I think you are confused. RISC-V is just an ISA, not a hardware design, so it can't have a backdoor or, on the other hand, be free of them.
- hajile 6y agoIt's a related idea. With a closed ISA, the only manufacturers are closed-source and I can't verify the chip is secure under any circumstances. With an open ISA, I may not be able to verify all designs are secure, but, I can verify that some are secure and choose one of those.
- nsajko 6y agoNo, there is no relation. You are conflating the ISA with its hardware designs. I'm not an expert, but imagine an ISA being like a C library API, in that case the hardware would be the APIs implementation.
