Simplest solution here is to implement the algorithm in hardware, with a new instruction that has all the security attributes. (Including resistance to power differential and timing differential attacks.)

- sounds 4y agoTrue. But did you want a microcode vulnerability? That'd make for another one of these awesome HN discussions...
- mordae 4y agoThen start adding FPGAs! Seriously, this has been talked about for ages now. If every platform had a good enough FPGA, it could be used for cryptography and/or to accelerate some specific computations. Abd without having a set of algorithms baked into the silicon, it would not make the device eventually obsolete as the world moves to better algorithms.
- littlecranky67 4y agoNot only has it been talked about for ages, Intel bought Altera and AMD bought Xilinx. One has to wonder and ask - why? Edit: > it would not make the device eventually obsolete as the world moves to better algorithms Ah there I found it. Makes sense to buy the FPGA manufacturers, so they devices still become obsolete and people buy their newer processors.
