Secure Data Transmission Through Zig-bee Module

Wireless technology has important role in today's world every vehicle operates hard functions in a wire connection. Using wireless connection in place of wired connection could prove to be productive in economic senses as it will have an effect on the weight, cost and performance. This process is useful in modern day to day applications of wireless communication. This paper proposes the design of secure data transmission, Enter the message this message is encrypted and then it is transmitted by Zig-bee module. The data which is entered at the transmitter section will be displayed on the GLCD for our convenience and so that data entry can be done in easier way. At the receivers end when the encrypted message is decrypted and is displayed on the GLCD. The mode of communication that used in this project is duplex data transmission over radio frequency. In this paper we propose a fast and secure encryption decryption technique using through which we can encode data and image
