And everyone keeps sourcing their SEs from a company (Microchip) which had made 3 revisions of their chip with only ROM changes and still has not fixed the root cause of flaws in the ATECC508A, 608A and 608B (used in a lot of HWWs) which is that there is no light sensors or self-terminate mechanism in the case of an attack

Their way of rating chip security is via the JIL rating system which is a very low bar to pass and involves the vendor coming up with their own numbers on how hard it could be to attack it, which they conflate with EAL5/6 because that is a lot harder and expensive for what is supposed to be an IoT SE nostr:note1upvg0s73kj57387rpq3zq55jm29fsrf838vnps79k3zzk3ypaldshhpnft
