Let’s connect our front door to the internet! What could possibly go wrong? Securing IoT is hard, and the last thing we want to do is let some stranger in. Let’s take a step back and consider other ways of securing that door, and granting access remotely, without connecting your door to the internet, while adhering to common protocols and data formats throughout. By mixing up a little near-field communication with JSON Web Tokens, sprinkling some rich communication services and a fairly simple native mobile app, we should be able to create and demonstrate an effective security process for letting the milkman in! Join me on this interactive journey and maybe when one door closes, another will, actually, open.
