> these tiny parts usually run with high privileges and dramatically impact the overall system. In such cases, MTE/CHERI play pretty nicely - they help ensure that whatever bugs we have in these areas are killed at their root cause (probabilistically/deterministically). This is exactly why MSR, MSRC and Azure Silicon pushed for this AMAZING project of CheriIoT ... scaling CHERI down to RISC-V32E, the smallest core RISC-V specification. I’m very excited about this project, and I hope once we will open-source the ISA and the prototype, more folks across the industry could join.
That is a direction that would benefit everyone: open silicon and open firmware for the most security sensitive components. It is technically possible and at least some humans in big companies understand why it is necessary for our future would-be-digital civilizations.
