Wireless Data Encryption and Decryption For Security In Army Applications

Everyone in this world wants to be safe and secure. Even a small kid tries to protect his toys in a safe place. The situation becomes more complicated when it comes to Multinational companies, Military, Army. Even a common man puts his maximum efforts to protect his data.

One of the popular methods to protect the data in a more secure way is to encrypt the data while sending and when received, decrypt the data to retrieve the original message. Before transmitting the data, the data will be converted into an unreadable form and will be sent. At the receiving end, the reverse of encryption carries on to get back the original message. Thus the data will be protected in every way by following the encryption and decryption standard formats. Wireless makes this project more flexible. Standard algorithms require software to be installed into the system before actually using them and hardwired connections. The hardware connections and cabling can be completely eliminated in this project.

The most efficient and reliable wireless communication is RF. The RF modules used here are 2.4 GHz UART. The data entered from the PC keyboard is sent to the microcontroller at the transmitter side. The microcontroller converts the data into unreadable form i.e., encrypts the data and then passes the encrypted data to the RF transmitter.

At the receiver end, the RF receiver receives the data from air. The same data is sent to the microcontroller. This microcontroller receives the encrypted data, decrypts the data i.e., finally converts the data into a form suitable for the user to read. This decrypted data can be seen on the receiver PC. Thus, the data is protected while it is transmitted and received between two PCs.
