Now a day’s extended number of wireless communication users have increasing demand of security and protecting data transmitted by the user over unsecured network so that unauthorized persons cannot access it. the data share through wireless network so it must provide data with authentication. The security between the wireless devices is most important part in wireless communications. Bluetooth is small range and the low power consumption that connect through various devices. This project presents the development of secure wireless connection terminals on a field programmable gate array (FPGA). The wireless connection has been established using Bluetooth technology & XBee and the initialization of a secure algorithm for data exchange is implemented using the advanced encryption standards (AES).The proposed system has been validated and demonstrated using an image processing application which involves the encryption and decryption of acquired images from camera. The evaluation of different building block has been carried out in terms of speed, distance and time.

Keywords: FPGA, AES, cryptography, VHDL, encryption/decryption implementation
