Efficient FPGA Implementation of a Secure Wireless Communication System Using Bluetooth Connectivity

In early days, the data transfer was done by wired media like co-axial cable(s), fiber optic cable(s) etc. The era has gone. Nowadays wired media is replaced by wireless means, for which Bluetooth is the best suited choice. This project emphasizes that wireless communication system for secured data transfer can be implemented by the Bluetooth connectivity. Bluetooth devices are short range and meant for low power utilization, allowing communication between various devices. The Advanced Encryption Standards (AES) algorithm is used in order to provide the security to the data. This project analyzes the development of fully secured wireless connection terminals on a FPGA where connection is established using Bluetooth technology and an advanced encryption standard (AES-128) for encryption and decryption is used to initialize the secured algorithm for data exchange. The prototyping board equipped with Xilinx Spartan-III-XC3S250E-4PQ208 FPGA device is used for hardware evaluation of system design. For simulation part, Xilinx ISE Design Suite 14.2 is used as the simulation tool and architecture was implemented by Verilog. The proposed system has been validated and demonstrated using the application which involves the encryption and decryption of data and evaluated in terms of resources used and throughput obtained.
