Objective: Generally there are numerous approaches to give security information that is being imparted. However, what if the security is assured irrespective of the hackers are from the noise. The Information Security is essential concern towards each communication system. Methods/Analysis: XBee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, XBee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. Finding: This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area. This paper describes a design of desired security for data communication by designing standard algorithm for encryption and decryption. The process occur in this module was based on encryption and decryption. The source information is generated by a bit file and this will be encrypted and is sent to destination through XBee modules. The receiving system will check the data and decrypt according to a specific algorithm and displays on the LED. Applications/Improvement: The present algorithm is implemented in Verilog HD Land simulated using Xilinx ISE simulator tool. The design is implemented on Xilinx Spartan-3 EFPGA development board. This project has applications in encoding and decoding operations for security purposes.
