FPGA IMPLEMENATAION OF DATA ENCRYPTION STANDARD
OBJECTIVE
The main aim of this project is to design FPGA based cryptography which encrypts / decrypts the data from the PC to PC . In this project the encryption / decryption algorithm is designed and programmed in to the FPGA and data transfer between the PCs is controlled by the FPGA.
DESCRIPTION
The plain text from PC 1 is converted to binary format and transferred to the FPGA kit through the serial port . The internal buffer collects the data from PC 1 and according to the function like (encryption / decryption ) block will be selected . The encryption and decryption algorithm used in our design in based on AES . The output of the encryption block is called chiper text or cryptogram wile be transferred from Pc1 in order to decrypt the data . The output of these blocks are stored in the output buffer and then transferred to another PC through serial port .
