Make a hack-proof garage door opener: A new breakout board offers cryptographic security - [Hands On

Abstract

I'VE BEEN MAKING ELECtronics projects for 15 years, but strong security was something I always considered out of my reach. Consequently, a fear of getting hacked limited the types of projects I would pursue, especially Internet-connected devices. But in May of 2019, I was handed the job of designing a cryptographic product for my employer, SparkFun. Among other things, SparkFun designs and sells breakout boards that allow makers to easily incorporate the capabilities offered by various integrated circuits into their designs. Now SparkFun wanted a board that would provide an easy on-ramp into the world of hardware-based cryptography.
