WIRELESS COMMUNICATION
Secret Message Transfer System for Military Applications
ABOUT THE PROJECT Our aim of the project is to protect the data from the ensnares. The
proposed system is generally used in security systems specifically for
border or defense or military security applications.
In such circumstances, generally the Military Chief do not have a
flexible communication system as well as they aren’t supposed to have
voice enabled communication systems.
The base station is elsewhere wherein all the efficient
communication methods are available and prevailing. But at
the borders, a single room or communication environment
isn’t available. In such a scenario, we need an efficient
communication strategy with utmost secure mechanism.
There exists lot of encryption – decryption algorithms
prevailing already, but every such algorithm has certain flaws
either facing a threat in the communication channel or the
methodology of transmission or the bandwidth.
To accomplish this, we have used a PC as a sender
The computer will Encrypt the data using generating a
duplicate Character for a real one.
The message to be sent is fed in to the computer for different units. The computer will encode
the data using PSEUDO RANDOM BINARY SEQUENCE by generating a 7-bit access code for
each units and the code will be sent along with the mixed data of other unit’s message also
At the receiving end the key is accessed and entered and then
the microcontroller will then decode the Received data and
separates the data for different units and displays the
message on the display. The communication takes place
through RS232 Port, using RF frequency transmitters and
receivers
Military Systems that
process classified
information must operate
in a secure manner; that
is, they must adequately
protect information
against unauthorized
disclosure, modification,
and withholding
