OFDM Based Wireless Encryption and
Decryption Message Transfer System for
Military Applications using BlowFish
Algorithm
What is OFDM Short for Orthogonal Frequency Division Multiplexing, an FDM modulation
technique for transmitting large amounts of digital data over a radio wave. OFDM
works by splitting the radio signal into multiple smaller sub-signals that are then
transmitted simultaneously at different frequencies to the receiver. OFDM reduces
the amount of crosstalk in signal transmissions
Need:
The need for this project arises when we want the data communication to
be protected from others. This is highly essential in the military field and
especially during war times. Because during war periods when a particular
army wants to send a message to remotely located units, which belong to
the same army, in between any person can trap the data when it is
transmitted through wireless.
Our aim of the project is to protect the data from the ensnares.
To accomplish this, we have used a PC as a sender and PIC
microcontroller as a receiver station. The message to be sent is fed in to
the computer for different units. The computer will Encrypt the data using
generating a duplicate Character for a real one.
At the receiving end the PIC microcontroller then Decrypts the
Received data and displays the message on the display. The
