Project #1
Name of the Project : Chaotic Cryptography and Secure Communication using

                              Digital Signal Processors (DSPs)

Client :DRDO
Duration :June 2005 – Till date
Project Description

 This is meant for transfer confidential information from one person to another remote person. This information is crypt with chaotic signal, in this cryptography technique is designed by using Digital Signal Processors.     
Signals are processing and evaluating in the Digital Signal Processors (DSP) TMS320C6713 and TMS320C6416. The Information signals (either audio or text) is crypt with chaos signal (nonlinear

signal) and transmitting that encrypted signal in digital manner BPSK (Binary Phase Shift Keying)

techniques. Receive the encrypted digital signal is correlated and separated data’s. That separated

data is decrypted with the chaotic signal to get the actual information.  Here crypt logic and BPSK

coding is written in Code Composer Studio using ‘C’ Language and MATLAB.
Project #2
Name of the Project DNA Cryptography using DSPs.
Client In-house
Duration January 2009 – April 2009
Project Description

 DNA has only four Alphabetical letters (A,C,G,T). There are Lakhs of DNA sequence is available.

So we encrypt our information to any one of the DNA sequence. Our encrypted sequence also the

same A,C,G,T, so no one cant easily find this. We should have some specific algorithm to encrypt and decrypt techniques.
This is also we manipulating, processing and crypt logic coding on ‘C’ for DSPs TMS320C6713.

Project #3
Name of the Project Translation process in Central Dogma.
Client In-house
Duration November 2008 – January 2009

Project Description
 This Central Dogma translation is nucleotide DNA sequence to Protein sequence conversion. To

analysis which protein is in available in DNA.  Coding written using ‘C’ platform.

Project #4
Name of the Project:  Bio-Chemical Analyzer.
Client:   In-house
Duration:  March 2008 – May 2008

Project Description 

The Bio-chemical Analyzer analyses the content of Calcium, Bile-pigment, Glucose and Ketones from

Urine, Blood and etc. Using Infrared ray’s sensitivity reading of above four content to microcontroller AT89C51. Micro controller will send that reading to PC software, this calculates all above reading with

some formulas to display.
Coding written using ‘C’ platform 2.0 with Graphics to shows the analyzed result.
Project #5
Name of the Project:  Logging System Database for Employees.
Client:   In-house
Duration:  November 2007 – January 2008

Project Description 

Using RFID sensors interfaced microcontroller kit (AT89C51) to check the logging information and

monitoring the employee’s status in various department of the company.
Written Employee Logging database software with Graphics using ‘C’ platform 2.0.
Project #6
Name of the Project:  Development board for AT89SXX microcontrollers
Client:   In-house
Duration:  January 2006 to April 2006
Project Description 

The board incorporates almost all the peripherals like RTC, 8 channels ADC, I2CEEPROM, LCD and

7-segment display with full Board support package. An In system programmer is also embedded

on the board through which we can program AT89S5XX microcontroller without the help of an external

programmer which is accomplished using SPI protocol .It can be used as an external programmer

for off-board units.

Project #7
Name of the Project:  Add-on feature for Automatic Teller Machine (ATM).
Client:   In-house
Duration:  August 2005 to November 2005
Project Description 

A costumer can access account through neighbour by giving card alone without password for secret purpose. Then neighbour connect his mobile phone with ATM and call to owner of the card. After

that owner will directly communicate with ATM to access his card.
Using DTMF MT8870 decoder interfaced Microcontroller AT89C2051 kit is connected to Automatic

Teller Machine, for accessing card through phone.
Written Account Database and account accessing selector software with Graphics using ‘C’ platform

2.0.
