DEAL


In cryptography, DEAL (Data Encryption Algorithm with Larger blocks) is a block cipher derived from the Data Encryption Standard (DES). The design was proposed in a report by Lars Knudsen in 1998, and was submitted to the AES contest by Richard Outerbridge (who notes that Knudsen had presented the design at the SAC conference in 1997). DEAL is a Feistel network which uses DES as the round function. It has a 128-bit block size and a variable key size of either 128, 192, or 256 bits. For key sizes of 128 and 192 bits, the cipher uses 6 ....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

Aim:
To write a C# program to perform encryption and decryption of the given data.

Algorithm
ALGORITHM FOR ENCRYPTION:
Step 1: Declare the class as encrypt_class.
Step 2: Start the main function.
Step 3: Declare the variable str in string data type.
Step 4: Create the object for inbuild encryption
algorithm TripleDESCryptoServiceProvider.
Step 5: Create the data file using Filestream
class.
Step 6: Create the object for class cryptoStream.
Cryptostream is a class to ....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

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

in this project need to designe a circuit which contains a micro controller which Sends the serial data through its serial port every time after resetting. Then it sends the data by RF using DTMF tones.
Now after transmitting the data micro controller wait for some time and then again transmit it.

Information transmission by IR:-
These informationâ„¢s are pre feeded into the microconrollers ROM and by using infrared LED in the following way :-
As we know that sensors only detects 38 KHz IR signal so we modulate the 38KHz signal ....etc
