Now-a-days, extended number of wireless communication users has 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 paper presents the development of secure wireless connection terminals on a Field Programmable Gate Array (FPGA).
