Wireless Data Encryption and Decryption Using RF Communication
The main aim of WIRELESS DATA ENCRYPTION AND DECRYPTION USING RF COMMUNICATION project is to transmit encrypted and receive that data through RF. TLP434A RF transmitter is used in this project. Frequency used for transmitter is 433.92MHZ. In remote control applications this ultra small wireless transmitter is used. This transmitter operates between 2V to 12V. This project uses micro controller as a decoder. Before data is transmitted by transmitter data is displayed on LCD screen. Transmitter signal is generated at 433MHZ frequency. On the receiver side antenna will receive the signal and send it to receiver. And the data is send to micro controller for further processing.
