# Powers of Tau Attestation
|
||||
|
||||
Author: devrandom
|
||||
Date: 12 March 2018
|
||||
|
||||
Notes:
|
||||
|
||||
* Hardware is an Intel laptop that has not been powered up in four years
|
||||
and has never been connected to a network after it was purchased. CPU was
|
||||
a Celeron 1007U. Wireless card was removed.
|
||||
* OS was a clean Ubuntu 14.04
|
||||
* Compute binary was created with a deterministic Gitian build, with report
|
||||
here:
|
||||
https://github.com/devrandom/golang-powersoftau/commit/241da6dac6166a68ff20ef7abbb0f8231a626a3c.
|
||||
The binary sha256sum is
|
||||
c28894877c8948960eaefa0d8f35da6c911031980672b983f361711a7dcb1ec8. The
|
||||
binary was archived for future research.
|
||||
* A USB drive was purchased in person and used to transfer the binary and
|
||||
challenge into the laptop and the response out of the laptop.
|
||||
* Additional entropy was injected into /dev/random via keyboard mashing and
|
||||
dice throws
|
||||
* The laptop was disconnected from AC throughout the computation
|
||||
* The boot drive was destroyed
|
||||
|
||||
The BLAKE2b hash is:

|

Date: March 12th, 2018
|
||||
Time: 6:00pm to 8:00pm PDT
|
||||
Location: San Francisco, CA
|
||||
|
||||
For the compute node of my Powers of Tau contribution, I used a
|
||||
refurbished late-2011 15" MacBook Pro, hardware which I've owned for
|
||||
2.5 years, running Tails 3.5 off a USB stick.
|
||||
|
||||
I downloaded and compiled Filo Sottile's Golang implementation
|
||||
(https://github.com/FiloSottile/powersoftau) using Go 1.10 in Ubuntu
|
||||
17.10 on a separate desktop computer. I wiped another random USB stick
|
||||
in my possession and copied the 'taucompute' executable and the
|
||||
challenge file. Every time I copied the executable (on/off USB sticks,
|
||||
onto computers, etc.) I checked the SHA256 hash, which stayed the same
|
||||
throughout the process:
|
||||
|
||||
79c56ad4f1422ec134adac02857dc168a98e663041ca65e88ee903712eaf489d
|
||||
|
||||
This executable is available for inspection here:
|
||||
|
||||
https://drive.google.com/file/d/1Dl_avSDNR1A1lcWH8oEmWp-VNsGvNQkp/view?usp=sharing
|
||||
|
||||
I always wanted to use the coolest Faraday Cage I could find, so I set
|
||||
up my compute node in the top shelf of my apartment's fridge. Prior to
|
||||
initiating computation, I disconnected and powered down my apartment's
|
||||
wireless access point and manually turned off every device within 10
|
||||
feet of the fridge that had a radio. (note that I used my phone in
|
||||
airplane mode to take pictures after Tails booted...but I turned it
|
||||
off before computation began)
|
||||
|
||||
I added randomness in an undisclosed manner before beginning
|
||||
computation. Computation began around 6:20pm PDT and finished at
|
||||
7:10pm PDT--no doubt my cool Fridge-aday Cage sped things up a bit.
|
||||
The fridge door was closed most of the time, but I periodically opened
|
||||
it (every 15 minutes) to check on computation. I never left the fridge
|
||||
out of my sight--and yes, there's definitely a "running fridge" joke
|
||||
here somewhere.
|
||||
|
||||
Afterwards, I copied the response file onto another USB stick (along
|
||||
with the 'taucompute' executable) and copied them both back onto my
|
||||
desktop. The BLAKE2b hash of my response is:
|
||||
|
||||
822885fe 28daad52 2ff771fc 849eaa1c

||||

|
||||

|
||||
|
||||
I tweeted the BLAKE2b hash of my response file here as well:
|
||||

||||
|
||||
My PGP public key is available via Keybase:

||||

||||

|
||||
|
||||
I plan on destroying the Macbook Pro in a manner that will be revealed
|
||||
in a future blog post. Until then it remains powered off in my fridge
|
||||
except when I transport it for destruction.
|
||||
|
||||
Thanks to Sean Bowe and everyone at the Zcash Company for building
|
||||
this incredible MPC, Jason Davies for organizing, and all the other
|
||||
participants in Powers of Tau! Glad I could contribute and make my
|
||||
first full-time day at the Zcash Foundation memorable. :)

My part of Powers of Tau was performed on a Penguin Adelie GNU / Linux
|
||||
Laptop by Think Penguin.
|
||||
Processor: Intel(R) Core(TM) i7-6700HQ CPU
|
||||
OS: Debian GNU/Linux 9.3 (stretch)
|
||||
|
||||
Downloaded the challenge file and compiled the Go implementation. Then I
|
||||
disconnected from the ethernet and unplugged the router. All devices,
|
||||
besides the computation node, with a possible network connection,
|
||||
microphone and/or camera were put on the other side of the apartment, as
|
||||
far from the computation node as possible. Batteries and sim cards were
|
||||
removed from all of those devices if possible.
|
||||
|
||||
Randomness was added via mashing buttons for a while and then entering
|
||||
the sha512 hash of an audio file recorded at a street market earlier
|
||||
today, followed by more button mashing.
|
||||
|
||||
The response file and BLAKE2b hash were then saved securely and I
|
||||
shutdown the computation node. After a short period of time and a snack,
|
||||
I booted the computer and uploaded the response file.
|
||||
|
||||
The BLAKE2b hash of `./response` is:
|
||||
1d4530ec 2bc7c6c4 fa5d6491 acbfe0b3
|
||||
e1ec1208 5bc0b4b0 a1ebef5c f0d71a1d

|
||||

|
||||
|
||||
The hash was also publicly tweeted:

||||

I'm happy to have been able to participate. Thanks everybody who made
|
||||
this possible!
