Is it me or is one of the main RISC-V advantage is that it's free of mandatory backdoors ? Why would you need this enclave ?
- jeroenhd 4y agoTrusted execution environments can serve all kinds of useful purposes. Secrets management (TPM/tokens/etc.) is a very common use case, as is DRM (though I don't expect too working DRM on a RISCV system). If the chip can be disabled or if its firmware can be controlled with custom signatures (i.e. a ROM managed through an open boot mechanism such as coreboot) then I don't see any problems with such a core, even in a fully FOSS system. It's unlikely that this freedom will actually be given to customers, but I don't see any theoretical problems here.
