:The increased incidents of data tampering and stealing have become a matter of concern around the globe. To prevent from such malicious activities, cryptography modules is widely used in many sectors. In this paper, a wireless cryptography algorithm prototype is developed. The design is demonstrated using Present Light weight cryptography algorithm on Basys 3 Artix 7 FPGA board. The Arm cortex M3 STM32F10C8T6 microcontroller is used to interface with Bluetooth (HC-05) module
