A Chinese lab claims it has created an MCU "invulnerable" to external attacks

scmp.com

I haven't found more info, but this claim sounds exaggerated, I don’t understand why with 3 cores, instead of 1, it can’t be attacked?

> The developers said the new MCU – about the size of a US quarter – had three cores rather than one, allowing two to function normally if one was attacked, according to the report

The lab that developed this is backed by the Chinese government. It's likely the extra cores are running code for the MSS from the start.

it could help things like tracking taint which is actually very effective against exploits... it does depend on how they use the cores ofc and the statement like that is super unclear. also the '100 times less hackable' seems super arbitrary...

say some attempt to exploit corrupts some value somewhere, another core could validate its become corrupted or unexpected.

there was a guy who implemented this on qemu (minemu i think). taint tracking that is. that was super effective at stopping really reliable exploits 100% of the time.

ofcourse, thats just my guesswork, and i am clueless how this chip would actually work... :)
