Hi,

Thanks for the link to Kenny's talk.

Stephen - The hard problem for automotive vehicles is that, even if
Quantum Computing never comes to pass, algorithms and various
implementations go on having new weaknesses found over time.
But decent performance requires hardware assist, in many cases.
But automotive ECUs are very unlikely to start have large FPGAs
added soon.  Replacing 100s of expensive ECUs in fielded vehicles
to allow practical algorithm agility is not going to happen.  This issue
that Michael Richardson mentioned is at the top of the list for the
automotive cybersecurity community.

Cheers,
- Ira
