Rapid prototyping of AES encryption for wireless communication system on FPGA

This paper proposes a wireless communication system for secure transmission of data. Bluetooth is used as the wireless communication medium due to its low-cost and low-power consumption features. Advanced encryption standard (AES) protocol is implemented for the security reason over Bluetooth stack. RC10 prototyping board with Xilinx XC3S1500L-4-FG320 device has been used for the hardware evaluation of the system design. The system is configured to capture frames in real-time from the on-board OminiVision 9650 CMOS camera and transmit these frames securely via Bluetooth´s connectivity. On reception, the images are decrypted and displayed on the external monitor. The design has also been demonstrated for edge detection over the wireless communication channel. The overall design is evaluated in terms of resource utilisation and maximum operating frequency.
