher. It is an algorithm which uses symmetric key. In this research, Fibonacci and modulo principle will be used to create the key, and then the key will be used to scramble the message using hill cipher algorithm. Finally, the information can only be opened by people who know the key correctly.
