Other Projects

  1. RF Fingerprinting Based Authentication for Bluetooth Low Energy
    Internship project in Massachusetts Institute of Technology
    This project attempts to authenticate Bluetooth Low Energy (BLE) transmitters by identifying them through features extracted from their transmitted signals (RF Fingerprinting). Such authentication in meant to prevent battery drainage attacks on ultra-low power bluetooth receivers for IoT networks. My contribution was in developing a feature extraction pipeline and neural network for RF Fingerprinting, and reducing the energy consumption of this system.

  2. Digitally Programmable Analog Computer
    Electronics Design project in IIT Bombay
    We designed an analog computer to simulate linear dynamical systems in real time. It was made digitally programmable by using an on-board microcontroller which can be programmed via a serial interface. This project was supported by Prof. Mukul Chandorkar, dept. of Electrical Engg. IIT Bombay for hardware-in-loop simulations in the power electronics lab.
