AB  - The advancement and sophistication of technology in the present era have resulted in millions of people interacting and sharing data through the internet using various platforms such as email, chat applications, and others. This has led to the dissemination of personal information and data worldwide through the internet, which also poses the possibility of data interception by unauthorized parties. Data breaches occur when data is not securely protected. One way to secure data is by using the concept of cryptography. In this paper, a modification will be made to the classical cryptography algorithm, Hill Cipher, by incorporating the chaos function of Henon Map in generating unimodular key matrices. Based on the design and development results, the modified algorithm of Hill Cipher is capable of securing data quite effectively with a sufficiently large key space and a wide encryption set. The modified algorithm of Hill Cipher will be implemented in a data sender application.
