This looks like creative use of statistics to sell this processor.
i.e. @"reported that at least five percent of the global electronics supply chain includes counterfeit elements that could "cause critical failure or can put an individual's data at risk,""
Lets separate point (A) "cause critical failure" from "can put an individual's data at risk". Also what exactly do they mean by "put an individual's data at risk". If the risk is data loss as in data corruption, then thats one thing, but this processor is designed to stop tampering at the microcode level to stop malicious hacking style access of the data. So lets split this into point (B) "data corruption" and point (C) "hacking the CPU".
So what percentage of "global electronics supply chain" counterfeits can compromise, (A), (B) or (C), i.e.
(A) "cause critical failure"
(B) Data corruption making data unusable
(C) Hacking the CPU
Ok, so counterfeit passive components like resistors, capacitors and inductors are very easy to counterfeit and so they are mass market counterfeit products. But counterfeit passive components can only compromise point (A) and (B) but are very unlikely to compromise point (C)
Also counterfeit discrete active components like various Transistors etc.. are harder to counterfeit so going to be statistically less of them (but they still happen), but more importantly they can compromise point (A) and (B) but are also very unlikely to compromise point (C)
So we are left with counterfeit complex active components like processors which are the only form of counterfeit products that can compromise point (A), (B) and (C) ... but if its a counterfeit processor, then this "shrink wrap" tamper evident CPU design isn't going to be of much use as they then have access to change the CPU design anyway.
Also by far the vast majority of counterfeit active components like processors turn out to be simply empty packages. They look real, until they are powered up then you find you have an empty plastic package with leads that go nowhere once inside the package. They are also high value items for counterfeit gangs so they earn a lot of money from them (so they do make a lot of them) but they are not a risk to point (C) because they do nothing. They are just little blocks of plastic with wires going nowhere.
So I'm having extreme trouble in reconciling this idea that counterfeit elements of any kind are relevant to this anti-hacking processor design product. It sounds completely like spin in the wrong direction. Sure microcode can be compromised but that has nothing to do with counterfeit components and everything to do with processor design flaws. So what they are really trying to say is everyone but them is designing their processor wrong, so please buy their design.
So all this talk of "five percent of the global electronics supply chain includes counterfeit elements" is a FUD story to try to sell their products. Sure microcode hacking is a potential issue. But what percentage of a market do they really have for this level of protection. Its a useful feature but why all the FUD to try to sell it. Plus like others have said, the vast majority of hacking is using valid instructions so hardware protections of the CPU are not going to work to stop the vast majority of security holes.
