Every day, we’re connecting more and more devices over the internet. No longer does a household have a single connected computer — there are smartphones, tablets, HVAC systems, deadbolts — you name it, it’s been connected. As the Internet of Things proliferates, it has become readily apparent that security is an issue in this space. [Andreas Spiess] has been working on this very problem, by bringing HTTPS to the ESP8266 and ESP32.
Being the most popular platform for IOT devices, it makes sense to start with the ESP devices when improving security. In his video, [Andreas] starts at the beginning, covering the basics of SSL, before branching out into how to use these embedded systems with secure cloud services, and the memory requirements to do so. [Andreas] has made the code available on GitHub so it can be readily included in your own projects.
Obviously implementing increased security isn’t free; there’s a cost in terms of processing power, memory, and code complexity. However, such steps are crucial if IOT devices are to become trusted in wider society. A malfunctioning tweeting coffee pot is one thing, but being locked out of your house is another one entirely.
We’ve seen other takes on ESP8266 security before, too. Expect more to come as this field continues to expand.
