(3/3)

However there are no real implementations using ARM CC310 known on nRF52840 yet, Nordic are (logically) careful with any promises and if you google Trustzone vulnerabilities it seems that many real implementations are vulnerable to fairly common attacks. So it gives a hint that many people are just using it as sticker and values security by numbers of prays per day then understanding the backgrounds.

(btw. very similar could be said about the fancy mesh networking, Internet of Things and other stickers... most of real products don't need anything from that and very often it even makes the product worse;)
