Imagine billions of smart devices – such as fitness trackers, home sensors, and traffic monitors – working together around the world. These Internet of Things (IoT) devices make life easier, but they face two major challenges: staying secure and saving power. My research looks at the tricky balance between the two.
Right now, many low-cost IoT devices skip proper security because encryption can drain batteries faster. But leaving them unprotected opens the door to hackers. I'm working on lightweight security solutions that keep devices secure without burning energy. I'm testing different wireless technologies to study how security features affect battery life. My goal is to create a framework to help developers choose the best technology, whether for a smart city sensor or a wildlife tracker.
In the end, my research helps make IoT devices safer, longer-lasting, and greener. If each device saves just a few milliwatts, that may not sound like much. But with more than 18 billion devices worldwide, those tiny savings add up – like shutting down dozens of power plants or keeping millions of homes running on clean energy. It's proof that small changes can lead to a greener, more secure future.
Students will be involved by analyzing case studies of previous IoT attacks and discussing how they could have been prevented. If time allows, I will also show a live demo of a simple IoT device and how it can be hacked.
