It wasn't clear to me, unless I'm missing something, if arbitrand uses hardware external to the FPGA or not, if it does, what type of RNG does it use?
If it's purely FPGA based, is it ring oscillator based?
- pclmulqdq 3y agoYes, FPGA-based, and no ring oscillators. AWS doesn't allow you to use latches or comb loops at all, but has the same area efficiency as the best RO-based designs. We'll publish eventually. For the FPGA users out there - we will be packaging a few shapes of RNGs as IP in the near future, but this kind of chip/FPGA IP needs a LOT of very subtle verification, which made a lot more sense to do for full cards first.
