FPGA Implementation of Secret Communication

The aim of this project is to communicate the data Secretly using DES Algorithm,(i.e) we first send the data (plain t ext) and the key which is of 64 bit into the encryption process. The output of this process will be cipher text. This cipher text is then fed into the decryption process and then the data (plain text) is got as output. The main aim is that since we add the key and shuffle the data it is very hard for the unknown person to find o ut the original data. Since for each key there will be a change in t he cipher text and so the person has to know the key in order to find out the original data.
