Penerapan Kriptografi Menggunakan Caesar Cipher Dan Vigenere Cipher

Abstract

In ensuring the confidentiality and security of a data cryptographic method is needed, which is a method for maintaining confidentiality of information. Basically the data without any security to the data provided, so that when tapping the flow of the sender, the data taken cannot be read directly by the tappers. For this reason, software is needed to support certain methods so that the sent message becomes safer.In this study the author uses a form of literature study and experiment research. While the software design method uses the Prototype method because the software development process emphasizes a short development cycle.The data collection technique uses documentation and observation studies to obtain the theory of Caesar Cipher and Vigenere Cipher. The use of Caesar Cipher and Vigenere Cipher methods is quite fast in the process of encryption and decryption in a data collection.Software design using the NetBeans IDE programming language design results obtained in this study can be seen in the research results chapter which will show all the processes in this application
