Abstract

In this study, we define a cipher method that is called fragmented Caesar cipher method that based on the basic logic of Caesar cipher. This new method has more possibility then the classical Caesar cipher because of the fragmented alphabet is used to cipher. We then construct a mathematical modeling and make a computer programs of the method.

Keywords
