In this study, we define a polyalphabetic cipher method that is called fragmented polyalphabetic (FP) cipher that is based on the fragmented Caesar (FC) cipher. In the FP-cipher, plaintext is encrypted by multiple encryption alphabets which are obtained by using the FC-cipher. We then construct a mathematical modeling and make a computer program of the method.
