A lot of buzzwords for one title!<p>The upshot seems to be that when running the Mongoose operating system ( <a href="https://github.com/cesanta/mongoose-os" rel="nofollow">https://github.com/cesanta/mongoose-os</a> ) on an ESP8266 WiFi device, you can use a Microchip crypto accelerator ( <a href="http://www.microchip.com/wwwproducts/en/ATECC508A" rel="nofollow">http://www.microchip.com/wwwproducts/en/ATECC508A</a> ) to do <i>something</i> with TLS.<p>Mention is made of hardware-secure credentials but not actually explained (is this TLS client certificates?)
