Perancangan Aplikasi Kriptografi Simetris Menggunakan Algoritma Hill Cipher dan Advanced Encryption Standard

The process of sending data is done such as internet media, or other media. Basically sending the data without any security to the content of the data sent, so that when tapped on the delivery flow then the data tapped can be directly read by the tapper. For that required software as a supporter using an encryption method (Cryptography) so that the message contained in the data sent to be more secure. This research using a form of literature study and experiment. The data collection techniques used in this research is literature study to obtain Hill Cipher cryptography theory and Advanced Encryption Standard (AES). While the method of software design using Waterfall because the process of software development in sequence, Where progress is seen continually flowing down through the phases of analysis, design, implementation, testing and maintenance.This design result generates a symmetric cryptographic application using Hill Cipher algorithms and Advanced Encryption Standard (AES).With this device, confidentiality and authenticity of information will be more awake
