Reminder: The ROCA paper authors say you can break bad RSA 2K keys for $20k, but someone might optimize that to $200 in short order.

I did the brute force for the 3DS boot ROM RSA padding fail. A 1080 Ti can do 60,000,000 2048-bit modular multiplies per second.
Just found your slides. Nice! Yeah, this kind of 20x "how about we think before we brute" speedup is exactly the kind of thing I had in mind
