IoT Security Applied on a Smart Door Lock Application

Sammanfattning: This thesis describes the development of an IOT application based upon Digitizing a smart door lock for making it connected to the internet and able to recognize employees that work in the office. This thesis concentrates primarily on the security aspects by listing the typical security challenges in IOT systems in general and summing these challenges up to develop a functional and secure product from scratch. A microcontroller is chosen for this project and a test environment is built to experiment and develop the security breaches. Architectural designs are chosen for the API being developed and even for the Android Application. A detailed description is made of the multi-master database represented by Azure active directory and its importance to achieving the security of an essential security breach. A new technique called Eddystone is introduced in the project to serve the transmission protocol with Bluetooth beacons. The final stage of this project is completing the development of the Android application and making sure that all the subsystems developed do communicate with each other, to deliver a functional and secure flow of the IoT system.
