Abstract
In some communication network, we need to secure the information’s travels in the communication channels. To do that we must en information in order to be unseen for any unintended receive interferer.
In this scientific report, we will develop a code that is simulated 01 Programmable Gate Array (FPGA) to. Encrypt the information
befo. sent through the communication channel using a method called DES.
DES stands for Data Encryption Standard. It is widely used to. encryp1 the internet networks. The DES is developed by programming langue encrypt data of the software applications like deals between the custom the bank that take place in the internet.
We will develop hardware module called DES to encrypt the output data any hardware device and decrypt the input data to any hardware• devio DES encrypts and decrypts 64 bit blocks of data, so the DES module mt be used alone to encrypt or decrypt the data but it must be instant~ higher module in the hierarchy. The function of this higher module divide the outgoing data into 64 bit blocks before being encrypted idea transmission or to assemble the 64 bit blocks of data after being decll and deliver them to the intended receiver incase of reception. .
So, the aim of this scientific report is to develop the DES core in o.r1 generalize the use of the DES algorithm to any type of commune
