Wireless Data Encryption & Decryption for
secured Communication using RF
Software used: Embedded C, Keil, Proload
Domain: Embedded Systems Design
Microcontroller used:AT89S52
Power Supply:+5V, 500mA Regulated Power Supply
Transmitter Display:LED 5mm, 16 X 2 LCD
Receiver Display:LED 5mm, 16 X 2 LCD
Communication Device: RF Module
Applications : Mobile communication, Wireless Communication
A design of effective security for data communication through a standard algorithm for encryption and decryption design is described here. The source information is generated by a key pad which is then encrypted and then sent to destination through RF communication. The receiving
system decrypts the data according to a specific algorithm and
displays on the LCD.
STT-433 MHz Transmitter, STR-433 MHz
Receiver along with HT640 RF Encoder and HT648 RF Decoder is used in this project. RF Transmitter is
connected to the different sensors through RF Encoder. 8-bit data is converted into a single bit and transmitted serially. the receiver receives this analog value on a single data line and passes this data
to the decoder which does the serial to parallel conversion. 7805 three terminal
voltage regulator supplies 5V. The block diagrams are given in this pdf:
