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

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

IMPLEMENTATION OF ADVANCED ENCRYPTION STANDARD (AES)

(This is my Seventh Semister Major Project)

In the past, cryptography helped ensure secrecy in important communications, such as those of government covert operations, military leaders, and diplomats. Cryptography has come to be in widespread use by many civilians who do not have extraordinary needs for secrecy, although typically it is transparently built into the infrastructure for computing and telecommunications.

Advanced Encryption Standard (AES) is an algorithm for performing ....etc

CRISP-DM (CRoss-Industry Standard Process for Data Mining )



Why Should There be a Standard Process

The data mining process must be reliable and repeatable by people with little data mining background.
Framework for recording experience
Allows projects to be replicated
Aid to project planning and management
“Comfort factor” for new adopters
Demonstrates maturity of Data Mining
Reduces dependency on “stars”

CRISP-DM

Non-proprietary
Application/Industry neutral
Tool neutral

Introduction
In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the us government, and is expected to be used worldwide and analysed extensively, as was the case with its predecessor, the Data encryption standard(DES). It was adopted by National institute of standard and technology(NIST) as US FIPS PUB 197 in November2001 after a 5-year standardisation process The cipher was developed by two Belgian cryptographers, Joan Daeman andVincent Rijamean, and submitt ....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

Standard Data Buses And Networks

Definition:
Many systems have a data or bus or network to communicate with other circuit boards or devices known as data bus.
The data bus or network is the backbone of design and represents a significant portion of the system architecture.

Bus Architecture Concerns


Drive configuration

Termination

Signal handshakes etc

Serial Communication

Simplex mode

Half Duplex Mode ....etc
