Abstract
An Algorithm is considered computationally secureif it can not be broken with standard resources, either currentor future. In this paper we have introduced a new block cipheralgorithm named X-MODDES. It is unique independentapproach which uses several computational steps along withstring of operators and randomized delimiter selections byusing some suitable mathematical logic. X-MODDES isspecially designed to produce different cipher texts by applyingsame key on same plain text. Thus a new protocol has been ....etc

Abstract
To encrypt a text _le and to decrypt the encrypted form of the _le to get the original input text _le. This encryption and decryption is done using the most widely used private key encryption scheme based on data encryption standard (DES) adopted in 1977 by National Bureau of Standards.It was designed by IBM based on their own Luci_er cipher and input from NSA.For DES, data are encrypted in 64-bit blocks using a 56-bit key. The algorithm transforms 64-bit input in series of steps into a 64-bit output of cipher text. The same steps, w ....etc

Data Encryption Standard (DES)
• Financial companies found the need for a cryptographic algorithm that would have the blessing of the US government (=NSA)
• First call for candidates in May 73, followed by a new call in August 74
• Not very many submissions (Why?)
– IBM submitted Lucifer
• NSA worked with IBM in redesigning the algorithm
DES
• DES became a federal standard in November 76
– NBS (NIST) hardware standard in January 77
– ANSI X3.92-1981 (hardware + software)
– ANSI X3.106 ....etc

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 ....etc
