Hi everyone,
|
|
|
|
The BLAKE2b hash of `./response` is:
|
|
5ac5c062 dc7eadd4 8bb9e40e 8ff8a75d
|
|
2582f9d7 f4a78613 0855101a aa817dd3
|
|
bd2553be 4c17b43d 94631f64 20df660b

I performed the computation using https://github.com/ebfull/powersoftau/
|
|
at commit d47a1d3d1f007063cbcc35f1ab.
|
|
|
|
I used a low-cost, brand new, airgapped laptop and a set of fresh USB
|
|
sticks. The laptop had never been connected to the Internet and never
|
|
will: it was destroyed once its fulfilled its purpose.
|
|
|
|
The computation took place in an empty meeting room in the basement of
|
|
the Jen-Hsun Huang Engineering Center at Stanford University. I attended
|
|
the machine at all time during and after the computation. The building
|
|
has a high-concentration of different equipments, and multiple labs,
|
|
hopefully making it hard to single out emanations from *my* machine
|
|
(short of having a Faraday cage...).
|
|
|
|
After the computation finished, I copied over the challenge response and
|
|
the associated B2b hash, rebooted the laptop twice, and used a shredder
|
|
to give it the coup the grace later in the evening.
|
|
|
|
Best,
|
|
Erwan Ounn
