The monetary cost is most likely not the problem. Tacking on significant additional work is bound to consume more power and generate heat. Tiny devices often have thermal and power limits to consider.
- adgjlsfhk1 1y agoThe problem is it isn't significant work. You can perform ChaCha8 on pen and paper in ~30 minutes. It's literally 768 single cycle 32 bit integer operations.
- wakawaka28 1y ago768 single cycle instructions to do WHAT? To encode a few bytes or something? You can't convince me that the cost of cryptography is never prohibitive. Boldly asserting that your idea of "significant work" is universal for all applications isn't going to convince me, nor are weird anecdotes about tangentially related things.
